Victory for McIlroy over Woods would bring him $450,000 in prize money. Even a loss to the 14-time major winner will carry a $300,000 check.
In other morning matches, Rose defeated Westwood with a round of 66 to his European Ryder Cup teammate's 69. Simpson, the U.S. Open champion, had a 65 to Mahan's 67 for his first victory, leaving his fellow American winless.
The event is sponsored by Turkish Airlines, with the winner earning $1.5 million.
