The Green Mile nearly sent Masters champion Rory McIlroy home early from the PGA Championship. Quail Hollow's closing three holes known did a number on several other players, too.
The Green Mile has lived up to its diabolical reputation this week as one of the most difficult closing stretches in golf and has had a major impact on the leaderboard. In short, if you can navigate the Green Mile in par, or close to it, you're probably playing well.
If you don't your fortunes can change quickly.
McIlroy's nearly did.
The world's No. 2 player and recent Masters champion was looking to make a move up the leaderboard late in the second round Friday after pulling within seven shots of leader Jhonattan Vegas.
