Because it lacks a distinct identity, the PGA Championship is like the ugly stepsister of the majors, particularly when it’s at a mishmash of a U.S. Open-wannabe course (circa 1980s) like Oak Hill, with lots of trees and high rough. The latter is extra juicy, too, because of all the rain this summer. Give us Kiawah or Whistling anytime. In five previous majors here, a total of only 10 players broke par over 72 holes. This year the layout will play to a par 70 of 7,163 yards with the ultra tough 17th and 18th par fours both lengthened to pretty much ensure no one birdies them. Despite the slog of a course, all could be saved if the cream rises and the world’s No. 1 and 2 players, Tiger and Phil, are in the final Sunday grouping for the first time in a major since the ’09 Masters. That’s a big if, though, given that a little-known player, Shaun Micheel, outdueled a somewhat lesser little-known player, Chad Campbell, here the last time in 2003. On the good side, at least the weather forecast is good with sunny skies and temps in the 70s.
