QUARTERFINAL UPDATES (All times ET)
5:53 p.m. – Lee Westwood or Rory McIlroy could take over world No. 1 should they go on to win on Sunday. Westwood isn’t concerned with anything but his semifinal, though, telling PGA TOUR Radio: “The winner of that match gets to play in the finals with a chance to win the tournament. That’s all I should be thinking about.”
5:49 p.m. -- Lee Westwood has beaten Martin Laird 4 and 2 to set up a semifinal match with world No. 2 Rory McIlroy. Laird conceded Westwood’s 2-footer for par at the 16th hole after the he was unable to save from 11 feet.
5:37 p.m. – Lee Westwood and Martin Laird halved the 15th hole with birdies so that match is dormie. The Englishman, ranked No. 2 in the world, is 3 up with three holes remaining.
5:32 p.m. -- Rory McIlroy has beaten an extremely game Sang-moon Bae 4 and 2. McIlroy hit his tee shot at the par-3 16th 51 feet from the pin while Bae found the greenside bunker. McIlroy put his second 23 inches from the pin and when Bae couldn’t hole his bunker shot, he conceded.
5:28 p.m. – Lee Westwood has gone 3 up with four holes remaining in his match with Martin Laird. The Scotsman conceded after leaving his second shot in a greenside bunker and blasting out to 5 feet for a potential par. Westwood, meanwhile, had driven just in front of the green, 22 feet from the pin.
5:25 p.m. – Rory McIlroy played another brilliant chip at the 15th hole to 3 feet for a birdie that lifted him to 3 up on Sang-moon Bae with three holes remaining. Bae also missed the green at the driveable par 4 but was unsuccessful on the ensuing 23-footer for birdie.
5:12 p.m. -- Sang-moon Bae had a shot to cut into Rory McIlroy's lead at the 14th hole after the Northern Irishman missed a 9-footer for birdie. But Bae was unable to convert his own 8-footer so the margin remains 2 up in McIlroy's favor.
5:10 p.m. -- After a 358-yard drive at the par-5 13th hole, Martin Laird put his second shot to 14 feet for eagle. He couldn’t convert the golden opportunity, though, and Westwood got up and down from in front of the green to halve, making the 7-footer for birdie to stay 2 up.
5:03 p.m. -- Sang-moon Bae, whose tee shot at the 13th settled under the lip of the right fairway bunker and his second veered into the desert, was beside the green looking at a chip to save par when Rory McIlroy blasted out of a greenside bunker to 22 inches for a tap-in birdie. Bae conceded and McIlory is now 2 up.
