Scottie Scheffler reclaimed the world number one ranking after successfully defending his Waste Management Phoenix Open title with a two-stroke victory on Sunday.

Scheffler – after posting rounds of 68, 64 and 68 – closed in style with a six-under 65 to finish at 19-under overall.

He went bogey-free in his final round with four birdies and an eagle, showing his affinity for the TPC Scottsdale course after winning his first PGA Tour event at this tournament last season.

Scheffler's lead was down to only one stroke heading into the famous 16th hole, and while he could only muster a par, that proved to be enough as second-placed Nick Taylor made bogey, and Scheffler extended the lead to three strokes for a comfortable finish with a birdie on 17.

Speaking to CBS after stepping off the final green, Scheffler said he was proud of the way he battled through some average shots.

"I'm just proud of how I fought today," he said. "I didn't have my best stuff, so I grinded it out today. I wasn't hitting it good off the tee, my irons didn't feel sharp, but I played a great round of golf today."

Taylor birdied the 18th to finish alone in second at 17 under for his best result since winning the 2020 AT&T Pebble Beach Pro-Am.

The red-hot Jon Rahm ended up in sole possession of third at 14 under, fellow major champion Justin Thomas finished fourth at 13 under, and former world number one Jason Day continued his return to relevance with a fifth-place result at 12 under.

The highlight of the day came from Rickie Fowler, punctuating his T10 finish with an ace on the par-three seventh hole.

Jon Rahm and Adam Hadwin provided the highlight of the third round at the Phoenix Open, where Scottie Scheffler kept hold of the lead.

World number one Scheffler carded a 68 on Saturday to maintain the two-stroke lead he held after the opening two days.

A bogey on the 13th threatened to set Scheffler back, but he recovered with a birdie on the next hole and then another on the 17th.

Yet the highlight came from Rahm and Hadwin on the Stadium Course's famous 16th hole.

With the vociferous crowd having been deprived of much excitement up until then, Hadwin – who endured a frustrating round, dropping three bogeys – planting his tee shot close to the pin, setting up a simple putt for birdie.

If that shot had the spectators on their feet, then Rahm's exceptional putt had them positively in delirium soon after, as the world number three sunk an excellent effort to on his way to a three-under 68.

Rahm moved up to T2 alongside Nick Taylor, who found timely birdies on the last two holes to head back into the clubhouse on 11 under after three rounds.

Jordan Spieth, who went round in 63 on day two, carded 69 but dropped a place to T4 along with Hadwin, with Im Sung-jae, Tyrrell Hatton, Rickie Fowler and Jason Day moving up to joint-sixth. Xander Schauffele had a disappointing round, though, and dropped three places.

It was a similar story for world number one Rory McIlroy, who bogeyed on the fourth, seventh and 17th, as well as double-bogeying the 14th. His round of 70 leaves him on three under for the week, 10 behind Scheffler.

Sam Burns was the big mover of the day as he leapt up 28 places thanks to a stunning 64, matching Scheffler's effort from Friday.

Burns struck five birdies and eagled the 13th, and is part of a five-strong group tied for 11th at eight under.

Scottie Scheffler won his first PGA Tour title 12 months ago at the Waste Management Phoenix Open, and he is looking to defend that crown as he heads into the weekend with a two stroke lead at 10 under.

A large chunk of the field still have between five and eight holes remaining before they complete their second round, with a delay on Thursday creating a backlog as players had to finish their first round early Friday morning.

Scheffler was part of the early group and followed his opening 68 with a seven-under 64, and he was the only player to shoot seven under on his second trip around TPC Scottsdale.

It is shaping up as a tantalising battle at the top of the leaderboard after Jon Rahm's 66 clawed his way into a tie for second at eight under, where he is joined by round-one leader Adam Hadwin, who still has eight holes to play.

Im Sung-jae will have his sights set on posting the best second-round score, with time being called while he was six under through 12 holes, and tied for fourth with Wyndham Clark at seven under overall.

The only other player with a second-round score of six under or better was Venezuela's Jhonattan Vegas, rebounding strongly from an even-par opener, and he has four holes remaining to try and match Scheffler's heroics. 

Also in a tie for sixth with Vegas are former world number one Jason Day and current world number six Xander Schauffele, while the dangerous duo of Tom Kim and Jordan Spieth are one further back at five under.

Major champions Justin Thomas and Rory McIlroy are still in the hunt at three under, Viktor Hovland is at two under, and Hideki Matsuyama is at one under with five holes to play.

Half the field still need to complete their opening round, but Nick Taylor and Adam Hadwin raced around with the early group to take a share of the lead into Friday at the Waste Management Phoenix Open.

Taylor had a rollercoaster of a round, posting a one-over front-nine after an eagle, a double-bogey and a bogey, before flying home with six birdies on the back-nine to finish at five under.

He is joined by Canadian compatriot Hadwin as the only players to finish rounds of 66, but there is a strong chasing pack who were unable to finish that will look to snatch the round-one lead on Friday morning.

World number six Xander Schauffele is one stroke off the lead at four under, although he has finished his round, while joining him in a tie for third are former world number one Jason Day (through 10) and American Jim Herman (through 13).

The red-hot Jon Rahm will have his sights on the top, sitting at three under with five holes to play, as will both Max Homa and Keegan Bradley who are also at three under with six holes to play.

Major champion Matt Fitzpatrick is joined by Tony Finau, Sam Burns and Im Sung-jae in the group who completed one-under rounds, while Jordan Spieth posted an even-par 71.

Justin Thomas (one over through 12) will have a chance to still finish his first round under par, while Collin Morikawa, Patrick Cantlay and Cameron Young will all be trying to fight their way back into contention after finishing two over.

Scottie Scheffler edged Patrick Cantlay in a three-hole playoff to clinch the Phoenix Open title marking a dramatic turnaround after narrowly avoiding the cut on Friday.

World number 15 Scheffler and reigning PGA Tour Player of the Year Cantlay faced off after both finished 16-under-par following final day rounds of four-under-67.

Scheffler, who avoided the cut by one stroke, claimed the title with a birdie on the third hole of the playoff as Cantlay could only make par.

The 25-year-old American, who resides in Dallas, landed his second shot from the bunker on the green, before sinking a 26-yard putt for the decisive birdie, with Cantlay unable to match that.

The victory marks 2021 US Ryder Cup team member Scheffler's first PGA Tour title, having finished in the top 10 of three majors last year.

Scheffler had birdies on the 15th and the 17th holes to force his way into a playoff, although he almost won it outright on the 18th but missed a birdie putt from five feet.

Overnight leader Sahith Theegala found the water off the tee on the penultimate hole leading to a bogey that saw him slip from the lead.

Four-time major winner Brooks Koepka stormed into contention late, with three birdies and a bogey on his final four holes but fell short of the playoff.

Koepka and Theegala finished tied for third with Tokyo Olympics gold medalist Xander Schauffele at 15 under.

Scheffler had surged up the leaderboard on the third day with a nine-under-62 and backed that up with another strong round on Sunday.

Sam Ryder admitted he is still coming down off the adrenaline after his exhilarating hole in one on the 16th hole at the Phoenix Open on Saturday.

Ryder, who had endured a difficult round which included four bogeys and a double bogey, landed the ace, ushering in wild scenes of celebration from the packed onlooking crowd.

Play had to be halted for 15 minutes as debris was cleared off the course after the crowd splashed drinks and threw beer cans in the air in a raucous celebration of a rare feat.

The 32-year-old American became the first player to hit a hole in one on the 16th at Scottsdale since Francesco Molinari in 2015. Ryder is also the 10th player to achieve the feat.

“Still kind of coming down off the adrenaline,” Ryder told reporters, “But, yeah, it was pretty crazy.

"It's got to be number one. Nothing compares to that... it was a blur. I can't describe it."

Ryder hit a 124-yard tee shot which spun left and into the cup for the ace, re-living it afterwards.

"[Chris Kirk] hit a really good shot in the middle of the green, so I kind of got a little bit of feel off of what it was playing," Ryder explained. "It was just one of those things I was talking to my caddie, and it just ended up being a perfect 54 degree wedge.

"The club - everything always plays a little shorter in there, adrenaline or whatever it is, it's just, it always plays shorter. I just told him, 'it's just got to be that, doesn't it?' And he's like, 'that's all I ever thought'.

"We just talked through it a little bit and I was looking just out to the right and wanted to come down around his ball and maybe it was an accidental one-yard pull or something. It didn't look like it was moving too fast on the camera when I saw it, but in the air it just looked perfect."

Despite the hole in one, Ryder is eight strokes off the pace, sitting at six-under-overall ahead of the final day on Sunday.

Sahith Theegala recovered from a tricky start on Friday to maintain a breakout run at the Phoenix Open, where he now leads by two after two rounds.

Theegala, playing on a sponsor's exemption, had taken a one-shot lead into the day's play – albeit only after a suspension on Thursday due to bad light.

Starting with a par putt at the 17th on seven under, Theegala missed the hole and then bogeyed the 18th, too, falling back to five under.

But the 24-year-old, who turned professional in 2020 but is still living with his parents, got back in the groove in round two.

Three consecutive birdies and a fourth at the par-four fifth put Theegala in a great position, turning in 32 after a bogey at the eighth.

It only got better from there with a bogey-free back nine that featured four birdies, including at each of the last two holes – ending his Friday in far more convincing fashion than he had started it.

Theegala's only top-10 finish on the PGA Tour to date was a tie for eighth at the Sanderson Farms Championship in October, but he heads into the weekend at Scottsdale leading a star-studded field.

"I haven't had time to let it set in," he said after signing for a seven-under 64 to move to 12 under.

"Hopefully I don't think too much about it, because obviously what I've been doing has been working the first couple days.

"I'm just thankful that I'm here and trying to make the most of the opportunity – no expectations at all, honestly."

Having already threatened to crumble once, the pressure is only set to ramp up from here. Theegala's closest challengers are Brooks Koepka (66) and Xander Schauffele (65) at 10 under. Patrick Cantlay (66) is a shot further back.

"I'm ready to embrace whatever is ahead of me this weekend," Theegala added.

Brooks Koepka made a strong start to the Phoenix Open as he heads into day two in a tie for third at five under par, with the four-time major winner looking to put an "embarrassing" fall from grace behind him.

Koepka has not won a tournament since succeeding in Phoenix a little under a year ago – while he impressed at the PGA Championship in May, finishing joint-second, Koepka is not happy with how the past 12 months or so have gone.

He teed off in Arizona ranked 20th in the world, something of a far cry from spending 47 weeks at number one across 2018 and 2019 – three of his four major wins came in those years.

Koepka, rarely one to mince his words, feels ashamed of his slide, even if he puts it partly down to injury.

"That's embarrassing to be 20th, I feel like," he said after his first round on Thursday.

"A lot of it has to do with injury, man. I've been hurt, on the sidelines. Not playing, playing through injury, you can't compete with guys out here.

"It's nice to be somewhat healthy and get out here, and I mean, I'm not too worried about it [the ranking], it will bounce back up."

Indeed, there was nothing embarrassing about his performance at TPC Scottsdale on day one, his six birdies – offset by a single bogey – putting him right near the top of the leaderboard.

Nevertheless, he still has a plenty of work to do.

Lee Kyoung-hoon is one shot better off thanks to a glorious showing after the turn, playing the front nine five under par after starting on the ninth hole.

But leading the way is a surprise contender: 24-year-old Sahith Theegala, who is competing as a sponsor's exemption.

Theegala has a one-shot lead over Lee, though he had to finish his round while putting on his 17th hole of the day as play was suspended due to bad light.

Additionally, his next shot when he resumes in the morning will be a 16-foot putt for par, so his lead may not last for long.

A host of familiar names are not too far behind those leading the way, with Xander Schauffele, Louis Oosthuizen, Patrick Cantlay, Jon Rahm and Bubba Watson among a large group on four under.

Jordan Spieth is three shots further back.
