PITTSFORD, N.Y. – A glance at Thursday's opening round of the PGA Championship at 7,163-yard, par-70 Oak Hill Country Club (East Course):
Defending champion: Rory McIlroy, who won by a record eight strokes at Kiawah Island.
Tiger watch: Tiger Woods is 0 for 17 in the majors since winning his 14th at the 2008 U.S. Open, the longest drought of his career. But he has won five times this year, the most on the PGA Tour.
Key statistic: There have been 16 times when a player had all four rounds in the 60s at the PGA Championship, the most of any major.
Noteworthy: The last three winners of the PGA Championship have all been in their 20s, the longest such streak in any major in nearly 50 years.
Quotable: "Somebody is going to win this thing, and that person is going to play awfully well, awfully good golf this week. Wish I could say that's me." — Tom Watson, 63, playing his 32nd PGA Championship.
