MARANA, Ariz., Feb. 25 (UPI) -- Rory McIlroy
will take on Lee Westwood
in one semifinal round of the WGC-Accenture Match Play Championship after each won quarterfinal matches Saturday.

McIlroy, the top seed in the Gary Player bracket, bested 11th-seeded Sang Moon Bae, 3 & 2 Saturday.
Meanwhile, Westwood -- the No. 1 seed in the Sam Snead bracket -- posted a 4 & 2 victory over Martin Laird.
A pair of Americans will compete against each in the other semifinal battle after each registered a victory in the quarters.
Hunter Mahan drubbed Matt Kuchar 6 & 5 in one of the matches, capturing the Ben Hogan bracket.
He will face Bobby Jones bracket champ Mark Wilson, who took a 4 & 3 win over Peter Hanson.
The championship round will follow the Sunday morning semifinals.
