Justin Thomas birdied the first two holes of a three-hole aggregate playoff against fellow American Will Zalatoris to win the PGA Championship for the second time, at the Southern Hills Country Club in Tulsa, Oklahoma.
Thomas, who also won the major in 2017, began the day seven strokes behind leader Mito Pereira of Chile.
He shot a 3-under-par 67 to finish at 5 under, a mark matched by Zalatoris.
Thomas and Zalatoris played holes 13, 17 and 18 in the playoff.
They both notched birdies on the par-5 13th and then Thomas went ahead with a birdie on the next hole.
Thomas had a tap-in par at the 18th to clinch the championship.
Pereira, who led or shared the lead for most of the final two rounds, went to the 18th tee with a one-shot advantage.
But his tee shot found a water hazard and he ended up with a double bogey and a final-round 75.
He tied for third place with Cameron Young (71) at 4 under.
Thomas wins the biggest payout of the majors, picking up $4.2 million for his victory and also receives the biggest trophy - the Wanakaer which stands 76cm tall.
The final day didn't include Tiger Woods, who withdrew for the first time in a major in an announcement that came following the completion of Saturday's third round.
Woods was 12 over and tied for 76th after the third round.
New Zealand Ryan Fox finished 54th at six over par, earning $46,000.
