Patrick Cantlay defeated Collin Morikawa in a play-off to win the Memorial Tournament on Sunday.

Cantlay earned his second Memorial title, having also won the tournament in 2019, after Morikawa was unable to match his par putt on the first play-off hole.

A sudden-death shoot-out was needed at Muirfield Village Golf Club after Cantlay and fellow American Morikawa finished 13 under through 72 holes following final-round 71s.

It became a showdown between Cantlay and Morikawa on the final day after runaway leader Jon Rahm was forced to withdraw following a positive coronavirus test.

Defending champion Rahm was six shots clear of Cantlay and Morikawa in the third round before the duo were thrust to the top of the leaderboard.

"It's such a weird situation and so unfortunate because, me included, everyone knows it would be a totally different day today had that [Rahm's withdrawal] not happened," Cantlay said after his fourth PGA Tour triumph.

"There's nothing I can do about it and I just tried to work as hard as I could to reset and really get focused.

"I started off a bit shaky today but I really hit a lot of good shots coming in and it felt the same as when I won a couple of years ago. I felt calm and collected and it worked out."

Scottie Scheffler (70) finished two shots behind Cantlay and Morikawa, while Branden Grace (71) was a stroke further back as Patrick Reed and his three-under-par 69 earned him outright fifth at eight under.

Reigning U.S. Open champion Bryson DeChambeau (71), four-time major winner Rory McIlroy (72) and former world number one Jordan Spieth (73) ended the event in a share of 18th position at one under.

Memorial Tournament runaway leader Jon Rahm has been forced to withdraw from the event after testing positive to COVID-19 on Saturday.

Rahm had carded back-to-back rounds of 64 and 65, including a hole-in-one on Sunday, to lead by six shots at 18-under from Collin Morikawa and Patrick Cantlay at 12-under.

However, the Spanish world number three, who was asymptomatic, was informed by officials immediately following his round in dramatic scenes that he had tested positive and would be required to pull out of the event.

Rahm was seen on the TV broadcast being informed of the news by an official, reacting by stooping in anguish and emotionally putting his hands to his face, before walking off the course shaking his head.

The PGA TOUR put out a statement clarifying that Rahm had been subject to contact-tracing protocols as he had come in close contact with a person who was COVID positive.

The statement said: "Rahm has tested negative every day, but his most recent test – which was performed after the conclusion of his second round (rain delayed) and before the start of his third round – returned positive at approximately 4:20 p.m. ET while Rahm was on the golf course.

"The PGA TOUR’s medical advisor requested a confirmatory test on the original sample, which came back at 6:05 p.m. ET, and was also positive.

"The PGA TOUR’s medical advisor notified Rahm immediately upon completion of his round, and under TOUR protocols, he will be withdrawn from the competition. Rahm is now in isolation, and in accordance with CDC guidelines, he will need to remain in isolation through Tuesday, June 15.

"While this is an incredibly unfortunate situation, throughout 50 events since the PGA TOUR’s Return to Golf, there have been only four positive tests (including Rahm) within competition; Rahm is the first positive, asymptomatic case as part of the TOUR’s routine, contact-tracing protocols."

Rahm had been the equal leader at eight-under on Friday after the second round was suspended due to darkness, alongside Cantlay.

The Spaniard raced away with 11 birdies on Saturday as well as a hole-in-one on the 16th to move into the outright lead as he completed his second round.

Morikawa and Cantlay suddenly find themselves in the lead, with the former having shot a six-under 66 on Saturday with eight birdies.

Cantlay finished with a four-under 68 to sit equal with Morikawa at 12-under, with four birdies in his round including sinking a 22-foot putt on the 18th.

South African Branden Grace and American Scottie Scheffler are both tied for second at nine-under, with Max Homa next best at six-under.

Defending champion Jon Rahm joined Patrick Cantlay at the top of the leaderboard before the second round of the Memorial Tournament was suspended due to darkness.

The opening round was hit by storms at Muirfield Village, where most of the field managed to complete their second rounds on Friday.

Rahm – eyeing back-to-back Memorial titles – was through 13 holes when play was called for the day, the Spanish star level at eight under alongside Cantlay.

Cantlay had posted a five-under-par 67 to surge to the top of the standings in Dublin, Ohio.

The 2019 champion, Cantlay played 33 holes on Friday to be tied for the two-stroke lead through 36 holes, ahead of fellow American Scottie Scheffler (71).

Carlos Ortiz (68), Max Homa (through 14), Xander Schauffele (through 12) and Rickie Fowler (through 11) ended the day three shots off the pace at the PGA Tour event.

Overnight leader Collin Morikawa completed 12 holes but slipped down to a tie for eighth at four under, alongside the likes of Masters champion Hideki Matsuyama.

Former world number one and three-time major champion Jordan Spieth recorded a five-under-par 67 to bounce back from his first-round 76 – the American improving to one under.

Reigning U.S. Open champion Bryson DeChambeau also completed his round – an even-par 72 – to be seven strokes behind Rahm and Cantlay but it was a testing day.

DeChambeau was taunted by fans amid his ongoing feud with fellow star Brooks Koepka, with approximately 10 spectators ejected.

There is no love lost between DeChambeau and Koepka, particularly after footage of the latter emerged during a post-round interview at the US PGA Championship.

In a leaked viral video, four-time major champion Koepka was seen rolling his eyes at DeChambeau and cursed in frustration during the interview.

After Friday's second round, DeChambeau said: "I think it's absolutely flattering what they're doing. They can keep calling me that all day if they want to, I've got no issue with it.

"When you look at it, to most people it's they think it's a distraction, but I grew up learning how to deal with that stuff and I honestly thought it was flattering.''

On Koepka – who is not playing this week – DeChambeau said: "Look, I've got nothing against him. I've got no issues at all. If he wants to play that game, that's great. I'm going to keep trying to play my best game and when it comes down to it, when somebody's that bothered by someone else it is flattering."

Meanwhile, four-time major champion Rory McIlroy shot back-to-back 72s to be even par.

Collin Morikawa carded a six-under-par 66 to claim a one-stroke lead before bad weather halted the opening round of the Memorial Tournament.

Thunderstorms forced a weather-hit day one to be suspended at Muirfield Village, where Morikawa managed to set the early pace before play was stopped on Thursday.

Morikawa – last year's US PGA Championship winner – was almost flawless in Dublin, Ohio after holing seven birdies and just one bogey.

A run of three consecutive birdies and four in five to start his back nine sent Morikawa to the top of the leaderboard, just ahead of fellow American Adam Long.

"It was definitely the rain," Morikawa said. "The greens were soft enough and they're receptive. But you have to hit the fairway. Out here, wet rough, it's not going to help when the rough is pretty long.

Bo Hoag, Nick Taylor, Xander Schauffele and Rafa Cabrera Bello also completed their rounds and ended the day two strokes off the pace, while defending champion Jon Rahm, Justin Thomas and Rickie Fowler are among a group a shot further back at three under.

Reigning U.S. Open champion and 2018 Memorial Tournament winner Bryson DeChambeau – gearing up for his upcoming title defence at Torrey Pines Golf Course in San Diego this month – was two under through three holes at the time of the suspension.

Former world number one Jordan Spieth also completed three holes – one under – when play was called off, while Masters champion Hideki Matsuyama, who won the PGA Tour event in 2014, did complete his round following a one-over-par 73.

Four-time major champion Rory McIlroy will return to finish his round early on Friday after going one over through two holes in wet conditions.

Keith Mitchell leads Rory McIlroy by two strokes following three rounds of the Wells Fargo Championship, where Bryson DeChambeau endured a whirlwind 24 hours.

American golfer Mitchell carded a five-under-par 66 to surge to the top of the leaderboard at Quail Hollow on Saturday.

Mitchell, whose solitary PGA Tour title came via the 2019 Honda Classic, was flawless in the penultimate round after holing five birdies without dropping a shot.

But four-time major champion McIlroy is lurking in Charlotte, where the two-time Wells Fargo Championship winner is two shots off the pace.

Former world number one McIlroy, who raced out to the lead, posted a three-under-par 68 to be tied for second position alongside Gary Woodland (70).

McIlroy was also two strokes back at the halfway stage of the tournament on Friday, having made the cut for the first time in two months.

A healthy crowd was in attendance to watch McIlroy lurk heading into the final round and the Northern Irish star – amid the coronavirus pandemic that has impacted attendances – said: "I sort of realised that it's hard for me to bring the best out in myself without that atmosphere that we had today. I'm excited to be in the position I'm in."

U.S. Open champion DeChambeau ended the day eight shots behind Mitchell following his third-round 68.

DeChambeau flew home to Dallas on Friday after thinking he missed the cut. When the cut changed, the American star boarded another flight back to Charlotte.

"It was funny," said DeChambeau. "We did a lot of scrambling last night to get back. One of the scenarios was like turning right back around, but the crew couldn't, you know, refuel and their hours were out. So we had to get a new crew, if anything, and it just didn't work out.

"So we're like, 'Well, let's just go in the morning'. So I left at 02:45am on a flight and I got here at 06:20am Drove 30 minutes to the golf course, put on my clothes in the locker room and headed out to the putting green. I did get a workout last night, though."

DeChambeau has a double-bogey or worse in each of his rounds at this year's Wells Fargo Championship. It is the fifth time in his career that he has recorded at least one double-bogey or worse in each of the first three rounds of a Tour event.

If there ever was a course to get slumping Rory McIlroy back on track, Quail Hollow might be it. 

McIlroy shot a five-under-par 66 Friday at the Wells Fargo Championship to make the cut for the first time in two months and reach four-under for the tournament, two strokes behind leaders Matt Wallace, Gary Woodland and Patrick Rodgers. 

First-round leader Phil Mickelson dropped to a tie for 10th overall after carding a 75 at the Charlotte, North Carolina course. 

Only Roger Sloan (64) went lower than McIlroy in the second round, as the 32-year-old recorded six birdies and just one bogey after shooting 72 in the first round. 

The Northern Irishman recorded his first PGA Tour victory at Quail Hollow in 2010 and won there again in 2015. He lost out to Rickie Fowler in a three-man playoff in 2012. 

McIlroy is playing his first tournament since missing the cut at the Masters and The Players Championship, the latter coming a week after a 10th-place finish at the Arnold Palmer invitational in early March. 

"When you played the way I played sort of through that stretch in March and into April, you're going to feel like you're not as close as you probably are," McIlroy told reporters. 

"But I worked hard after Augusta. I took a week off and reset, which I needed.

"Then I put my head down and worked hard and at least felt better about everything coming in here."

Among the three leaders heading into the weekend, Wallace shot 67 Friday, Rodgers 68 and Woodland 69.

Kramer Hickok is one stroke back at five-under for the tournament, while Scott Piercy, Keith Mitchell, Carlos Ortiz and Scott Stallings are tied with McIlroy at four-under. 

Mickelson and two-time Masters champion Bubba Watson are among those at three-under, while 2018 Masters winner Patrick Reed sits four back of the leaders. 

Justin Thomas is six back entering the weekend, while 2020 U.S. Open champion Bryson DeChambeau and 2020 Open Championship winner Shane Lowry just made the two-over cut. 

Among those who missed the cut were past major champions Fowler, Jason Day, Francesco Molinari and Lucas Glover  in addition to defending champion Max Homa and Jon Rahm.

Rahm had made 22 consecutive cuts, the longest active streak on Tour.

Phil Mickelson knows Quail Hollow as well as any course on the PGA Tour, and his comfort there was clear on Thursday as he earned a two-stroke lead in the opening round of the Wells Fargo Championship. 

Mickelson carded a seven-under-par 64 to set the early pace in Charlotte, North Carolina, where the five-time major champion is looking for his first win in 17 consecutive appearances at the event. 

The 50-year-old has always played well there, though, finishing in the top five in half of his 16 previous starts at the tournament. 

Lee Kyoung-hoon and Keegan Bradley were two shots back after shooting 66s.

Mickelson recorded just one bogey on day one while carding eight birdies, including four of the last five holes. 

He won two Champions Tour events last year in his debut season on that circuit, but has not captured a PGA Tour title since winning at Pebble Beach in February 2019. 

Mickelson's last opening-round lead or co-lead came three weeks prior to that in Palm Springs, but he did not want to put any additional pressure on himself after Thursday's strong start.

"I don't want to jump ahead, I want to play a good round tomorrow," said Mickelson, who recorded his lowest score on Tour since a 63 in the second round of the 2020 Travelers Championship. "I have an opportunity to play a course I love with a great pairing.

"I'm playing well and I just want to kind of not get ahead of myself and go play another fun round."

Mickelson, who entered the week ranked number 115 in the world, has 30 career opening-round leads/co-lads – the second most on Tour since 1992.

American star Justin Thomas closed out the first round five shots off the pace, while U.S. Open champion Bryson DeChambeau and 2012 tournament winner Rickie Fowler are a stroke further back.

Former Masters champion Patrick Reed shot a 71 as Xander Schauffele and former world number one Rory McIlroy ended the day one over the card.

McIlroy – winner of the Wells Fargo Championship in 2015 – mixed three bogeys and two birdies on a challenging day for the four-time major champion.

Jon Rahm struggled following his opening-round 76, while defending champion Max Homa's bid for back-to-back titles started with a six-over-par 77.

Marc Leishman and Cameron Smith claimed the Zurich Classic of New Orleans after defeating Louis Oosthuizen and Charl Schwartzel in a play-off.

Leishman and Smith, who carded a final-round 70, won the first play-off hole to trump Oosthuizen and Schwartzel in the race for the title on Sunday.

Australian pair Leishman and Smith and South Africa's Oosthuizen-Schwartzel pairing (71) finished level at 20 under par through 72 holes, a shot clear of Americans Richy Werenski and Peter Uihlein (67).

The final round was the second foursome format of the tournament, after Thursday and Saturday's rounds used alternate-shot play at TPC Louisiana.

Smith and Leishman soared to the top of the leaderboard thanks to 12 holes of flawless golf, which featured four birdies, before three bogeys in five holes allowed Oosthuizen-Schwartzel to join them at the summit.

Leishman's birdie chip at the 16th hole tied the South Africans as the two teams headed for a play-off – the first play-off in the team format of the event since former Masters runner-up Smith and Jonas Blixt prevailed in 2017.

Defending champions Jon Rahm and Ryan Palmer (70) finished 17 under overall, Xander Schauffele-Patrick Cantlay (67) and Henrik Stenson-Justin Rose (70) were two shots further back, while Tony Finau and Cameron Champ crashed down the leaderboard from joint-second to 17th place following their 76.

Schauffele and Cantlay combined for eight birdies and claimed a share of 11th place – tying the record for most par-breakers in a foursomes round at the tournament since it became a team event.

Louis Oosthuizen and Charl Schwartzel turned in a nine-under 63 in four-ball play to take the lead after the third round of the Zurich Classic of New Orleans. 

The South African duo are 19-under for the tournament and were one of six teams to record a 63, vaulting them past second-round leaders Tony Finau and Cameron Champ by a stroke. 

Australians Marc Leishman and Cameron Smith also shot nine-under and are tied for second with the American pair. 

The top of the leaderboard at TPC Louisiana is crowded, with Bubba Watson and Scottie Scheffler sitting two shots back along with first-round leaders Viktor Hovland and Kris Ventura. 

The tournament, which switched to a team event in 2017, features four-ball in the first and third rounds and foursomes in the second and fourth. 

Three teams are at 16 under and nine more at 15 under, with the latter group including defending champions Jon Rahm and Ryan Palmer. 

The shot of the day belonged to Sam Ryder, who holed a five iron from 206 yards at No. 2 for a double eagle -- the first at the tournament since Rob Oppenheim did it in 2018.

Tony Finau and Cameron Champ posted a four-under-par 68 in alternate-shot play for a share of the Zurich Classic of New Orleans lead following the second round.

After the opening round consisted of four-ball play at the longstanding PGA Tour tournament, which turned into a team event in 2017, day two switched to the foursomes format.

American pair Finau and Champ head into the weekend 13 under through 36 holes, two strokes clear alongside Norwegian duo Viktor Hovland and Kris Ventura, who were tied for the lead after day one.

Hovland and Ventura posted a 69 on Friday to stay atop the leaderboard at TPC Louisiana.

"I know we're having a good time with this format up to this point," Finau said. "We've both played some really solid golf, and we find ourselves at the top of the leaderboard.

"We'll do what we've been doing the last couple days, which is enjoy each other's company and not add any bonus pressure when it comes to team-mate golf."

Justin Rose-Henrik Stenson and Bubba Watson-Scottie Scheffler are 11 under at the halfway stage of the tournament.

Defending champions Jon Rahm and Ryan Palmer recorded a two-under-par 71 to be five shots behind.

Meanwhile, Graeme McDowell – playing alongside Matt Wallace – aced the 217-yard 17th hole to finish the day with a 70.

Viktor Hovland and Kris Ventura ended the opening round tied for the lead alongside Brice Garnett and Scott Stallings at the Zurich Classic of New Orleans.

The longstanding PGA Tour tournament turned into a team event in 2017, with the first and third rounds consisting of four-ball where everyone plays their own shot and the best score counts. The second and fourth rounds feature foursome play or alternate shot.

On Thursday, after the 2020 edition was cancelled due to the coronavirus pandemic, Hovland-Ventura and Garnett-Stallings moved a stroke clear atop the leaderboard at TPC Louisiana.

Both teams carded bogey-free 10-under-par 62s, ahead of Cameron Champ-Tony Finau, Billy Horschel-Sam Burns, Keegan Bradley-Brendan Steele, Lee Kyoung-hoon-Kyle Stanley, Mark Hubbard-Sebastian Cappelen, Louis Oosthuizen-Charl Schwartzel and March Leishman-Cameron Smith.

Xander Schauffele, who threatened to break through for his maiden major title at the Masters, and Patrick Cantlay are eight under heading into the second round, along with Bubba Watson-Scottie Scheffler.

Defending champions Jon Rahm and Ryan Palmer opened their bid for back-to-back titles with a 65 to earn a share of 16th position, three strokes off the pace, while Justin Rose-Henrik Stenson are also seven under.

Hideki Matsuyama made history as he became the first Japanese man to win a major tournament after claiming The Masters by one shot in a thrilling finale at Augusta.

Matsuyama was on the cusp of history heading into Sunday's final round, the 29-year-old carrying a four-stroke lead as he looked to replicate the major success of countrywomen Hinako Shibuno (2019 Women's British Open) and Chako Higuchi (1977 LPGA Championship) on the men's circuit.

A five-time PGA Tour winner before this success, Matsuyama withstood a wobble and the threat posed by Xander Schauffele (72) to complete a history-making performance in Georgia, where he triumphed at 10 under par overall following a 73 to get his hands on the green jacket.

Will Zalatoris (70) earned outright second position, two strokes ahead of former world number one and 2015 Masters winner Jordan Spieth (70) and 2019 runner-up Schauffele.

Matsuyama – four strokes clear at the start of the day – had extended his lead to five at the turn, but his title bid threatened to turn sour as Schauffele closed in and Zalatoris loomed.

After finding water at the par-five 15th hole, Matsuyama took the penalty and cleaned up for bogey as Schauffele continued to heap pressure on the Japanese hopeful, cutting the lead to two shots with his fourth consecutive birdie.

But Schauffele's pursuit of a maiden major collapsed when the American – seven back at the 12th tee before rallying – also found water before sending his next shot into the crowd.

Matsuyama had a routine par to move three shots clear with two to play, but he dropped another shot, his lead down to two ahead of Zalatoris as an ill-timed triple-bogey sent 2019 runner-up Schauffele down to equal third alongside Spieth – four shots behind.

It was Schauffele's first triple-bogey in a major championship – a run of 1,042 holes.

That was the breathing space Matsuyama needed as Japan's new poster boy held his nerve, doing what he needed to do during the final two holes in front of an appreciative crowd on the 18th, where not even a bogey could wipe away the champion's smile.

Matsuyama (2011) became the third Masters champion in the last five years to have previously earned low amateur honours, following in the footsteps of Tiger Woods (2019, low amateur in 1995) and Sergio Garcia (2017, low amateur in 1999).

Elsewhere, Jon Rahm (66) and Marc Leishman (73) shared fifth position at six under, while one-time major champion Justin Rose had to settle for seventh – five shots off the pace – following his final-round 74 as 2018 Masters champion Patrick Reed (69) surged into a tie for eighth.

A sleep-deprived Jon Rahm is confident he can mount a strong challenge for a first major title following the "major life experience" of becoming a father last weekend.

The world number three will tee off at Augusta on Thursday just five days after his wife, Kelley, gave birth to baby Kepa.

Doting new dad Rahm has been relieved of diaper-changing duties to make the trip to Georgia for the first major of the year.

Rahm is among the favourites to don the green jacket on Sunday and, despite only arriving on the eve of the tournament, the Spaniard fancies his chances of celebrating his new arrival by experiencing his finest hour on a golf course.

"My concern is that I'm coming to a Masters, and from Thursday to Monday didn't sleep much, didn't hit a single golf shot," he said.

"You know, maybe I haven't prepared as much as I have in the past, but definitely I'm mentally in a different state.

"A lot of times practicing for a major you spend so much time thinking about golf, and for four or five days, it wasn't even on my mind, which is kind of refreshing.

"Coming here later than usual, but I'm here ready to compete. I wouldn't be here otherwise."

He added: "I'm not concerned. I went through a major life experience. If anything I'm just happier. I'm thankful to be here. If anything, definitely a different mental state, but I would say it's a better mental state."

Rahm revealed he had not been to Augusta since he finished in a tie for seventh in the Masters last November, but says that will not be an issue.

He said: "The course hasn't changed. I might need to spend a little bit of extra time today hitting lag putts and hitting some chips because the last time we played here it was a little softer and slower, but tee to green it doesn't really change much.

"Luckily I've played here before, and I always have a good vibe when I come here."

Rahm, Rory McIlroy and Xander Schauffele will tee off for their first round at 10:42 local time.
