(Reuters) - Rory McIlroy's roller-coaster opening round at the Tour Championship on Thursday was not ideal for stroke play but just about perfect for the match play format of next week's Ryder Cup. Northern Irishman McIlroy is the only member of the European Ryder Cup team in the 30-man field at East Lake in Atlanta, where eight players from the United States lineup are in action ahead of next week's showdown in Chaska, Minnesota. "When I get it going, I can really run with it and then when it goes the other way I struggle to get out of it a little bit but that's the nature of the way my game is right now, and how it has been for most of the year," McIlroy told reporters after carding a two-under 68 that left him two strokes off the lead.
