CHARLOTTE, N.C. (AP) A brief look at the first round of the PGA Championship (all times EDT):
LEADING: Thorbjorn Olesen and Kevin Kisner, who both were at 4-under 67.
JUST BEHIND: Five players were a stroke back - Grayson Murray, Gary Woodland, Brooks Koepka, Chris Stroud and D.A. Points.
QUEST FOR THE SLAM: Jordan Spieth began his chase for the career Grand Slam with a 72 during which the accomplished putter didn't make one from longer than 5 feet.
SHOTS OF THE DAY: Both Olesen and Kisner closed their rounds by making long birdie putts on the par-4 18th, with Kisner holing a 20-footer and Olesen walking off with a 30-footer.
NOT A HAPPY 100TH: Phil Mickelson's 79 marked his worst round ever at a PGA Championship, while Ernie Els matched his worst score in the championship with an 80. Both are playing in their 100th major.
NOTEWORTHY: The course played to an average score of 74.7, making it look like the toughest test of this year's majors. The 506-yard, par-4 16th hole yielded the fewest birdies (six).
QUOTEWORTHY: ''That's never fun to walk up and see somebody, you just drilled them. I drilled him in the head, which is probably the worst part. To be honest with you, I felt like crap.'' - Brooks Koepka, who hit a marshal with his drive on No. 16. A PGA of America official said the marshal was fine but went home for the day.
