ST. LOUIS - Two-time US Open champion Brooks Koepka teed off in quest of his third major victory in Sunday's final round of the 100th PGA Championship with Tiger Woods in the title hunt.
Fourth-ranked Koepka, who matched the tournament record with a seven-under 63 on Friday, fired a 66 Saturday to lead on 12-under 198 after 54 holes, two strokes ahead of Australia's Adam Scott, the 2013 Masters champion and his partner in the final pairing.
Six other major winners, including 14-time major champion Woods, lurked within three strokes after an early birdie as an afternoon shootout began to unfold at Bellerive Country Club.
"Everyone is going to have to shoot low rounds," Woods said. "It's soft. It's gettable and you can't just go out there and make a bunch of pars. You're going to have to make some birdies."
There were signs low scoring was ripe for the taking with Spain's Rafa Cabrera Bello and England's Tyrrell Hatton both five-under for the day after 14 holes.
Koepka, who missed the Masters with a left wrist injury, is confident entering Sunday's showdown for the Wanamaker Trophy and a top prize of $1.98-million.
"I'm just focused on me. I feel like, if I do what I'm supposed to, I should win the golf tournament," Koepka said.
The 28-year-old American became the first golfer since Curtis Strange in 1989 to win consecutive US Open crowns in June when he defended the title at Shinnecock.
