Rory McIlroy said he and co-leader Viktor Hovland "fed off each other" in a thrilling third-round pairing at the Open Championship.
The duo each carded 66s on moving day at St Andrews to share the 54-hole lead on 16 under par, four shots ahead of nearest rivals Cameron Smith and Cameron Young.
McIlroy's stunning hole-out eagle from the bunker on 10 was the highlight of his round, though he gave a shot back on 17th after clattering into the wall down the right side of the notoriously tricky Road Hole.
A pair of birdies at the last ensured McIlroy and Hovland will head out on Sunday level pegging in pursuit of the Claret Jug at the landmark 150th edition of golf's oldest major.
"I thought it was really good," the Northern Irishman, who was crowned Champion Golfer of the Year in 2014, said of his round.
"I missed some opportunities early and Viktor holed a couple of long ones early on.
"But I stayed really patient, got my first birdie of the day on five, and I feel like my patience was rewarded around the turn with a couple of birdies and that hole-out on 10.
"Overall, a really good day. We sort of fed off each other, and navigated the last few holes well. It was tricky coming in there.
"When you're a couple off the lead going into the third day of The Open and you go out and shoot a six under, you're always going to be pleased with that."
McIlroy had magnificent backing from huge crowds on a glorious day on the Fife coast and he was grateful for it, but keen not to get carried away.
"The support that I've gotten this week has been absolutely incredible," said the four-time major winner.
"I appreciate it and I feel it out there, but at the same time I'm trying my hardest just to stay in my own little world because that's the best way for me to get the best out of myself.
"I try to acknowledge as much as I can, but I'm just trying to stay in my process, stay in my own little bubble and I just have to do that for one more day.
"I just have to just stick to my game plan, stick to the process. The more people bring up the result, the more I'm just going to harp on about process and sticking to my game plan, because that's the only thing I can do, and I've done that well for the last three days.
"It's put me in this position. I just need to do it for one more day."
Viktor Hovland says it feels "pretty crazy" to be heading into the final round of The Open in a share of the lead with a golden opportunity to make history at St Andrews.
Hovland and Rory McIlroy will be in the last group on what promises to be a pulsating finale in Fife on Sunday after the Ryder Cup team-mates shot sublime third rounds of 66.
The 24-year-old could become the first Norwegian to win a major if he holds his nerve to lift the Claret Jug.
Hovland was living the dream as he and McIlroy put on a show in the penultimate pairing to go 16 under on Saturday, taking a four-shot advantage over Cameron Smith and Cameron Young.
The Oslo native said: "It's pretty crazy from where I grew up and so far away from playing the PGA Tour, European Tour, for that matter major championships.
"Just to be here is very special, but to have a chance to win one is - yeah, I have to pinch myself, but that doesn't mean I'm going to hold back tomorrow."
There is nowhere Hovland would rather win at first major than the home of golf.
He said: "I don't think there's any other place that would top it. Growing up in Norway and always watched The Open Championship for way longer than I ever did, for example, the Masters. To win a major that's closest to home, that would be really cool."
McIlroy is the crowd favourite at St Andrews, but Hovland fancies his chances if he rises to the occasion.
He added: "I don't mind [the support McIlroy gets]. It doesn't take the pressure off of anything, but I feel like I had some experience with that in the Ryder Cup last year.
"And at the end of the day, there's still some shouts there for me as well. So I appreciate those. I've just got to play my game and not worry about anything else."
Rory McIlroy and Viktor Hovland will form Sunday's final pairing as the 150th Open Championship heads for a thrilling conclusion.
The duo played together on Saturday and both shot third-round 66s to claim a share of the lead on 16 under at St Andrews.
However, it is not quite a two-horse race at the famous Fife links, with Cameron Young and overnight leader Cameron Smith four strokes behind, while Scottie Scheffler and Kim Si-woo are within five.
The highlight of McIlroy's round was a hole-out eagle from the bunker on 10, but he and Hovland were both wayward on their approach shots to 17 as signs of nerves started to show on the notoriously tricky Road Hole.
McIlroy was close up against the stone wall to the right of the green and ended up with a bogey five, while Hovland – whose shot came to rest on the gravel path – recovered to salvage par and restore parity at the summit of the leaderboard.
A pair of birdies at the last kept it that way, setting things up for what promises to be a memorable final day at the home of golf.
Elsewhere in the field on an exciting moving day, Shane Lowry carded back-to-back eagles on the ninth and 10th before the 2019 winner faded on the back nine to sign for a 69.
Patrick Cantlay threatened to join the fun at the sharp end of things when he got to 11 under through 12, but he dropped three shots in the remaining six holes to end up eight off the pace.
SHOT OF THE DAY
McIlroy turned a threat into an opportunity after putting his tee shot into the bunker at the 10th, with rival Hovland having landed safely short of the pin.
A superb bunker shot pitched just shy of the cup and rolled in for an eagle two that piled the pressure on Hovland.
To his credit, the Norwegian got down in two for a birdie that ensured he stayed level with his playing partner.
PLAYER OF THE DAY
On moving day in Fife, it was crowd favourite McIlroy who really clicked into gear.
A pre-tournament favourite, the 33-year-old found his groove to chart a course for his fifth major and first since 2014.
On this form, he will take some stopping on Sunday, even with Hovland for company.
CHIPPING IN
Jordan Spieth: "What's difficult about it is a lot of the pin locations are in these tiny little tucked corners where, if you hit it more than five feet by, it goes 50 feet away."
Shane Lowry: "It wouldn't take Einstein to figure out what went wrong on the back nine. My putting was horrific."
Bryson DeChambeau: "I don't think you ever know how to play this golf course fully. Every day it's different. It showcases a unique golf course each time the wind pops up or doesn't pop up. It's just different."
A LITTLE BIRDIE TOLD ME
- When McIlroy won The Open in 2014, he was 16 under after round three.
- The pairing of McIlroy and Hovland produced just one bogey between them on Saturday.
- Every winner of The Open at St Andrews has been within four shots of the lead heading into the final round.
Australia head coach Dave Rennie refused to use the Wallabies' lengthy injury list as an excuse for their series defeat to England.
Eddie Jones' side added to their tour triumph in 2016 by making it back-to-back series wins Down Under, beating Australia 21-17 in the deciding Test on Saturday.
The tourists fell behind in the series after going down 30-28 in Perth, but levelled up with a 25-17 win in Brisbane last weekend.
Australia started brightly on Saturday, moving 10-3 ahead after Tom Wright's try. England recovered as Freddie Steward and Marcus Smith went over to turn the contest firmly in their favour at 21-10, and stood firm after Folau Fainga'a powered over later on.
The hosts were without 11 players due to injury or suspension, but Rennie believes his side should still have had enough quality to overcome England.
"We had a good enough side on the field to win tonight," he told reporters. "What it highlights is we're creating really good depth and I think a lot of guys who've got an opportunity have really stood up.
"You've just got to find a way, don't you? Injury is part of the game and we did enough tonight, but you have to be clinical and take opportunities.
"We created a lot of opportunities. I think we went in with the right plan, we just weren't clinical enough.
"If we turn a couple of those opportunities early on in the game, we start applying pressure to them. It's disappointing because at this level you have you got to take your chances and we left a lot out there."
Australia captain Michael Hooper conceded the series loss hurts, and also called on his team-mates to become more clinical.
"Dave's talked about just being clinical in those situations, you want to be a team that can grind out a win," he said.
"They get to your end, they take points, pick up some scraps there, get more points, and then you have to start looking at the line, try to maul, we can't just do 3-6-9 walk on them.
"Their ability to stack points on was a credit to them across the series, and they just keep applying that pressure with their kick game.
"England did really well there. They had injuries too so they grinded out a series win.
"In terms of our learnings there's a heap for us. We've blooded some new players so that's a great thing. With injury comes opportunity.
"We were hurting last week, now we're going to be hurting even more. So it's going to be a long three weeks until we play again."
New Zealand head coach Ian Foster avoided questions over his future after the series defeat to Ireland, saying "I just want to talk about the test match."
The Irish had previously not won in 13 away games against New Zealand, but a 23-12 triumph last weekend gave them the opportunity to make even more history.
And a magnificent Ireland performance in a 32-22 victory in the decider condemned the All Blacks to their first home series defeat in 27 years.
The result also meant that New Zealand lost two games on home soil for the first time since a pair of defeats to South Africa in 1998.
In the post-match press conference Foster was quizzed about his future, to which he replied: "I just want to talk about the test match."
The 57-year-old was quick though to heap praise on Ireland, telling reporters: "New Zealanders have probably got to realise that this was a very good Irish team.
"Give them some credit. I think it would be disrespectful for us to not make that the number one item.
"They've come and achieved something pretty special here, and I think they deserve a bit of time in the sun for that."
Foster was also puzzled at New Zealand's lacklustre performance, with the 22-3 score they faced at half-time the largest 40-minute deficit in All Blacks history.
"For some reason we're just not as calm," Foster added.
"In the defence area we're getting a bit fidgety, there's a few holes.
"Ireland aren't a team you can let get behind because that is when they play an up-tempo game.”
Juan Soto has rejected a 15-year, $440million extension from the Washington Nationals, who now plan on listening to trade offers for the star outfielder, according to reports.
The deal would have made the 23-year-old the highest-paid player in Major League Baseball history, surpassing Mike Trout's 12-year, $426.5m contract with the Los Angeles Angels.
According to Ken Rosenthal of The Athletic, the Nationals will now look to entertain trade offers for Soto ahead of the August 2 deadline.
Soto is making $17m this year and will not be an unrestricted free agent until after the 2024 season, so the Nationals have him under control until then.
General manager Mike Rizzo told a Washington D.C. radio station last month that the team had no plans to trade Soto, but the mood appears to have now changed.
"We are not trading Juan Soto," Rizzo said in early June. "We made it clear to his agent [Scott Boras] and to the player… We have every intention of building this team around Juan Soto."
Boras spoke about Soto's future at MLB's general managers meetings in November.
"Juan Soto wants to win," Boras said. "So the first thing that's going to have to happen is that he knows that he's working with an ownership that's going to annually try to compete and win.
"And then I think once he knows that, then he'll be ready to sit down and talk whenever they choose to talk."
The Nationals are struggling again this season, entering Saturday with the worst record in the majors at 30-62.
That comes on the heels of Washington's last-place finish in the National League East last season (65-97) and a 26-34 record in the 2020 pandemic-shortened season after the franchise won its first World Series title in 2019.
Soto is also having a bit of a down season despite recently being named an All-Star for the second time in his career, hitting .247 with 19 homers and 42 RBIs in 89 games after entering the season with a career batting average of .301.
Ian Poulter took aim at the media after his third round 70 at The Open on Saturday, saying he has been getting plenty of support from the crowd at St Andrews.
The Englishman received a frosty reception from some at the famous course when he teed off on Thursday following his defection to LIV Golf, though he said he only heard cheers.
Poulter seemed to receive more favourable crowd reactions on Saturday as he moved to five under heading into the final round in Fife.
When asked about getting a better from the huge crowds after his round, a spiky Poulter replied during a news conference: "Are we still talking about it? Did you hear one bad comment?
"It's amazing how we still talk about one person that's 100 yards down the first [hole], where there's conveniently a microphone positioned halfway down the stand and some young guy says 'boo', and it comes over on the TV. And you all assume I'm being booed on the course.
"Paul Casey [another LIV Golf competitor] walked 17 holes on day one... And the 17 holes he walked, there was not one comment. There was not one boo. If you guys continue to write that there are people and there's negative comments and there's boos, then unfortunately that's not a true reflection of exactly what happened.
"It would be really nice if people would actually write the truth, that we're getting quite a lot of support out there on the golf course because it would just be nice. It would be a fair reflection of actually what's happening, rather than this continual press of 'let's lead down the path of players being booed who have joined the LIV tour.'"
Poulter says nothing will stop him from enjoying what he says will be his last Open at such an iconic venue.
"This is my fifth Open at St Andrews. It will be my last Open at St Andrews," he told reporters. "I've got my whole family here watching. So I'm here to enjoy myself.
"The reception I've had has been remarkable, to be honest. I've enjoyed every part of it. It's been great not to read any rubbish in the press this week, which has been unusual for me to not read it.
"I've deliberately not read it, but just listening to some of the questioning is quite funny."
Handre Pollard claimed a 20-point haul as South Africa beat Wales 30-14 to win the Test series in Cape Town on Saturday.
Wales secured a historic first victory in South Africa last weekend to set up a decider at DHL Stadium, but the world champions outscored Wayne Pivac's side three tries to one to take the series 2-1.
Pollard put the Springboks in front with an early penalty and the fly-half then powered over from close range for a try following a sustained period of pressure.
Wales hit back courtesy of Tommy Reffell's first international try and Dan Biggar's penalty reduced the deficit to two points after South Africa lost Cheslin Kolbe to injury.
But the world champions were outmuscling the tourists at the set-piece and Bongi Mbonambi marked his 50th Test by charging over from the back of a ruck following a lineout late in the first half.
Another two Biggar penalties made it 17-14, but captain Siya Kolisi crossed after South Africa went through the phases just before the hour mark and Pollard added the extras.
Eben Etzebeth was then given a great ovation after he was replaced in his 100th Test, with the excellent Pollard making no mistakes with another two penalties late on as the Springboks deservedly wrapped up the series.
Michael Matthews held off a challenge from Alberto Bettiol to win stage 14 of the Tour de France, while Jonas Vingegaard kept Tadej Pogacar's challenge for the yellow jersey at arm's length.
The 192.5km race from Saint-Etienne to Mende saw a leading group of Matthews, Luis Leon Sanchez and Felix Grossschartner pull away with a few kilometres remaining, only for the chasing group to reach them inside the final 3km.
Bettiol then produced an impressive effort to not only catch Matthews, but overtake him, though the Australian came back to ultimately take the victory, his first in the Tour de France in five years.
The Team BikeExchange–Jayco rider had already finished second twice in this year's tour at Longwy and Lausanne, but showed immense grit to climb to the win on Saturday, producing a second wind to fight off the challenge of Bettiol and go one better.
Matthews achieved an average speed of 45.6km/h in the last 52km, and said after his win: "“I think it's pretty much the story of my career. I've had so many rollercoasters up and down but my wife and my daughter kept believing in me. How many times have I been smashed down but I always get back up?
"This was for my daughter today; she's four years old and I really just wanted to show her why I'm away all the time and what I do it for. And today was that day.
"Today was that day. I wanted to show everybody I'm not just a sprinter. I can ride like I rode today."
The battle for the yellow jersey saw Pogacar try to pull away from Vingegaard to make up some of the 2:22 second deficit on the General Classification leader, but the duo eventually finished with the same time, over 12 minutes behind Matthews.
The efforts of both against one another did see them pull away from Geraint Thomas, who remains in third place in the GC, though lost 17 seconds on the two ahead of him.
Mixed day for Aussie riders
It has been a bad time of late for Lotto Soudal rider Caleb Ewan, with a nightmare Giro d'Italia earlier in the year and a Tour de France to so far forget, including a crash during Friday's stage 13 leaving him injured.
The Australian did not have quite the Saturday his compatriot Matthews enjoyed, but Ewan's mission was simply to make it through within the cut-off time, which he was able to do, albeit nearly 40 minutes after Matthews had sealed victory.

Tommy Fleetwood is hoping his strong finish to Saturday's round has put him in the mix to challenge for The Open Championship.
Fleetwood made gains at the 14th, 15th and 18th holes to sign for a 66 and get to nine under at St Andrews.
It put him among the chasing pack on a day when conditions on the Fife coast were conducive to low scoring.
And Fleetwood, whose best finish at golf's oldest major was the runner-up spot in 2019, is optimistic he will be among the contenders on Sunday.
"It felt important," he said of his birdie at the last. "I birdied 15, parred 17 and birdied 18, but they all felt really important just being in the position we're in.
"We just can't afford to be dropping back too much and giving away too many chances at this point when you know the leaders are a long way ahead of you and you're trying to catch up.
"I'd have taken it [a 66] at the start of the day, that's for sure. I've just got to sit back and wait and see where we end up.
"It will be nice teeing off [on Sunday] feeling like we have a chance and see if we can get some momentum going on the front nine.
"It would be very cool and very special to be able to have a go again like down the stretch on a Sunday at The Open.
"I'll just wait and see. It's not in my hands. We'll ee what those guys do and if they get too far ahead, I'll be doing my best anyway, but it will be nice to have a chance, that's for sure."
Viktor Hovland sat at the summit through seven holes, the Norwegian getting to 14 under after starting the day on 10 under.
Playing partner Rory McIlroy was two shots back, level with overnight leader Cameron Smith and Cameron Young.
The American trio of Dustin Johnson, Scottie Scheffler and Patrick Cantlay were 10 under.
Eddie Jones believes England demonstrated they are heading in the right direction following the gutsy series victory over Australia.
Jones' side added to their tour triumph in 2016 by making it back-to-back series wins Down Under, beating the Wallabies 21-17 in the deciding Test on Saturday.
The tourists fell behind in the series after going down 30-28 in Perth, but levelled up by prevailing 25-17 in Brisbane last weekend.
They made a slow start to the third Test, falling 10-3 behind after Tom Wright crossed for the hosts. Yet England recovered as Freddie Steward and Marcus Smith went over to turn the contest firmly in their favour at 21-10, and they stood firm after Folau Fainga'a powered over later on.
It meant England lifted the Ella-Mobbs Trophy, justifying the backing from Jones. Despite a disappointing Six Nations campaign, Jones maintained a constant view that his team were making significant advances, which he feels has been justified by this series victory.
The head coach hopes the progress will continue as the 2023 World Cup in France edges closer, with his side aiming to go one better after losing 32-12 to South Africa in the 2019 final.
"We weren't at our best in this Test, but we kept fighting, and we kept in the game – particularly the defence of our finishers at the end was outstanding – and that got us the result," Jones told Sky Sports.
"We were just a little bit off, but we kept fighting, and it was a great effort by the leaders. It's a really positive step. We've always felt the team is going in the right direction. Sometimes, the results don't reflect that.
"At the end of the game, we had six players with under 10 caps, so it is an inexperienced squad who will really benefit from an experience like this.
"They understand how hard they have to fight to win a Test match away from home. Some of our guys have now won two series away in Australia. I am so proud of their efforts.
"We are in a good position. We have just got to slowly, slowly keep improving. We want to be at our best by next October."
Reigning champion Yulia Putintseva's Budapest Grand Prix title defence came to a disappointing end after she was beaten in the semi-final in straight sets by Aleksandra Krunic.
The Kazakh Putintseva struggled to get going, failing to convert any of her seven break points, as the Serbian Krunic broke her serve four times en route to a 6-2 6-2 win.
Bernarda Pera will await Krunic in the final in Hungary, after her 6-3 6-4 victory over Anna Bondar.
Bondar raced out to an early 3-0 lead in the first set, but Pera rattled off six games in a row to take the opener.
The Croatian-born American then won the first three games of the second set, before overcoming a desperate late Bondar charge to break her at 5-4 and finish things off.
Sunday's final will be the third meeting between Krunic and Pera with the latter winning both of the previous contests, firstly in the quarter-finals of the Guangzhou Open in 2018 and then in Moscow in 2021.
At the Ladies Open Lausanne, qualifier Olga Danilovic cruised through to the final with a 6-3 6-2 victory over Russian Anastasia Potapova.
Danilovic won her first WTA Tour singles event in Moscow in 2018, overcoming Potapova after three sets.
And the world number 124 was victorious against Potapova once more in Switzerland to seal her place in her second WTA Tour singles final.
The Serbian 21-year-old will meet Petra Martic in the decider on Sunday after Martic overcame sixth seed Caroline Garcia 6-4 1-6 6-3.
Neither player had dropped a set on their way to the semi-finals, but things at Lausanne were tied up at one set each after two.
Garcia had won all three of her previous meetings with Martic, but the Croatian's two crucial breaks of serve in the final set were telling, as she held her nerve to reach the final against Danilovic.
Wales were forced to make a late change for the decisive third Test against South Africa when Gareth Anscombe was ruled out due to a rib injury.
Anscombe came off the bench to kick the conversion that sealed a dramatic first win for Wales against the Springboks on South African soil last weekend, levelling the series at 1-1.
He will not feature at the DHL Stadium on Saturday after suffering an injury blow, so Rhys Patchell takes his place on the bench.
Captain Dan Biggar was passed fit to start at number 10 after recovering from a shoulder problem.
Wales are eyeing a first series win in South Africa after Wayne Pivac's side snatched their historic success over the world champions in Bloemfontein.
Andy Murray will continue to play professional tennis for as long as he keeps "seeing progress" in his game, the Scot has revealed.
The former world number one was knocked out of the Hall of Fame Open by Alexander Bublik on Friday, with the Kazakh winning their quarter-final 7-5 6-4 in Newport.
It follows Murray's disappointing second-round exit at Wimbledon to John Isner, and while the 35-year-old wants to see results improve, he was optimistic ahead of the switch from grass to the hard-court season.
"Obviously I just want the results to be a bit better," Murray told the ATP Tour website. "I felt like I had a good chance of [winning] here. If I got through Bublik, it would have been a good opportunity potentially in the semi-finals.
"But… to have my body feeling pretty good and getting lots of matches in is important for me."
Murray did have some success on grass this year, including reaching the final of the Stuttgart Open before losing to Matteo Berrettini.
"There were some good moments, but also some tough ones," he added. "Today's match and the loss at Wimbledon were disappointing and frustrating for me, but then I also had my best wins in a while in Stuttgart.
"So a bit up and down, but a little bit of progress overall and I'll try and keep that going through the hard-court summer.
"[I want] to continue to improve. If I keep seeing progress I’ll continue to keep playing."
Murray met NFL quarterback Kirk Cousins earlier in the week, with the Minnesota Vikings star praising the tennis supremo's "grit", and Murray revealed Cousins was looking to incorporate tennis into his own preparations for the new season.
"I'd never actually met any NFL athletes before, but he seemed like he loved his tennis and he was saying that he feels like a lot of the movements you make in tennis are similar to a quarterback," Murray added.
"He would prefer to do an hour of tennis to an hour of agility drills, which I can understand as you get a little bit older, trying to keep things fresh and fun in training in pre-season is important."
England captain Courtney Lawes hailed the determination of his team-mates after the tourists sealed a series victory over Australia on Saturday.
Eddie Jones' side made it back-to-back series wins Down Under - adding to their 2016 triumph - as they recovered from a slow start to defeat the Wallabies 21-17 in the deciding Test.
The hosts, who won the opening Test 30-28 before they were pegged back 25-17 in the second last weekend, dominated early proceedings at Sydney Cricket Ground, establishing a 10-3 lead thanks to Tom Wright's try.
But England came back before the break through Freddie Steward, while Marcus Smith also crossed in the second half to put the 2003 world champions in control at 21-10 to the good.
Folau Fainga'a went over late on as the hosts set up a grandstand finish, but Lawes and his team-mates stood firm to lift the Ella-Mobbs Cup.
"It really shows what it means for us to play this team," the skipper told Sky Sports. "We had a tough start to this series, but have showed what we're made of.
"We didn't come out how we wanted to today. The message at half-time was to stick together. We knew what we wanted to do. We showed what it means to play for this team.
"We did what we wanted to do to improve week on week. It's a proud moment, for sure.
"We've still got a lot to learn. We can win a game like this where you don't really fire a shot, and you take your chances when you can. We did a lot of defending."
Meanwhile, try scorer Steward also heaped praise on the efforts of Jones' side, saying: "The boys just dug in and gave everything. To win with an effort like that, it was a proper Test match. It's special.
"To come here, dig in with an effort like that at the back end of the season is pretty awesome. It is a great way to end the season especially having been one down is amazing."
Kevin Kisner took advantage of warm and still conditions at St Andrews to surge up the Open Championship leaderboard, as low-scoring at St Andrews looked set to be order of the day.
American Kisner needed two birdies in his final three holes on Friday to reach level par, the cut mark, and he capitalised on an early tee time on day three to card nine birdies in a seven-under 65, moving at least briefly into the higher reaches of the leaderboard.
American Trey Mullinax and Italian Francesco Molinari also went low with six-under 66s, after both began on level par, while South African Dean Burmester had a 67 to reach five under through 54 holes.
Bryson DeChambeau was also surging into contention, reaching six under for his round through 13 holes, helped by an eagle at the ninth.
That put him alongside Kisner on seven under for the tournament, with Tommy Fleetwood joining them after picking up four shots through his first six holes.
Kisner, 38, proudly held the clubhouse lead and told Golf Channel the conditions had been ripe for going low.
"It was very benign earlier, hole locations a little more accessible and not playing as much wind as we've had the last two days, with it being pretty warm too," Kisner said.
"So the ball was going pretty far, and it felt like you were aiming right at the flag for the first time all week."
The afternoon forecast was for slightly stronger winds, with the possibility of showers, but the Old Course was giving the players great scoring opportunities and that looked set to continue, even if Kisner hoped a storm would brew up.
"I hope the winds blows like hell, and they can all shoot over par and I have a chance tomorrow, but I think there's a lot of birdies out there," Kisner said.
"The guys are really good golfers. Hopefully, they don't get too far away, and I can still have a chance."
Australian Cameron Smith held the lead through 36 holes on 13 under par, putting him two ahead of American Cameron Young, with Northern Ireland's Rory McIlroy and Norway's Viktor Hovland one back on 10 under.
England made sure of only their second series victory in Australia after coming from behind to beat the Wallabies 21-17 in the third Test at the Sydney Cricket Ground.
Eddie Jones' side recovered in impressive fashion from a slow start that saw them trail 10-3 after Tom Wright's try.
The tourists hit back with Freddie Steward and Marcus Smith crossing, and they came under late pressure before securing another triumph Down Under, six years after their first.
England weathered a storm during the early stages; Noah Lolesio missing a first kick of the series before the right boot of Farrell put Jones' team in front.
The hosts soon established the lead that their early pressure deserved. Marika Koroibete's lay-off released Wright, who broke from just inside his own half and exchanged passes with Nic White before going over.
Lolesio booted the conversion and added a penalty, but England finished the half strongly. After Farrell trimmed the gap with a penalty, England edged their noses back in front at 11-10 when Steward crossed in the corner after a lengthy spell of pressure.
Farrell could not add the extras but stretched the England advantage with a penalty early in the second half, before Smith pounced on a poor lineout with a 55-metre sprint for the line.
Folau Fainga'a powered over 14 minutes from time to set up a nervy finish, but the tourists stood firm to seal the series.
The San Francisco Giants made MLB history with a remarkable ninth inning against the Milwaukee Brewers that concluded with Mike Yastrzemski's walk-off grand slam.
A regular season home game for a team hovering just above .500 in mid-July was perhaps not a likely setting for one of the most remarkable ever finishes to a major league game.
But it was exactly what the Giants required after the Brewers' five-run fifth inning had turned the contest on its head.
San Francisco were 5-2 down heading into the bottom of the ninth facing All-Star Brewers closer Josh Hader.
What followed was scarcely believable, even for those involved.
Solo home runs from Joey Bart and Darin Ruf were followed by Yastrzemski's big moment, making the Giants the first MLB team to hit three homers in an inning including a walk-off grand slam.
"Three bombs off Hader in the ninth? I still don't believe it," starter Alex Wood said after the dramatic 8-5 win. "It is just crazy. But we needed it and the boys pulled it off."
The Giants could have been forgiven for deeming this a lost cause; their previous walk-off grand slam had come courtesy of Bobby Bonds in September 1973.
But Yastrzemski revealed this stunning late show was inspired by Bart's conversation with injured catcher Curt Casali, which carried through the Giants dugout.
"We felt like the energy was sucked out of the dugout, and I think Joey was just a little fired up that there wasn't any really positive energy at the time," Yastrzemski said. "He was just kind of fed up.
"Obviously, we weren't out of the game, but it kind of felt like it for a little bit. I think we fell into the: 'Here we go again', and I'm glad we were able to flip the script and get out of that."
Bart explained: "I said something to Curt, just between me and him, like: 'Hey, we’ve got to get going'.
"As a young player, I don't feel like it's really my role to try to go and speak out.
"But that's just kind of how I was feeling at the time, like: 'Hey, it's not over yet, let's find a way to win'. And magic happened, for sure."
Andy Farrell believes Ireland have achieved their biggest feat yet by winning a series in New Zealand, a result that he suggests "won't be done again".
The tourists were humbled by the All Blacks in the first of three Tests but responded in sensational fashion with back-to-back victories – their first ever away wins in New Zealand.
A first such series success was secured on Saturday by a 32-22 win in which Ireland dominated the first half and dug in for the second.
And the long-awaited accomplishment is not one Farrell foresees happening again in a hurry.
"This is a special group, you know? To come over here and achieve what they've achieved, it won't be done again," the Ireland coach told Sky Sports. "Knowing what we know, that's not going to happen in the next few years, anyway.
"This is probably the toughest thing to do in world rugby.
"We came over here with task in hand, and we went for it straight from the start, which is great. It's a group of 40 players and a lot of staff, as well.
"We said it was going to be the start of our World Cup year, but I don't know... I think it is probably a little bit bigger than that."
Ireland led by 19 points at half-time, the biggest advantage against New Zealand at that stage of a match in Test history.
Having beaten one of the world's best sides, Farrell's men are confident they can take on any opponents.
"They already do believe that," he said. "They keep turning up and surprising me, certainly. The bunch are just tight, and they really do believe, they really do believe that.
"After the first game, we got held up over the try line five times and made plenty of opportunities in the second game, and they knew there was a better performance in them.
"There certainly was for that first 40, wasn't there? These guys have won a lot of stuff and broke some records – this one will top it, I would have thought."
