Top-ranked Rory McIlroy had five bogeys and a double bogey in his round of 74 to go with three birdies and an eagle.
Graeme McDowell was left to bemoan the sometimes obscure rules of golf after he was docked two shots on the last hole in a "freak" scenario.
The former U.S. Open champion was on course to break par when he approached the ball after hitting his drive into the bushes to the right of the fairway.
The ball, which was lying on a bed of branches, moved slightly -- costing him a shot -- and because he didn't replace it, he was handed another penalty stroke by the European Tour referee.
The triple-bogey 8 wrecked his round as he finished with a 2-over 74.
"The rules of golf are very precise and in-depth -- it's impossible to know every idiosyncrasy of them," McDowell said.Information from The Associated Press was used in this report.
