The playoff will start on the par-5 13th, move to the short par-4 17th and then finish at the par-4 18th.
Justin Thomas and Will Zalatoris will play a three-hole aggregate playoff to determine the 2022 PGA champion at Southern Hills.
They'll start on the par-5 13th, move to the short par-4 17th and then finish at the par-4 18th. If still tied, it will be a hole-by-hole playoff on 18-13-17-18.
The playoff was created when leader Mito Pereira double-bogeyed No. 18, sending his opening tee shot into the water and failing to get up and down from a difficult spot on the edge of the green. That allowed Zalatoris, who began the day tied for second place, and Thomas, who surged up the leaderboard with a 67 (tying the low round of the day), to meet in the playoff.
Zalatoris is searching for his first major championship and PGA Tour win. Thomas has one previous major championship, the 2017 PGA.
This is the first playoff in a men's major championship since the 2017 Masters between Sergio Garcia and Justin Rose. The gap of 19 majors between playoffs is the longest drought in the men's game since the PGA Championship went to stroke play in 1958.
