A weather delay gave Augusta leader Justin Rose time to reflect on a mixed start to Saturday's play at The Masters.

Rose had led by four strokes after the first round but saw that advantage cut to a single shot on Friday, with Will Zalatoris and Brian Harman his closest challengers.

The one-time major champion was last out on moving day but quickly set about restoring a healthy lead.

Indeed, birdies at the first two holes had Rose three clear at nine under, yet this hot streak did not last.

Rose found the bunker at four and could only rescue a bogey, before befalling the same fate at the fifth, the sand contributing again.

The Englishman recovered with par at the sixth and had just played a solid tee shot at seven when an official approached and sounded the horn to signal an imminent storm.

As play was suspended, Rose was again one ahead of Zalatoris, who was joined at six under by Marc Leishman.

Corey Conners was the day's big mover to that point, in a tie for fourth after playing 11 holes at three under.

Conners' hole in one at the par-three sixth was the highlight, coming straight after the first of two bogeys.

Justin Thomas and Hideki Matsuyama - both one under for the day - were level with Conners, while Harman was back at four under following three bogeys and a birdie through seven.

Jordan Spieth's challenge faltered, although a superb birdie brought him back level with Harman after a double-bogey at seven had threatened to knock him out of contention entirely.

Patrick Reed - two under on Saturday and one under for the week - and Phil Mickelson - three under to reach even par - were among those to complete their rounds before the weather hit.

Justin Rose mounted a back-nine recovery to finish his second round with a two-shot lead over Jordan Spieth and Marc Leishman.

Rose shot a sublime opening round of 65 at Augusta, but relinquished his four-shot advantage on Friday before returning to the top of the leaderboard with three birdies in his space of four holes.

The Englishman was the man to catch on seven under when he signed for a level-par 72, rallying after bogeying four of the first seven holes in his second round.

Gains at the 13th, 14th and 16th holes gave Rose momentum heading into the weekend as he bids to don the green jacket for the first time.

The in-form Spieth surged into a share of second place with Australian Leishman by carding a four-under 68, with birdies proving easier to come by for the field than on the opening day.

Three-time major champion Spieth, on a high after ending a title drought stretching back to 2017 at the Texas Open last weekend, made four of his five birdies after the turn and only dropped one shot at the 12th.

Leishman also made a significant move, setting the tone by starting with three birdies in row and going on to shoot a five-under 67.

Scintillating six-under rounds of 66 from Bernd Wiesberger and Tony Finau put them just three shots adrift of Rose along with Justin Thomas, who shot a 67.

Will Zalatoris, Brian Harman and Si Woo Kim were also well poised on four under, with their rounds still in progress. Defending champion Dustin Johnson had work to do back on three over through 10.

Bryson DeChambeau responded to a poor opening round with a 67 of his own to sit at one over, while Brooks Koepka (+5) and Rory McIlroy (+6) were facing a battle to make the cut 10 and eight holes into their rounds respectively.

Lee Westwood was a couple of shots below the projected cut mark on five over midway through his round.

Justin Rose surged into a four-shot lead as Rory McIlroy and Bryson DeChambeau were among the big names to endure first-round struggles at The Masters.

Rose was two over through seven holes in tough scoring conditions, with quicker and firmer Augusta greens proving a much bigger challenge than when Dustin Johnson won the tournament with a record score of 20 under last November.

The Englishman sparked into life with an eagle at the par-five eighth hole and lit up the back nine to card a magnificent seven-under 65, the lowest Masters round of his career, with patrons allowed back in under blue skies.

Rose, eyeing a maiden Masters title, got on a roll with seven birdies in nine holes before finishing with a composed par to retain his four-stroke advantage.

Brian Harman and Hideki Matsuyama shared the early clubhouse lead with impressive three-under opening rounds of 69 before Rose stormed clear.

Defending champion Johnson shot a two-over 74 following a double bogey at the 18th, having made a bogey-birdie start before getting in the red for the first time at 13.

Masters debutant Will Zalatoris, Webb Simpson, Christiaan Bezuidenhout and Patrick Reed will start their second rounds on two under following encouraging starts, while new father Jon Rahm and Xander Schauffele are among a clutch of players at level par.

McIlroy suffered a miserable opening round and is back on four over, facing a battle to make the cut rather than fight it out to complete a career Grand Slam, while U.S. Open champion DeChambeau was four over through 15.

Jordan Spieth was left to rue a triple-bogey after launching a wayward tee shot into the trees at the ninth but was in a share of eighth on one under after chipping in for an eagle at 15, while Justin Thomas was a further stroke back through 15.

Brooks Koepka matched Johnson's 74 just a few weeks after undergoing knee surgery and the previously in-form Lee Westwood is languishing on six over.

Tommy Fleetwood generated a roar from those fortunate enough to be at the 16th to see him make a hole-in-one before he signed for a 74.

Tiger Woods is "bummed" to be missing The Masters after his car crash in February, friend and practice partner Justin Thomas has revealed.

Five-time Augusta champion Woods will be watching from home this week rather than taking to the course he knows so well.

The golf great was involved in a single-vehicle incident six weeks ago that saw his car roll "several hundred feet".

Woods required surgery on serious leg injuries, while an officer from the Los Angeles County Sheriff's Department said in the aftermath the 45-year-old was "very fortunate" to survive.

It was just the latest setback in a superstar career and means Woods is absent from The Masters for the fourth time in eight years, although he did win the tournament in 2019.

There had been appearances from Woods at each of the prior 19 editions of The Masters, while he was the last man to retain the green jacket with back-to-back triumphs in 2001 and 2002 and is one of only five to have celebrated a career Grand Slam, this week marking 20 years since his 'Tiger Slam'.

Woods posted on Twitter on Tuesday: "I'll miss running up @DJohnsonPGA's bill at the Champions Dinner tonight. It's still one of my favorite nights of the year."

Thomas, who regularly practises with Woods and Fred Couples ahead of the Augusta major, said at a news conference: "I went over and saw him a couple times last week and try to go over a couple times during the week whenever I'm home and see him.

"We texted Friday morning, and he said it's kind of starting to set in. He's bummed he's not here playing practice rounds with us, and we hate it, too.

"I'm very, very lucky that I somehow got thrown into that practice-round group with Tiger and Freddie the last four years or whatever it is, especially around this place.

"I just follow them around like puppy dogs. Wherever they go, that's where I go after it. If they hit chips from somewhere, I go hit chips from there.

"It's no coincidence they have been so successful here, but they are also just great guys to be around. I definitely miss that part."

Thomas added: "[Couples] didn't feel like getting up in the early cold weather this morning, so I made sure to give him some grief.

"I don't know if he would have bailed on me if Tiger was with me, but he did on me."

Couples posted on his own Twitter page: "Thinking of my guy @tigerwoods during this week @themasters. I'll miss you tonight at dinner. Not the same without you."

Thomas, who has improved his Masters finish every year since his 2016 debut and came fourth last year, has been grouped with Tony Finau and Louis Oosthuizen for a 13:48 EDT start on Thursday.

Couples will play with Francesco Molinari and amateur Charles Osborne, teeing off at 12:24 EDT.

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.

Rory McIlroy and Bryson DeChambeau stayed alive at the WGC-Dell Technologies Match Play, where world number one Dustin Johnson showed why he is golf's top-ranked player.

McIlroy extended his campaign at the Austin Country Club with a confidence-boosting 4 and 3 win over Lanto Griffin on Thursday.

Four-time major champion McIlroy endured a forgettable opening day in Austin on Wednesday, playing a tee shot into a swimming pool during a shocking 6 and 5 humbling at the hands of Ian Poulter.

But McIlroy – who missed the cut at The Players Championship – bounced back on day two, though the Northern Irishman still has his work cut out in the round-robin group phase after Poulter defeated Cameron Smith.

In order for McIlroy to advance from Group 11, the former world number one must beat Smith in the final match while also requiring leader Poulter to lose to Griffin.

"That was big," said McIlroy. "Obviously winning the match today keeps me in the tournament and gives me hope for tomorrow. It looks like Lanto is going to have to do me a favour and beat Poults.

"I hit a couple of destructive shots yesterday, but overall both of us played well, and I didn't feel the scoreline matched up with how I felt like I played. And then the same thing today. I played solid. Lanto didn't have his best stuff, but I played solid and kept it in play and holed some good putts when it mattered."

U.S. Open champion DeChambeau also breathed life into his campaign as the American star narrowly avoided elimination.

After suffering an upset at the hands of unheralded Frenchman Antoine Rozner on day one, DeChambeau was forced to dig deep against Kim Si-woo.

Down one, fifth seed and Arnold Palmer Invitational winner DeChambeau prevailed 2 and 1 after Kim's tee shot on 17 found the penalty area.

DeChambeau needs to beat Group 5 leader Tommy Fleetwood to have a chance to qualify for the weekend.

Top seed Johnson flexed his muscles as he came from behind to deny rising star Robert MacIntyre.

MacIntyre was on the verge of a prized scalp before Johnson rallied to tie the Group 1 showdown, having been two down with two to play.

The pair have one and a half points from two matches heading into their final matches.

World number two and Players Championship winner Justin Thomas, meanwhile, crashed out following a 2 and 1 defeat to defending champion Kevin Kisner.

Rory McIlroy played a tee shot into a swimming pool during a shocking start to his WGC-Dell Technologies Match Play campaign, where he was hammered 6 and 5 by Ian Poulter.

The Northern Irishman has had well documented issues with his swing in recent weeks and has linked up with renowned coach Pete Cowen for the tournament at the Austin Country Club.

But McIlroy struggled badly during his round-robin opener against fellow Europe Ryder Cup star Poulter and was already two down by the time he pulled his tee shot wildly left at the fifth tee, with his ball sinking into the pool at a nearby house.

He managed to claw within one by the eighth, but Poulter then won five holes in a row to condemn McIlroy to a heavily opening defeat in Group 11, where Cameron Smith beat Lanto Griffin in the pool's other opener.

Dustin Johnson had no such woe as he started with a 2 Up win over Adam Long in Group One, while Jon Rahm defeated Sebastian Munoz 1 Up (Group 3), and Bryson DeChambeau overcame Antoine Rozner 2 Up (Group 5).

Justin Thomas was beaten 3 and 2 by Matt Kuchar (Group 2), though, while Jordan Spieth outclassed Matthew Fitzpatrick 3 and 1 (Group 15) despite a comedy moment when he drove the 15th green…but from the 13th tee.

Collin Morikawa added the WGC-Workday Championship to his growing list of achievements after triumphing by three strokes.

Winner of last year's U.S. PGA Championship, Morikawa used a three-under-par 69 to seal victory at the star-studded World Golf Championships event in Florida ahead of Viktor Hovland, Brooks Koepka and Billy Horschel on Sunday.

Morikawa holed four birdies and just one bogey to finish 18 under for his fourth PGA Tour crown – the most by any player currently aged under 25.

He also joins Tiger Woods as the only player to win a major championship and WGC event before turning 25.

Further to that feat, Morikawa is the seventh player to claim four or more PGA Tour tournaments – including a major – under the age of 25, following in the footsteps of Woods, Jack Nicklaus, Jordan Spieth, Rory McIlroy, Justin Thomas and Jerry Pate.

The overnight leader by two strokes, Morikawa recovered from a slow start after bogeying his second hole of the final round – the 24-year-old American birdieing three of five holes before the turn as he ended the day without dropping another shot.

Norwegian star Hovland mounted a serious title charge following a five-under par 67, but he was unable to stop Morikawa.

Hovland finished tied for second alongside four-time major champion Koepka (70) and Horschel (70) at The Concession Golf Club.

McIlroy's final-round 71 saw the former world number one and four-time major winner slip down into a tie for sixth, six strokes adrift of Morikawa.

Defending champion Patrick Reed (72) ended the co-sanctioned PGA and European Tour tournament a shot further back.

Justin Thomas (71) earned a share of 15th at eight under, a stroke better off than U.S. Open champion Bryson DeChambeau (69).

It was a forgettable finish for world number one Dustin Johnson, who closed proceedings with a six-over-par 78.

The two-time tournament winner plummeted 12 positions to T54 at five over the card.

Brooks Koepka fired a six-under 66 to grab a one-stroke lead at the halfway mark of the WGC-Workday Championship.

The four-time major champion made seven birdies and one bogey at The Concession Golf Club in Florida on Friday to move into 11 under.

Koepka holds a 36-hole lead or co-lead on the PGA Tour for the eighth time in his career as he eyes a second World Golf Championships title.

The American made three straight birdies from the 15th before dropping his only shot of the round at the last.

Koepka is a stroke clear of Collin Morikawa (64), Billy Horschel (67) and Australian Cameron Smith (66).

Morikawa, last year's US PGA Championship winner, produced the equal best round of the day, with Bryson DeChambeau – who is tied for 20th – also shooting a 64.

Overnight leaders Webb Simpson and Matt Fitzpatrick both slipped back into a tie for fifth after firing 69s, sitting at nine under alongside Tony Finau (67).

Defending champion Patrick Reed carded another 68 to be at eight under alongside Kevin Kisner (69).

Rory McIlroy shot a two-under 70 to get to five under and into a tie for 13th, with Justin Thomas (66) also among that group.

A six-time WGC winner, Dustin Johnson improved on his opening-round 77, carding a 69 that sees him sitting at two over.

Sam Burns pulled five strokes clear at the halfway mark of the Genesis Invitational, while Dustin Johnson is among the chasing pack.

Burns, 24, carded a five-under 66 in the second round at Riviera Country Club in California to surge clear at 12 under on Friday.

Seeking a first PGA Tour win, Burns – who held a two-shot overnight lead – produced a bogey-free second round that included five birdies.

With his total of 130, Burns tied the 36-hole record at the tournament with three players – Davis Love III (1992), Mike Weir (2004) and Shigeki Maruyama (2004).

Johnson, the 2017 champion, is in a four-way tie for second at seven under after shooting a 67.

The two-time major winner recovered from a bogey at the second hole to post five birdies and sit alongside Tyler McCumber (68), Jason Kokrak (68) and Joaquin Niemann (68).

Jordan Spieth continued his good form with a second straight 68 seeing him at six under and in a tie for sixth.

Coming off back-to-back top-five finishes, Spieth is alongside Max Homa (70) and Wyndham Clark (69), while Alex Noren (70), Scott Harrington (66), Cameron Smith (68), Patrick Cantlay (70) and Matt Fitzpatrick (71) are a shot further back.

Brooks Koepka carded a 70 to be at four under, while Rory McIlroy and 2019 runner-up Justin Thomas both missed the cut.

McIlroy missed the weekend at an event for the first time since the 2019 Open Championship after finishing at seven over.

Justin Thomas insists his "embarrassing" and "humiliating" use of a homophobic slur is "not me" and reflected on Ralph Lauren's decision to stop working with him as a result of the incident.

World number three Thomas was heard making the offensive comment by a television microphone when playing at the Tournament of Champions in Hawaii earlier this month.

Afterwards, Thomas apologised for his "inexcusable" use of the slur and he again addressed the issue when previewing the Abu Dhabi Championship on the European Tour this weekend. 

"It's humiliating. It's embarrassing. It's not me. It's not a word that I use, but for some reason, it was in there," Thomas said. 

"And that's what I'm trying to figure out as to why it was in there, and just like I said, it's going to be a part of this process and training program or whatever I need to do, not only to prove to myself but prove to my sponsors and prove to those people that don't know who I am that that is indeed not the person I am."

Thomas will be playing without shirt branding in Abu Dhabi after Ralph Lauren opted to end its partnership with the 27-year-old.

Asked about the company's decision, Thomas replied: "I think disappointed is the wrong word. 

"Obviously I was upset. But at the end of the day, they have that right. They had to make the decision that they had to make. I spoke with them along with all my sponsors. 

"Although I apologised, it's like it was then; it's an opportunity for me to grow and I felt like it was something we could have done together and gone through that process. 

"They just felt like they needed to move on. That's exactly what I'm doing, as well. It was a great run that we had and a great partnership, but you know, things will work out on the best."

Thomas confirmed conversations have been held with his other sponsors, adding: "I've had great communication with all of them. 

"It was obviously not calls or e-mails I was hoping or planning to make but I needed to because I have some great long-lasting partnerships with all my sponsors. They know that's not the person that I am.

"They know that's not how I act and although they are far from brushing it to the side just like I am, they understand that this is an opportunity for me to educate myself, grow, become a better person, and just like they hope, I know that I'll become a better man and a better person because of it, and they are going to kind of help me along that process."

Thomas earned the backing of Rory McIlroy, who is confident his on-course rival will learn from his error in judgement.

"I think he's already responded really, really well," the four-time major winner said. 

"I think he realised he made a big mistake as soon as it was brought to him and he completely owned up to it. He said he messed up; he's going to try to be better. 

"And you know, Justin is true to his word. He will be. If anything, it will probably just make him a better person than he already is, which is hard because he's already a great guy."
