Corey Conners won the Valero Texas Open for the second time on Sunday, carding a bogey-free four-under 68 for a one-stroke victory ahead of rookie Sam Stevens.

The Canadian world number 40, who won at TPC San Antonio in 2019, had headed into the final day in second place behind Patrick Rodgers, who had five bogeys on Sunday to slip out of contention.

Conners was faultless, with birdies on the par-five second, followed by the sixth, ninth and 15th holes, opening up a three-shot lead upon the latter.

But Stevens stormed into contention with an eagle on the par-four 17th with a brilliant approach off the tee from 299 yards, before missing a nine-foot birdie putt on the 18th that may have forced a playoff.

Conners held his nerve with a three-foot putt for par on the last to secure victory, his second on the PGA Tour, both in San Antonio. The Canadian's next-best PGA result was a third-place finish at last year's Arnold Palmer Invitational.

The final day surge of 26-year-old Stevens came off a six-under 66 that included five birdies and two eagles to finish at 14-under overall.

Stevens' runner-up finish comes a week after coming third at the Corales Puntacana Championship.

Sam Ryder (66 on Sunday) and Matt Kuchar (68) were tied for third at 13 under, with Rodgers ending up with a one-over final day 73 to fall back to 11 under.

Chez Reavie carded a seven-under 65 to finish tied for sixth at 10-under overall, while Rickie Fowler had a final day six-under 66 to end up eight under.

Patrick Rodgers struggled to match his first two rounds at the Valero Texas Open but nevertheless held his nerve to take a one-stoke lead at 12 under into the final day.

The 30-year-old had led overnight after play was halted early on Friday, following an impressive five-under 67 to back up an opening round of six-under 66.

But after carding a more sedate one-under 71 at TPC San Antonio, the American was left with just a single-stroke lead ahead of Canada's Corey Conners, who held on to second place with a three-under 69.

Veteran Matt Kuchar had looked set to challenge for top spot before a double bogey on the 18th derailed his pursuit, though he still finished in a respectable third, three shots off at nine-under for the tournament.

American duo Sam Stevens and Chris Kirk are tied for fourth at eight under, while South Korea's An Byeong-hun and Ireland's Padraig Harrington are among those in a six-way tie for sixth.

Rodgers is chasing a first win on the PGA Tour, having arrived in Texas with six missed cuts from his past eight starts, though he did secure a top-15 finish at the Phoenix Open.

At the conclusion of Friday's play at the Valero Texas Open it was Patrick Rodgers leading the field by three strokes, although many are yet to complete their second round.

Rodgers, 30, has never won on the PGA Tour, and has had an up-and-down season up until this point. While he has two top-10s, and a top-15 at the Phoenix Open, he also came into this event with six missed cuts from his past eight starts.

His six-under 66 was one of the best scores from the opening round, and he followed it with a five-under 67 after birdieing five of his last six holes to race out to a healthy lead.

In a tie for second is Canada's Corey Conners, who would be disappointed to shoot even par after his eight-under start. Joining him at eight under is Mexico's Roberto Diaz, who will have his sights set even higher as he was only through 10 holes in his second round before darkness halted play.

American duo Michael Thompson and Brendon Todd (through 15) are at seven under in a tie for fourth, while Belgium's Thomas Detry is joined by veteran Matt Kuchar and rising talent Eric Cole at six under.

Recent winner of The Honda Classic, Chris Kirk, is part of the logjam at five under rounding out the top 10, and Rickie Fowler has finished right on the projected cut-line at one under.

Justin Lower leads the Valero Texas Open through nine holes with play suspended due to darkness as Padraig Harrington and Matt Kuchar joined the group one stroke behind on Thursday.

The opening round was called off early in fading light, with play having been delayed numerous times in the morning due to fog in South Texas.

Lower, 33, got through the first half of his round, managing an eagle on the par-five 14th hole along with three birdies for a five under start.

Three-time major winner Padraig Harrington, 51, wound back the clock in his 333rd start in his 28th season. The Irishman, playing in familiar conditions, carded a four-under 68 with six birdies.

Fellow veteran Matt Kuchar had a similar round with six birdies and two bogeys for a four-under 68 to be tied for second.

The 44-year-old American and Harrington are alongside South Africa's M.J. Daffue, Mexico's Roberto Diaz and USA's Patrick Rodgers.

Fresh from winning last week's Corales Puntacana Championship, Matt Wallace is in a group of eight players, including Canada's Corey Conners (through nine holes), one stroke behind at three under overall.

Pre-tournament favourite Tyrrell Hatton only got through 10 holes to be two under, while Rickie Fowler and defending champion J.J Spaun were both even after 11 holes.

JJ Spaun landed the Valero Texas Open title after coming back from a double-bogey on the first hole to shoot 69 in the final round, clinching a place at the Masters in the process.

Spaun finished two strokes clear of the field on 13 under par, with Australian Matt Jones and American Matt Kuchar sharing second place at 11 under.

With his win, the Californian became the first player since Tiger Woods in 2008 to win a PGA Tour event after double-bogeying the opening hole of the final round.

The 31-year-old went bogey-free the rest of the way, collecting birdies on the sixth, eighth, ninth, 11th and 14th holes – giving him a birdie on the par-five 14th hole in all four rounds.

It is the first PGA Tour win of Spaun's career, and with it, he punched his ticket to Augusta National in just a few days.

Spaun said the scale of his achievement was hard to believe.

"I think a year ago to even be on tour I would have been telling you I'd have to do a lot of work to get there," he said.

"But to be here, and to overcome a lot of things and finally get a win, that's everything you dream of. It's incredible. I'm speechless."

On his early double-bogey and how he recovered, he said the moment actually calmed him down.

"It didn't bother me as much as you would think – if anything, it kind of calmed me down," he said.

"I knew there was still a lot of golf, and I would rather double the first hole than the last hole, so I just knew if I stayed patient and kept plugging away and put myself in contention with nine holes to play, that's all I could ask for."

The best performances from the fourth round were a pair of 66s posted by Jones, who finished second, and Keegan Bradley, who jumped up into a tie for eighth.

Among those one stroke worse on the day with 67s were Canadian Adam Hadwin, who finished in a tie for fourth, and Jordan Spieth, who was at even par coming into the round and flew up the leaderboard into a tie for 35th at five under.

Of the three joint-leaders with Spaun coming into Sunday's play, Beau Hossler finished the highest, tied for fourth at 10 under after shooting even par; South African Dylan Frittelli dropped one stroke and tied for eighth; and Brandt Snedeker ended with a whimper, finishing three over for the round to fall to a tie for 18th.

After a scorching start to the week saw Russell Knox as the outright leader with a first-round 65, he followed it with rounds of 76, 71 and 76 again to finish the weekend where the cut-line was at even par.

Brandt Snedeker and Beau Hossler both shot five-under-par 67 to join JJ Spaun and Dylan Frittelli atop the leaderboard, after the third round of the Valero Texas Open on Saturday.

Spaun and Frittelli bogeyed the last par-five 18th hole to finish on 10-under-par after 54 holes, shooting rounds of 69 and 70 respectively on Saturday.

It would have been a five-way tie for the lead had Scott Stallings not also bogeyed the final hole, finding the rough and then the far-side bunker on his second and third shots.

Among the many in the field who have yet to qualify for the US Masters, Matt Kuchar is two strokes back from the leaders on eight-under-par after three rounds.

In what is essentially the final qualifier for the first major of the year, and having missed the cut at Augusta last year, Kuchar is aware of the stakes.

"I think quality play trumps anything," he said.

"I'd take execution over course knowledge any day of the week. I think it's going to take just quality golf tomorrow to win this thing."

After shooting a bogey-free round on Friday, second round leader Ryan Palmer tumbled down the leaderboard on Saturday with a five-over-par 77, finishing in 21st on five-under-par.

Spaun and Hossler are both looking for their first PGA Tour win, while Frittelli last won in 2019 at the John Deere Classic and Snedeker took the Wyndham Championship in 2018.

Hossler finished with momentum on Saturday, making three consecutive birdies from the 14th hole. His career-best finish was a second at the Houston Open in 2018.

A win for Snedeker would make for his 13th trip to Augusta.

Rory McIlroy and Bryson DeChambeau were among the big names whose preparation for the 2022 Masters took a blow at the Valero Texas Open on Friday.

In the last week before the first major of the year, McIlroy, DeChambeau, Jason Day and Rickie Fowler all missed the cut.

With the cut line at one under par, McIlroy's second-round 73 left him one over, while DeChambeau was way off the pace at five over following his 76.

DeChambeau has not long returned from injury, finishing bottom of his group at last week's WGC-Dell Technologies Match Play, losing two of his three matches and tying the other.

When he started with a triple-bogey on Friday, it became clear the 2020 U.S. Open champion would not be continuing into the weekend in Texas.

Meanwhile, McIlroy had been in encouraging form a month ago, but his performances have gradually declined to the point an Augusta challenge again seems unlikely.

The Masters remains the only major McIlroy is yet to win.

While the big names faltered, world number 547 Kevin Chappell excelled, finishing his second round in a tie for second place, two shots behind leader Ryan Palmer.

Once a contender on the PGA Tour, Chappell's only win came at this event five years ago.

"I just feel at ease around this place," he said after shooting a 65. "My soul and this golf course get along. I really enjoy being here.

"I'm excited about where my game is because I don't think I've played great yet.

"It's not like the ball is coming out of the middle of the clubface every time and flying where I'm looking, but I've been able to scramble and get the ball in the hole."

Ryan Palmer holds a two-stroke lead over the field after the second round of the Valero Texas Open.

Palmer, who shot four under in round one, finished with a six-under 66 to move to 10 under.

The American finished the round bogey-free, and three times carded back-to-back birdies on the second and third, eighth and ninth, and 14th and 15th.

Speaking to the media after his round, Palmer said the key to his success is to limit the severity of his mistakes.

"It's a golf course – if you get it off-line, you're going to struggle," he said. 

"I was able to keep the ball in front of me. When I've missed fairways, I've gotten fortunate breaks, I think. 

"[This] weekend, it's a matter of just avoiding those big misses."

Kevin Chappell worked his way into a three-way tie for second after he shot 65 for the best round of the day, and he is joined at eight under by South Africa's Dylan Frittelli and American Matt Kuchar.

Chappell – who is ranked as the world number 547 – played the course beautifully, nabbing an eagle on the par five second hole before going bogey-free and birdieing the eighth, ninth, 12th, 15th and 17th.

The leader after round one, Russell Knox, had a poor day, bogeying four of his first six holes on the way to shooting 76, dropping down to three under and a tie for 27th.

With the cut-line at even par, Jordan Spieth followed up his even par first round with a 70 on Friday to sneak into the frame.

Plenty of notable names who will hope to contest the US Masters crown next week failed to make the cut, including Jason Day, Rory McIlroy, Rickie Fowler and Bryson DeChambeau.

Hideki Matsuyama's defence of his Masters title has been left in doubt after a neck injury forced the 30-year-old to withdraw from the Valero Texas Open.

Matsuyama became the first male Japanese golfer to win a major championship with last year's success at Augusta National, edging out American trio Will Zalatoris, Xander Schauffele, and Jordan Spieth in the final round for a one-stroke victory.

However, with less than a week remaining until the 2022 edition of the Masters begins on April 7, Matsuyama withdrew nine holes into his second round in San Antonio, citing a neck injury. 

Reports have suggested that the 30-year-old has suffered a recurrence of the same injury which kept him out of The Players Championship last month, eventually won by Australia's Cameron Smith.

Matsuyama's most recent result saw him tie for 20th position at the Arnold Palmer Invitational, and he has won two PGA titles since last year's Augusta triumph, winning the Zozo Championship on home soil last October before lifting Hawaii's Sony Open in a play-off in January.

Matsuyama sits 12th in the world rankings, and has made the top 10 in four of the 10 PGA events at which he has featured in the 2022 season.

Russell Knox's bogey-free 65 earned him top spot on the Valero Texas Open leaderboard after the first round of action at TPC San Antonio.

The Scotsman was excellent all day, highlighted by his four consecutive birdies starting on the 12th hole to finish seven under.

He is one stroke ahead of Denmark's Rasmus Hojgaard, who eagled the par-five 18th to finish at six under and make up for his double-bogey on nine.

Speaking to the media after his round, Knox spoke about getting control of his driver, and the potential to play in next week's US Masters.

"I would love to win and get to play next week," he said. 

"I know my game is good, so I've got to keep playing well and see if I can have a great finish.

"I've been a little more consistent tee to green. I'm back to kind of feeling like the way I should be playing, which has been nice.

"Off the tee's been kind of important for me. Over the last couple years I just kind of got off track slightly, hitting a few wayward tee shots.

"I've worked hard with my coach, Mark McCann, and we've really gone back to fundamentals, got my set-up correct and it just gives me the freedom to kind of swing away.

"I know it's never going to be perfect, but the last couple months it's really been a strength of mine again."

Matt Kuchar and Englishman Aaron Rai are in a four-player tie for third at five under, with India's Anirban Lahiri and Australian Matthew Jones part of the large contingent at four under.

In-form Canadian Corey Conners finished tied with Richard Bland and Tony Finau with a big group at two under, with Ian Poulter and Keegan Bradley one shot further back.

It was an up-and-down round for Rickie Fowler, with his bogey on 18 forcing him to accept even-par for the day, which he shared with stars Rory McIlroy and Jordan Spieth.

Bryson DeChambeau and Lee Westwood highlighted the group at plus one, while Jason Day and Hideki Matsuyama will be fighting to make the cut after carding plus two.

Jordan Spieth returned to the winners' circle and just in time for the upcoming Masters after celebrating a drought-ending Texas Open victory.

Not since winning the 2017 Open Championship had former world number one Spieth claimed a title on the PGA Tour.

But American star Spieth – tied for the lead at the end of the third round – ended his agonising wait at TPC San Antonio on Sunday following 1,351 days.

Spieth snapped a slump that lasted almost four years, posting a six-under-par 66 and seven birdies for a two-stroke victory ahead of Charley Hoffman (66) at 18 under overall.

Three-time major champion Spieth will now return to Augusta – the scene of his 2015 triumph – on April 8 with renewed confidence after emerging from the wilderness.

Spieth – who threatened to break through this year, having either been leader or co-leader at the Phoenix Open and Pebble Beach Pro-Am before finishing tied for fourth and third respectively – earned his 12th PGA Tour title.

The 27-year-old and 2015 Texas Open runner-up became the 92nd player in Tour history to reach 12 wins and moved into a tie for 82nd on the all-time list.

Five players in the last 40 years have earned 12 titles before turning 28 – Phil Mickelson (27 years and 209 days), Tiger Woods (23 years and 243 days), Rory McIlroy (27 years and 124 days), Justin Thomas (26 years and 251 days) and now Spieth (27 years and 251 days).

Hoffman – the 2016 champion – threatened to derail Spieth's bid to end his long wait, having moved within a shot of the lead before the latter birdied the 17th hole.

Spieth made Hoffman settle for back-to-back runners-up cheques after he finished second in 2019 prior to the 2020 event being cancelled due to the coronavirus pandemic.

Matt Wallace (70) finished outright third and four shots adrift of Spieth, two strokes better off than Lucas Glover (66).
