Derek Ernst pips David Lynn in Wells Fargo Championship play-off at Quail Hollow Ernst was fourth reserve at the start of the week and only played because of all the withdrawals, which came due to the awful state of the greens in Charlotte, North Carolina. Ranked 1,207th in the world, Ernst, a 500-1 outsider at the start of the event, was one of the most unlikely winners in golf's history - and for that reason Lynn might be kicking himself. He was also playing with Lee Westwood, who joined Mickelson in the lead after birdieing the 10th. But back-to-back bogeys on the 12th and 13th essentially ended his challenge. Westwood, who has been suffering from a chest infection, eventually signed for a level par to emulate his finish from last year, a tie for fifth, on six-under. Rory McIlroy endured a wretched weekend as his 73-73 finish left him down in a tie for 10th on four-under. The Ulsterman will take great hope from his ball-striking, however, and, at the very least, will be optimistic of laying to rest his Sawgrass curse. He played The Players three times and missed the cut every time. On the European Tour, Brett Rumford did "a London bus" by following up last week's win in Korea with victory in the Volvo China Open. The 35-year-old Australian had not prevailed for six years before the Ballantine's Championship, but the manner of his 16-under success - beating Finland's Mikko Ilonen by four shots - suggests this is a run with legs. "As with last week, I am kind of speechless at the moment, it's quite surreal," Rumford said. It's really hard to try and go back-to-back, it's the first time I've actually played the week after a win so I am more than pleased. It's quite a feat, it's very special. Ye Wo-cheng, the 12-year-old Chinese who became the youngest golfer to play a European Tour event, missed the cut after two rounds of 79.
