May 16 (UPI) -- Brooks Koepka sat at the top of the leaderboard on Thursday at the 101st PGA Championship, coasting through a bogey-free round of 63 that set the course record at Bethpage Black.
Koepka, who also shot 63 on his way to winning the PGA Championship last year in St. Louis, had seven birdies and posted the lowest opening round by a defending PGA champion. He joined Greg Norman and Vijay Singh as the third player ever to record multiple rounds of 63 in major championship history, according to 15th Club.
