TULSA, Okla. — The dominant story line before the 2022 PGA Championship revolved around Phil Mickelson, who became the oldest major champion last year when he won the event at age 50 but chose not to defend his title. Then the focus of the tournament shifted to Tiger Woods, 46, who arrived at the Southern Hills Country Club to resume his stirring comeback from injuries he sustained in a horrific car crash 15 months ago. But Woods struggled physically, and mired in last place after three rounds, he withdrew before Sunday's final round.
What evolved instead on the last day of the PGA Championship was a glimpse of elite men's golf's youthful future, not its aging past. On a nervy, topsy-turvy afternoon in eastern Oklahoma, there was yet another dramatic showdown between the dazzling, hard-swinging 20-somethings who have overtaken the game.
In a taut, three-hole aggregate playoff after the 18-hole fourth round ended in a tie, Justin Thomas, 29, held off the 25-year-old rising star Will Zalatoris to win his second P.G.A. Championship. The last four winners of golf's major championships, Thomas; Scottie Scheffler, at the Masters; Collin Morikawa, at the British Open; and Jon Rahm, the reigning U.S. Open champion, are in their 20s.
Even in defeat, Zalatoris briefly laughed as he assessed how his generation had become dominant so quickly.
"I kind of have to check myself sometimes because I feel like I'm playing junior golf and college golf all over again," Zalatoris said, mentioning his longtime rivals Scheffler, Thomas and Mito Pereira, 27, who held the lead for most of the fourth round. "We've been playing together for almost 10 years. Now we're at the highest level of golf."
Thomas, who began the final round seven strokes off the lead, did not figure to be celebrating a victory after his first eight holes Sunday when he was one over par. His final-round rally tied for the third-largest comeback in major championship history.
"It was a bizarre day, no doubt," Thomas, who also won the 2017 PGA Championship, said. "But I said in a news conference before the first round that no lead would be safe here — too much wind and too many scary holes."
Pereira, the third-round leader, had appeared poised to become the first golfer from Chile to win a major golf championship. Stepping to the 18th tee Sunday evening, he was playing in the final group and needed only a par to clinch the title.
