ARDMORE, Pa. -- Only two players are under par at the moment at Merion, but Tiger Woods and Rory McIlroy are still losing ground.
Woods made the turn in 2 over, McIlroy in 3 over and they are now six and seven shots off the lead, respectively.
Things looked promising early on for the top two ranked players in the world with each making birdie on the opening hole.
But then McIlroy hit his tee shot out of bounds on the par-5 second, and Woods managed just a par after a poor wedge shot that came up well short of the hole on his approach.
Woods then bogeyed three of the next four holes with his chipping and putting looking a lot like it did a couple of years ago than it has in four wins this season.
McIlroy, meanwhile, bogeyed four of his next five holes after the early birdie, then added one more bogey on No. 9.
