Justin Thomas ultimately prevailed in a thrilling US PGA Championship, lifting the Wanamaker Trophy after Mito Pereira's collapse on the 18th hole forced a playoff.
Holding the lead coming into the final round, Pereira only needed a par on the 18th hole to secure his first PGA Tour victory, but put his drive in the water and could not even salvage a bogey to earn his spot in the playoff.
With a double-bogey capping off a final round 75, he went from six under to four under, tying for third with Cameron Young.
The playoff was contested between Thomas and Will Zalatoris after both players produced clutch shots late in their rounds to finish at five under.
Thomas – who tied for the round of the day with his 67 – had a birdie putt on 18 to move to six under, but could not convert from 10 feet, finishing with a par to head into the clubhouse in outright second place, trailing Pereira by one shot.
Zalatoris, on the other hand, bogeyed the 16th to drop to four under, but came right back with a birdie on 17. He had a tricky par putt on 18 to remain tied with Thomas, and he remained cool under pressure.
In the playoff – which was contested over the aggregate score of three holes, the first being a par-five – Zalatoris appeared to strike first as he found the fairway with his drive, while Thomas hit the rough. Thomas was forced to lay-up, while Zalatoris made the green in two.
Zalatoris two-putted for his birdie, while Thomas put his wedge to within six feet, converting his birdie putt to tie the first playoff hole.
The second playoff hole was the 17th – a drivable par-four – and Thomas found the green with his drive. Zalatoris did not, and after chipping into birdie range, he missed his putt, tapping in for par. Thomas, on the other hand, safely two-putted for birdie to take a one stroke lead into the final playoff hole.
Both players drove well and made the green in regulation on the last, and after Zalatoris failed to sink a long birdie putt, Thomas only needed to two-putt for par to secure his second career major, making no mistakes. It is his second PGA Championship, five years after winning at Quail Hollow.
Also making the top-five was the English duo of Matt Fitzpatrick and Tommy Fleetwood – with the latter matching Sunday's best score – and American Chris Kirk, tied for fifth at three under.
It was a strong final round from Rory McIlroy, who rebounded from a disappointing 74 on Saturday to shoot 68 – one stroke off the round of the day – to finish outright eighth at two under.
McIlroy looked like he may be trending for a legendary final round after four consecutive birdies starting on the second hole, but he would claim no more from the fifth.
A four-man group of Mexico's Abraham Ancer, Ireland's Seamus Power and the American pairing of Tom Hoge and Brendan Steele rounded out the top-10, and the last players to finish under par.
Cameron Smith and Xander Schauffele highlighted the group at even par, while the big names struggled, as Jordan Spieth finished at four over, Jon Rahm wrapped up at six over, and Collin Morikawa at eight over.
Shot of the day
The shot of the day went to Englishman Laurie Canter, who birdied the difficult par-four 18th hole from the fairway.
After his drive found the rough, he was forced to lay-up 97 yards from the pin, but was able to convert it thanks to some sharp backspin.
A little birdie told me…
Before his horror drive on 18, Pereira earned his 71-hole lead with great success on the difficult par-fives and par-threes. He joined Webb Simpson as the only players to shoot a combined six under on the par-fives (fifth and 13th holes) over their four rounds
Only four players finished under par for the week on the par-threes (sixth, eighth, 11th and 14th holes) – Fitzpatrick and Rose were two under, while Pereira and Steele shot one under.
On average, nobody drove the ball further than Rory McIlroy this week, posting 347.6 yards per drive. However, the longest drive of the week went to Jon Rahm, with a 418-yard bomb.
