Horschel jumps into lead, McIlroy stumbles

CHERRY HILLS VILLAGE, United States, Sept 7 (AFP): Billy Horschel, who is determined to put Monday's tough finish fast behind him, fired a third-round 63 to vault three shots clear of the field at the BMW Championship.

Horschel capped his bogey-free round at the Cherry Hills Country Club by rolling in a 32-foot birdie putt on No. 18.

It was a far cry from his final hole at the Deutsche Bank Championship Monday when he chunked his second shot well short into the hazard and had to settle for a bogey.Horschel finished in a tie for second place after having arrived at the 18th tee just one shot behind winner Chris Kirk.

"I was over it real quickly," Horschel said. "It was just a bad swing at the wrong time.

Tell that to world number one Rory McIlroy, who suffered the ignominy of a triple-bogey in his third round.

McIlroy's assault threatened to dissolve as he four putted on the par-three 12th. The Northern Irishman ended up posting a 72, which dropped him into a tie for 10th at four-under 206.

McIlroy joked about his triple-bogey wobble on Twitter.

"Glad everybody enjoyed my 4 putt today... always tomorrow to get a few shots back and get up that leaderboard!" he said.
