Leaders Peter Lawrie and David Drysdale each shot 6-under 66s Thursday at the BMW PGA Championship, leaving a frustrated top-ranked Rory McIlroy and his high-ranking rivals trailing after the first round.
McIlroy had five bogeys and a double bogey in his round of 74 to go with three birdies and an eagle. On the par-5, 12th he hurled his club after a poor provisional shot, which came after he sent his second shot out of bounds en route to a bogey 6.
''It's pretty disappointing,'' said McIlroy, whose No. 1 ranking is under threat from Luke Donald this week. ''I feel like I'm playing well, I just need to go out there and shoot a score.''
Lawrie had four birdies and an eagle in an error-free round and the 291st-ranked Drysdale had seven birdies and a bogey in good weather at Wentworth.
Jamie Donaldson and Justin Rose had 67s, while second-ranked Donald joined a group two shots back after a 68.
McIlroy could be fined should his actions be deemed against the European Tour's guideline...
