Katherine Hull fired a three-under-par 69 to win the LPGA Canadian Women's Open by one stroke on Sunday. South Korea's Pak Se-ri was second just one shot behind Hull who finished at 11-under 277 total. Taiwan's Yani Tseng entered the day with a four-stroke advantage but she collapsed in the final round with five bogeys and a double bogey to shoot a 77 to finish in third place. Hull had three birdies on the front nine and added one more coming in. She had just one bogey, playing steady golf while Pak and Tseng did anything but. Pak birdied the final two holes for an even-par 72, but was just not able to overcome her mistakes. She bogeyed Nos. 4 and 5 and then carded a double-bogey at the par-5 sixth. She had three birdies in four holes starting at the seventh to get back in the hunt but a bogey at 16 ultimately left her a little short. Michelle Wie closed with a 71 to finish tied for 12th at three-under. Pettersson claims crown In North Carolina, Sweden's Carl Pettersson shrugged off a mid-round slump to secure a two-stroke victory over Scott McCarron at the Wyndham Championship on Sunday. The North Carolina-based player surrendered the lead with soft bogeys at the 10th and 11th holes before roaring back to edge out his American playing partner at Sedgefield. The overnight leader carded a 68 to finish on a tournament-record 21-under-par 259, while McCarron shot the same score for a 19-under finish, with Rich Beem (63) two shots further back in third place. Pettersson is the third Swede to win on the North American this year, joining Daniel Chopra (Mercedes Championship) and Richard Johnson (Milwaukee), and the second to win in Greensboro, after Jesper Parnevik (1999). The Swede still remains a long shot to make the European Ryder Cup team automatically but his performance brings him into contention for one of the two captain's picks that Nick Faldo will make in two weeks. Pettersson left Sweden for England at the age of 10, and moved to Greensboro at 15 when his Volvo executive father was transferred to the city. He admits to feeling more American than European but would love to play for Europe at next month's Ryder Cup in Kentucky. “I know I'm Swedish but I really feel American,” he said. “But my heritage is European and I would love to play on Nick's team. I might be a little different but I'm going to be playing hard for Europe if I make that team.” Defending champion Brandt Snedeker had a weekend to forget, the American following up a 74 with a 70 to finish 19 shots of the lead and ahead of only four other players that made the cut.
