Billy Horschel, Matt Kuchar, Scottie Scheffler and Victor Perez are all vying for a spot in the WGC-Dell Technologies Match Play final after a day of upsets in Austin.

Stars Jon Rahm, Tommy Fleetwood and Sergio Garcia surprisingly crashed out in the quarter-finals as the underdogs ruled on Saturday.

The unpredictable tournament continued on the weekend after world number one Dustin Johnson, Justin Thomas, four-time major winner Rory McIlroy, U.S. Open champion Bryson DeChambeau and Patrick Reed were unable to advance beyond the group stage.

Spanish third seed Rahm topped Erik van Rooyen 3 and 2 in the last 16 before being upstaged by Scheffler 3 and 1 in the quarter-finals at the Austin Country Club.

"I felt like I played some really good golf," said Scheffler, who will meet Kuchar in an all-American clash for a spot in Sunday's decider. "I think I kept things bogey-free and I got some early leads and made sure that I kept the pressure on those guys and made them feel like they had to do something special to beat me, which they weren't able to do."

Fleetwood – the 21st seed – succumbed to Horschel after 19 holes, while former Masters champion Garcia was beaten by 31st seed Victor Perez 4 and 3.

American golfer Horschel and France's Perez will do battle in the semis.

Englishman Fleetwood was sent packing after hitting a hole-in-one during his last-16 victory – a drive out of bounds at the 12th seeding him come unstuck in the quarters.

It was a big day for 2013 champion Kuchar, who eliminated former world number one Jordan Spieth 1up before defeating Brian Harman 2 and 1.

Kuchar – the 52nd seed – was runner-up in 2019, with last year's event cancelled due to the coronavirus pandemic.

"Certainly golf's a funny game and I think there are times as a professional where you can feel so far away, you think, golly, I don't have it," Kuchar said.

"I'm racking my brain trying to find it, but then you plug in the right ingredient, the right key, and then all of a sudden it snaps back, and thankfully it's been working and I'm seeing progression. It's just finally now it's clicked and it's a lot more fun this way, I assure you."

LaMarcus Aldridge has agreed to join the star-studded Brooklyn Nets for the rest of the NBA season, according to his agent.

Aldridge – a seven-time All-Star – agreed to a contract buyout with the San Antonio Spurs earlier this month.

Now, the 35-year-old star will join forces with James Harden, Kevin Durant, Kyrie Irving and Blake Griffin in Brooklyn as the Nets eye their first NBA championship.

Aldridge's agent Jeff Schwartz confirmed the deal to ESPN on Saturday.

Averaging 19.4 points and 8.3 rebounds in his 15 NBA seasons, including nine with the Portland Trail Blazers, Aldridge has not played since March 1.

Aldridge is averaging 13.7 points and 4.5 rebounds per game in 2020-21.

Steve Nash's Nets (31-15) are second in the Eastern Conference, one-and-a-half games behind the Philadelphia 76ers (32-13).

Lewis Hamilton claims it is "no secret" the new Formula One regulations have been introduced to slow Mercedes, but he was encouraged by their opening qualifying session of the season.

Changes to aerodynamic regulations for 2021 have had a great impact on the reigning champions' low-rake chassis, the Silver Arrows say.

Mercedes have won the past seven constructors' championships, yet Red Bull led the way in pre-season testing.

The fastest lap belonged to Max Verstappen and the same man took pole on Saturday at the season-opening Bahrain Grand Prix.

But Hamilton was only 0.388 seconds back in second and that performance spells good news for the Briton, with all 16 Bahrain winners coming from the first two rows of the grid but only seven of them qualifying on pole.

Meanwhile, Verstappen has retired three times at this event and four times at the Sakhir track.

Hamilton remains very much in contention, despite feeling the rules have been designed to hurt his team.

"It's no secret. The changes, of course they've been done to peg us back," he said. "We've had the changes last year to our engine to do the same thing.

"That's okay. We love a challenge, we don't look down on these things. We just work hard to do the best that we can, and that's what we'll do."

But Hamilton was not amused by a request for him to analyse where Red Bull are now better, as Verstappen - having ended last year with a win - targets back-to-back triumphs for the first time in his career.

"Really? I don't want to tell you what our problem is," Hamilton said. "They're just faster."

With Silver Arrows team-mate Valtteri Bottas qualifying third, the top three - Verstappen, Hamilton, Bottas - are on course to become the first trio to appear on 15 podiums together.

Although Verstappen is still in the lead, this Mercedes challenge seemed improbable for Hamilton just days ago.

"I think this is a really good step forward for us coming this weekend," he said.

"We thought it was double the gap that you see today. That's down to some really fantastic work from the men and women back at the factory.

"Of course we want to be first, but we knew that it was going to be a challenge, we knew from day one on track really that Red Bull was going to be faster than us.

"We knew we had a bit of an uphill slope to climb. I'm just proud of everyone's efforts."

Elsewhere, two former champions had vastly contrasting fortunes after offseason moves.

Three-time Bahrain winner Fernando Alonso is back in F1 with Alpine Team, formerly Renault, where he won two world titles.

And his second debut was a success as he reached Q3 for the first time since Monaco 2018 and claimed ninth on the grid.

"It was good," said Alonso, who won this event on the previous two occasions it opened a season. "I think we have to be pleased with the qualifying.

"I was not confident in any of the sessions so far in the weekend - I was struggling a little bit to feel the rear of the car in windy conditions - and now in the qualifying everything was calmer.

"The night situation I think helped us with the cooler temperatures, so I was able to attack and feel the car a little bit better and it was fun."

On the other hand, Sebastian Vettel was eliminated in Q1 as his second run was hampered by yellow flags prompted by Haas rookie Nikita Mazepin's spin.

No driver has more wins (four) or poles (three) in Bahrain than the former Ferrari man, but his Aston Martin bow did not go to plan.

Vettel will start from 18th and said: "If I panicked now, would it help? If I was really upset?

"For sure, I am upset and angry that it wasn't our fault in a way not to make it through, but we have to take it and do what we can, preparing tomorrow."

Matters could yet get worse for the German, who will appear before the stewards on Sunday for failing to respect the flags, potentially meaning a five-place penalty.

Francesco Bagnaia targeted "a really great result" at the Qatar Grand Prix after setting a stunning lap record on his factory Ducati debut.

Third-year MotoGP rider Bagnaia had finished 15th and 16th in his two seasons with Pramac Racing but has quickly focused on loftier ambitions following his bow with the factory team.

Ducati - winners of the previous two Qatar GPs with the since-departed Andrea Dovizioso - had been fast all week at the season opener, with Jack Miller setting the practice pace in his 100th grand prix with a best time of one minute and 53.387 seconds ahead of second-placed team-mate Bagnaia.

But Bagnaia later suggested he had believed he could run in less than 1:53 in qualifying and so it proved, a magnificent 1:52.772 setting a two-wheel lap record at the Losail International Circuit.

That was enough for a healthy 0.266-second gap to Fabio Quartararo, while Bagnaia gave veteran Valentino Rossi - a four-time Qatar winner - a tow to take him to the front of the second row.

Rossi has 10 podiums at Losail and his next in MotoGP will make him the first to 200.

Even from his commanding position, Bagnaia could be forgiven for being pessimistic after his year-high six abandonments in 2020 - including five in the final eight races - but he was full of positivity following an outstanding display.

"I'm very happy," he said. "Already yesterday I was thinking it was possible today to arrive at (1:)52.

"In the second attempt, when I started pushing, I thought it was possible. After the third sector, I was very close to this lap time.

"I'm very happy; my first pole position in my first race with this team. I would like to make everything possible to finish the race tomorrow in the best way possible. I think we can make a really great result."

Miller had to settle for fifth, next to Rossi, as he pursues a third straight podium for the first time in his career following two to end 2020.

Quartararo also had reason to be disappointed with his day as he mistimed his second run and the chequered flag denied him the opportunity to challenge Bagnaia.

Another debutant at a factory team, Yamaha's Quartararo won the first two races of the season last year but has had only one podium in 12 outings since.

The 21-year-old, who has colleague Maverick Vinales - the 2017 Qatar winner - behind him in third, said: "It's a shame I couldn't do the second lap on my second run. I had the chequered flag for a second.

"But I'm quite happy. I think we did a great lap. We tried something in FP4 that was bad, honestly - I didn't feel great on the bike. But I feel that we have great potential for tomorrow.

"We will go with that bike for the race because it's the one that I feel good [on]. I think we made too much changes today, but I'm feeling happy.

"I think we did a great, great job in the qualifying. Now we're just missing the race. I can't wait."

Neither the Ducatis nor the Yamahas should have to worry this weekend about defending champion Joan Mir, who failed to capitalise on the absence of Repsol Honda great Marc Marquez.

Mir was forced to contend in Q1 and will start from 10th, having finished eighth in his only previous Losail entry in 2018.

Lewis Hamilton felt he had got all he could out of his Mercedes as Max Verstappen stormed to an impressive pole position for the season-opening Bahrain Grand Prix.

Red Bull driver Verstappen finished 0.388 seconds clear of Mercedes rival and defending world champion Hamilton in qualifying on Saturday.

Valtteri Bottas was 0.589s back in third with Charles Leclerc taking an impressive fourth for Ferrari.

Verstappen had previously topped every practice session in Sakhir, a circuit where he is due a change of luck having retired there four times – more than at any other track in his Formula One career.

His dominant start to the campaign has fans dreaming of a competitive 2021 season after Hamilton was in a class of his own in winning a seventh world title last year.

"We have already had a great week of testing," Verstappen said.

"There are no guarantees but it's been great so far coming back for the race week. The car has been working really well - really enjoyable to drive.

"With the wind conditions changing, it's not easy to change the set-up of the car for every session but it all worked out perfectly in qualifying and I'm really happy with pole position.

"My first lap in Q3 wasn't amazing so I knew there was more in it – you never know how much - but finally the balance was there and you can push a little bit more. 

"You have to be careful not to overheat the rear tyres but where it mattered we could perform. The car has been steady on the short and long runs - we have a good car."

Hamilton felt grid spots of second and third were solid accomplishments for Mercedes after their struggles in pre-season testing.

The Briton said: "Amazing [to have competition]. Congratulations to Max. He did such a great job, so fast on that last lap.

"I absolutely gave it everything I had but unfortunately it was not good enough. There is always more but it was the best I could do that is for sure and I got absolutely everything I could from the car.

"We did a really good job from testing to come here - everyone in the factory has done an amazing job. 

"To be that close, closer to the Red Bulls [is good] considering in testing we thought we would be further behind."

There was some disappointment for Red Bull when Sergio Perez was unable to reach Q3 as he tried to reach the shoot-out on medium tyres. He will start 11th.

It means Hamilton and Bottas will, as they did for much of last season when Alex Albon struggled, have a strategic numerical advantage at the front as they battle Verstappen.

Bottas said: "Anything is possible and we can only aim for Sunday. We have two cars in the mix at the front with Max, so we'll see.

"The practice this morning wasn't easy, I had a couple of issues with balance.

"It was a bit better this evening. We used two sets of soft tyres in Q2 so in Q3, I only had one set of tyres, so it wasn't easy to compete with Max and Lewis."

Verstappen was just 0.023s ahead of Hamilton after the first runs of Q3, and then had to respond when his rival went fastest with his second attempt.

The Dutchman produced a brilliant answer, though, comfortably taking pole as he looks to win two straight races for the first time in his F1 career, having triumphed in the last race of 2020.

Pierre Gasly was fifth ahead of Daniel Ricciardo for his new team McLaren. Lando Norris, Carlos Sainz, the returning Fernando Alonso and Lance Stroll rounded out the top 10.

Sebastian Vettel had a frustrating first competitive outing for Aston Martin, as he and Esteban Ocon were eliminated in Q1, not helped by yellow flags towards the end of the session.

Ocon was 16th with Vettel in 18th, just one place ahead of Mick Schumacher on his F1 debut as the two Haas cars finished on the back row.

Hamilton has won the last two editions of the Bahrain Grand Prix, but no driver has ever recorded three straight victories at the event.

PROVISIONAL CLASSIFICATION

It was not sealed in the fashion they would have hoped for, but Wales could belatedly celebrate Six Nations glory on Friday.

Wayne Pivac's side had missed the chance to claim a Grand Slam triumph last week in a heartbreaking last-gasp defeat to France.

But with France needing a bonus-point win by a 21-point margin in Friday's rearranged clash with Scotland - delayed due to an earlier COVID-19 outbreak - to deny Wales again, Les Bleus' loss in Paris handed them the title.

"It's a real emotional rollercoaster, the last seven days really," Wales head coach Pivac said on Saturday.

He added: "It was just different and that's what we've come to expect from this pandemic really.

"It was evident that we had to go and do something different and that was to watch us win a championship from our living room."

That was far from the only first in a tournament with its fair share of twists and turns, though, as Opta data shows.
 

MORE TRIES, MORE DRAMA

There were six tries in Friday's frantic affair at the Stade de France and that contributed to a new Six Nations record.

A total of 86 tries were scored across the 15 matches, the most in a single edition of the tournament in its history.

And Scotland's dramatic 27-23 success, sealed with an 80th-minute Duhan van der Merwe score, was a fitting end to the competition.

Eight of the 15 games were decided by margins of five points or fewer, another new benchmark.

"There were some great games," Pivac said. "It was just a shame we didn't have crowds. You can imagine how much of an atmosphere would have been generated.

"It was a good advertisement for the game and a lot of nations are heading in the right direction. It's exciting."

Van der Merwe beat two defenders in the decisive fixture and in doing so set a new tournament high of 31, surpassing Brian O'Driscoll's 30 defenders beaten in 2000.

The wing's brace also saw him become the first Scotland player to finish a Six Nations campaign as the outright leading try scorer (five).

France needed to score at least one more try in order to have a chance of snatching the championship, but they still matched their best haul of 18 from 2006.

Not all the records were quite so impressive.

Italy conceded 239 points, 34 tries and had a points difference of -184, the worst such tallies for any team in an edition of the Six Nations.
 

CHANGING OF THE GUARD

Wales' title was their sixth since Italy were introduced to the tournament to form the Six Nations in 2000.

Four of their previous five had been Grand Slam successes, a record over this period they could not extend thanks to France's epic win last week.

But Wales are now only one Six Nations crown behind England's seven.

"It gives us a lot of confidence to feel like we're on the right track," the title-winning coach said. "We can't get ahead of ourselves."

This was not a tournament England will reflect on fondly, even as captain Owen Farrell became only the third man - after Ronan O'Gara and Jonny Wilkinson - to reach 500 points in the Five/Six Nations.

Eddie Jones' outfit came in as defending champions but slumped to their joint-worst Six Nations finish, coming fifth as they had in 2018.

England also lost against Ireland, Wales and Scotland in the same Five/Six Nations campaign for the first time since 1976.

At the bottom of the table, though, there was no change.

Italy have picked up the Wooden Spoon in each of the past six years, this after finishing bottom of the championship just once in the prior four seasons.

Simona Halep has withdrawn from the Miami Open due to a shoulder injury.

Halep beat Caroline Garcia in the second round in Florida on Thursday, but an issue with the world number three's right shoulder prevented her from facing Anastasija Sevastova.

The two-time grand slam champion said: "I'm very sorry to I have to pull out of the singles and doubles at the Miami Open, but my injury doesn't let me play here as expected.

"I'm sad that I can't continue, I wanted to come here to give my best and play many matches but unfortunately I can't. 

"Hopefully next year I will come back healthy and better."

Sevastova will face either French Open champion Iga Swiatek or Ana Konjuh in the round of 16.

The Reds thrashed Waratahs 46-14 to maintain their perfect start to the Super Rugby AU season and return to the top of the standings.

Substitute Alex Mafi's second-half hat-trick helped seal an emphatic victory for the leaders, who had not beaten the Waratahs in Sydney in eight years.

Will Harrison kicked three penalties for the hosts in the first half, but the Reds responded through tries from Tate McDermott, Lukhan Salakaia-Loto and Filipo Daugunu.

Taniela Tupou crossed over early in the second half to extend the Reds' lead and, while Will Harris touched down to give Waratahs a temporary reprieve, their opponents soon ran away with the game.

Mafi, brought on at the interval, scored the first of his three tries with a little over an hour played and added two more before full-time, either side of Hugh Sinclair and Zane Nonggorr being sin-binned for separate offences.

The Super Rugby Aotearoa clash between Chiefs and Blues earlier on Saturday was a lot tighter, with Damian McKenzie snatching a famous 15-12 win for the hosts in the final minute.

Akira Ioane found a way through 24 minutes in for the only score of the first half of what turned out to be a thrilling contest in Hamilton.

But the Chiefs, who had gone 11 matches without a Super Rugby win before beating Hurricanes last weekend, hit back through McKenzie's penalty and a Samisoni Taukei'aho try, the hooker grounding the ball in the midst of a maul of players.

That lead lasted just a few minutes, however, as Tom Robinson charged clear and dotted down for the Blues' second try, which Otere Black was unable to add to from the conversion.

And that would prove a costly miss as, with less than a minute to go, McKenzie rounded off a fine counter-attack and brushed himself down to add the extras for a memorable victory that lifts Chiefs up to third, now within two points of their opponents.

James Harden says he feels like the MVP of the NBA following his latest dominant display in the Brooklyn Nets' 113-111 win over the Detroit Pistons on Friday.

Harden returned from neck soreness to score 44 points for the Nets, his largest haul since joining Brooklyn from the Houston Rockets in January.

He also contributed 14 rebounds and eight assists in a decisive performance.

"I feel like I am the MVP," Harden said. "I don't want to speak individually on myself. I'm just going to leave it at that.

"I just try to go out there every single night and bring my team-mates everything I can."

The 31-year-old guard, who averages the most minutes per game in 2020-21, tops the statistics for assists per game this season, with 11.2. He is also averaging 25.3 points and 7.9 rebounds.

Denver's Nikola Jokic, Philadelphia's Joel Embiid, Milwaukee's Giannis Antetokounmpo and Lakers star LeBron James are among the favourites to win the MVP along with Harden.

Harden added: "Tonight, Detroit's game plan and schemes were to take away the lob pass and not let our bigs get lobs and shooters to get shots.

"That allowed me to get to the basket and shoot layups all night. Games are different and I just take what the defense gives me. The next game we might get more lobs than shots.

"Just play the game the right way and try to be efficient in doing it."

Third seed Alexander Zverev was sensationally dumped out of the Miami Open second round as Finnish 21-year-old Emil Ruusuvuori claimed his second top 10 win of his career.

Russuvuori bounced back after losing the first set, changing his tactics and overwhelming the German on Friday to set up a third round meeting with Mikael Ymer.

Ninth seed Grigor Dimitrov also bowed out, going down to Briton Cameron Norrie, while eighth seed David Goffin lost to James Duckworth.

World number two and top seed Daniil Medvedev eased past Lu Yen-hsun, while 11th seed Felix Auger-Aliassime, Karen Khachanov and John Isner all progressed.

TURNAROUND STUNS THIRD SEED

Zverev may have won last week's Mexican Open and the opening set 6-1 against Ruusuvuori but the tables turned quickly as the Finn produced one of the best displays of his career to date.

The 83rd ranked Finn moved regularly to the net and was aggressive in his approach, leaving Zverev rattled before winning 1-6 6-3 6-1 in a stunning momentum shift.

"I don't even know myself," Ruusuvuori said in his on-court interview when asked how he turned the match around.

"I wasn't feeling very comfortable in the first set and I was making a lot of unforced errors but slowly in the second I was starting to feel a bit better... Of course, it's one of the biggest wins in my career so it feels good."

He'll next face Ymer who knocked out 27th seed Nikoloz Basilashvili.

NINTH SEED BUNDLED OUT

Former world number three Dimitrov was ousted from the Miami Open on Friday, losing 7-5 7-5 to 56th ranked Norrie.

The Bulgarian took an early break and served for the first set at 5-3 but Norrie showed his mettle to break back twice to take the opener.

Norrie sent down 10 aces and was strong on serve throughout, claiming a significant win for his burgeoning career.

“It’s huge,” Norrie said. “He’s had a good start to the year. It was such a physical match at the start. He came out really fast and he set the tone at the beginning of the match. Massive one for me and I take a lot of confidence from it.”

Norrie's win sets up a third round meeting with American Taylor Fritz who beat Marcos Giron 6-2 6-2.

DANIIL DOMINATES, GOFFIN SHOCK

Australian Open runner-up Medvedev made light work of Lu, winning 6-2 6-2 to book a third round match with Australian 21-year-old Alexei Popyrin.

Medvedev won in less than an hour, hitting 24 winners and nine aces and making few errors in a clinical display.

Canadian 11th seed Aliassime proved too good for Pierre-Hugues Herbert 6-4 6-4, setting up a third round meeting with 18th seed John Isner who got past qualifier Mackenzie McDonald.

Seventh seed Roberto Bautista Agut progressed by virtue of a walkover against Lloyd Harris who had a wrist issue.

Eighth seed Goffin lost to world number 104 Duckworth 6-3 6-1 in a boilover.

Second seed Naomi Osaka picked up where she left off at last month's Australian Open, winning her first match since lifting the title in Melbourne.

Osaka earned her place in the Miami Open third round on Friday with a hard-fought straight-sets victory over Australian Ajla Tomljanovic.

Australian Open runner-up Jennifer Brady was knocked out in the second round by 58th-ranked Sara Sorribes Tormo.

Brady's defeat was the major surprise on Friday, with Sorribes Tormo fighting back from a set down to win.

Top 10 seeds Karolina Pliskova, Bianca Andreescu and Sofia Kenin also progressed, with the latter coming from a set behind to beat Andrea Petkovic.

OSAKA CONTINUES WINNING RUN

Osaka extended her winning streak to 22 matches, although it was not easy against Tomljanovic.

The Japanese got the edge 7-6 (7-3) 6-4, firing down 36 winners, including 13 aces in a match lasting one hour, 38 minutes.

"This is my first match since Australia, so I just really wanted to play well," Osaka said in her on-court post-match interview. "I kind of feel like I'm at home here, because I grew up [near here] for most of my life."

Tomljanovic did not go down without a fight but was let down by 24 unforced errors.

Osaka will next face Serbian qualifier Nina Stojanovic in the third round.

BRADY BEATEN AGAIN

World number 14 Brady succumbed to in-form Monterrey Open semi-finalist Sorribes Tormo 3-6 6-4 6-1.

Brady had a dream run to the final at the Australian Open last month but came back to earth with a thud against the Spaniard, who has won 10 of her past 11 matches.

The match lasted two hours, 22 minutes, with Sorribes Tormo finding the edge in the last as Brady's first-serve percentage dropped to 30.8 per cent.

Brady's defeat comes a few weeks after being humbled by Anett Kontaveit in less than an hour in the Qatar Open first round.

MIXED BAG FOR SEEDS

Tenth seed Kiki Bertens, in her third match back from Achilles surgery, was knocked out by Russian qualifier Ludmilla Samsonova 6-2 6-1 inside an hour.

Fourth seed and last year's Australian Open champion Kenin responded after losing the first set to defeat Andrea Petkovic, winning 6-7 (6-8) 6-1 6-3. The match was Kenin's first since appendix surgery.

Sixth seed Pliskova comfortably got past Zheng Saisai 6-2 6-1 and 2019 US Open champion Andreescu triumphed over Tereza Martincova 7-6 (7-5) 6-2.

Seeds Elena Rybakina, Kontaveit, Maria Sakkari, Ons Jabeur and Amanda Anisimova all won, with 20th seed Petra Martic and Sloane Stephens both knocked out.

Dustin Johnson, Justin Thomas and Bryson DeChambeau were among those to pack their bags as the field was cut to 16 at the WGC-Dell Technologies Match Play on Friday.

Top-seeded Johnson lost to Kevin Na, who finished birdie-birdie to turn the match and eliminate his fellow American from Group 1 on day three in Austin.

Scotland's Robert MacIntyre progressed out of the group after a tie with Adam Long, having landed one of the shots of the week with a spectacular drive on the 18th which ended up inside three feet and ultimately got him through.

"I had probably one of the best and one of the luckiest golf shots I've hit in my life," the Scot said.

"I had a bit of bad luck here and there and managed to turn it around right at the end there, and it's one of them things, you've just got to keep fighting until the end, and it just shows anything can happen in this game."

Johnson and Na's match was not without tension, with the 28th-seeded American tapping his opponent on the shoulder on the 11th green to warn him about collecting his ball before concession had been verbalised.

In a mildly tense exchange, Johnson appeared to apologise but walked away less than impressed.

DeChambeau, the fifth seed, bowed out at the hands of Tommy Fleetwood, who topped Group 5.

Fleetwood had established a 4up advantage through seven holes but stumbled, allowing DeChambeau back in the match. The Englishman finished with a par on the 18th to win.

"It turned really scrappy for a lot of the back nine," Fleetwood said. "He started coming back and on the last an unlikely par. Match Play is that funny all week. There are guys who have played better than me for three days who are going home and I'm going through."

World number two Justin Thomas was another casualty, despite defeating 2010 Open champion Louis Oosthuizen 3 and 2.

There were eight playoffs required, with Jon Rahm, Bubba Watson and Sergio Garcia among those winning to join the likes of Jordan Spieth in the last 16.

Garcia delivered an incredible shot to beat Lee Westwood, making a hole-in-one at the fourth hole.

Rory McIlroy was also eliminated, tying with Cameron Smith as Ian Poulter finished top of Group 11 after three wins.
