CHARLOTTE, N.C. (AP) - Quail Hollow wasn't very kind to the 155 competitors in the opening round of the PGA Championship.
Kevin Kisner and Thorbjorn Olesen share the lead after shooting 4-under 67s. It's the highest score to lead after the first round of the PGA Championship since Matt Kuchar shot 67 at Whistling Straits in 2010.
Fast, unforgiving putting surfaces were a major reason for the high scores.
Kisner birdied three of his final five holes, including a 20-footer on 18. Olesen finished with a 30-foot birdie.
Reigning U.S. Open champ Brooks Koepka is among five players at 3 under. Koepka missed a half-dozen putts from 12 feet or closer.
Americans Grayson Murray, Gary Woodland, Chris Stroud and D.A. Points also find themselves at minus-3. Rickie Fowler and Hideki Matsuyama are in a mix at 1 under.
Jordan Spieth opened with a 72 as the 24-year-old tries to become the youngest to win a career Grand Slam. Rory McIlroy also signed off on a 72.
Phil Mickelson struggled in his opening round, finishing with an 8-over 79 that puts him in danger of missing the cut at a PGA Championship for the first time since 1995. It was the worst round of his 25 appearances at the final major of the season.
