ROCHESTER, New York –

Six weeks after squandering a final-round lead at the Masters, Brooks Koepka made the most of his second chance with a PGA Championship triumph on Sunday to claim his fifth major, something that seemed unlikely when he joined LIV Golf last year after injuries sidetracked his career.

Koepka, who endured a two-year stretch where he was plagued by injuries and underwent multiple knee surgeries, which played a role in his decision to join LIV Golf last June, made no secret about where his latest triumph ranks.

"This one is probably the most meaningful of them all with everything that's gone on, all the crazy stuff over the last few years," said Koepka, who is the first player to win a major championship while a member of LIV Golf.

While Koepka's two-shot victory over world No. 2 Scottie Scheffler and Norway's Viktor Hovland was a landmark win for LIV Golf, it also reaffirmed the 33-year-old American's belief that he can close out a major.

At last month's Masters, Koepka took a two-shot lead into the final round but saw it vanish after four holes and went on to a runner-up finish that he insisted taught him a valuable lesson — one he is not willing to share.

"I definitely wouldn't have, I don't think, won today if that didn't happen," Koepka said.

"Definitely take it and keep using it going forward for each event, each major, any time I'm in contention, but I'm not going to share. I can't give away all the secrets."

Koepka was dominant the last three days, firing the low score in the second and third rounds to put himself in position to avenge his Masters letdown.

The former world No. 1 was dialed in early and made three consecutive birdies to open up a three-shot lead over Hovland after four holes.

By the time he reached the 16th, Koepka was clinging to a one-shot lead but made a birdie that, coupled with a double-bogey from Hovland after the Norwegian plugged his second shot into the lip of a bunker, gave him a four-shot cushion.

While Koepka would surely have loved to have played as solidly in the final round at Augusta National, he knows that result made him stronger.

"Failure is how you learn," Koepka said. "You get better from it. You realize what mistakes you've made."

Through the first two majors of the year, Koepka has resembled the dominant figure he was when he collected four major titles from 2017 to 2019.

Koepka's latest triumph makes him the 20th player in history with five major victories and fully aware of what needs to be done when he tees it up at next month's U.S. Open.

"Keep doing what I'm doing. It's working so far. Back to having a chance pretty much every time I tee it up," Koepka said. "So I'm very pleased with the way I'm playing. I like the way I've worked with everybody. It's been a lot of fun."
