American Paula Creamer followed up her opening-round course record 60 with a final round two-over 73 to hang on and capture the LPGA Jamie Farr Classic on Sunday. The 21-year-old American finished with a 16-under 268 total to beat Nicole Castrale by two strokes at the 1.3 million dollar tournament. “It's always difficult to lead from start to finish. There is so much pressure,” said Creamer, after picking up her third title of the season and the seventh of her four year LPGA Tour career. Creamer went into the final round with a four-stroke lead and had to hold off late challenges from Castrale, who fired a eight-under 64 in the final round, and Chinese rookie Feng Shanshan. Castrale finished with a flourish, rolling in six birdies on the final eight holes. Creamer made three bogeys and had one birdie Sunday at the Highland Meadows Golf Club. Creamer had 18 birdies over the first two rounds when she posted scores of 60-65, but she managed only four over her final 36 holes. South Korea's Ji Eun-hee finished third with a 72, three shots back of Creamer. Feng shot a two-under 69 to grab sole possession of fourth with a 12-under 272 total. Feng also made a charge on Sunday with five birdies through the first 11 holes but then stumbled on the back nine by making three consecutive bogeys beginning on hole No. 14. It marked her first top 10 finish on the LPGA in 14 tournament starts this year. She picked up over $65,000 for finishing fourth - more than three times her total earnings in 2008 heading into the tournament. McDowell triumphs Graeme McDowell warmed up in style for Thursday's British Open by securing a two-shot victory at the Scottish Open, his second European Tour triumph of the season. The 28-year-old from Northern Ireland fired a closing 68 for a 13-under tally of 271, with Sunday's first prize of £500,000 ($1 million) all but clinching his place in the Ryder Cup team to face the US in Valhalla, Kentucky in September. South African James Kingston (66) was second on 273, one ahead of order of merit leader Miguel Angel Jimenez (69) of Spain and Australian left-hander Richard Green (69). Briton Simon Khan (72), the joint overnight leader with McDowell, claimed the penultimate qualifying spot for the British Open at Royal Birkdale by finishing fifth on 275. Britain's Stephen Gallacher, nephew of former Ryder Cup captain Bernard, and Alvaro Quiros of Spain sprinted through the field with matching seven-under-par 64s. Scot Gallacher, cheered on by his local crowd, struck the ball with real aplomb as seven birdies gave him an eight-under total of 276. Quiros, who also did not drop a shot all day, grabbed four birdies in the last six holes to finish on 277, the same mark as twice former winner Ernie Els. World number three Adam Scott's title chances disappeared with two successive double bogey sixes at the ninth and 10th as he finished with a 74 for 280. Second-ranked Phil Mickelson carded a 73 for 282. Third win for Perry American Kenny Perry won a three-way play-off to win the John Deere Classic at Silvis, Illinois Sunday and claim his third win in his last five PGA events. Perry went into the final hole with a one-shot lead but made a hash of a chip to the green and bogeyed the 18th to leave him in a three-way play-off with Brad Adamonis and Jay Williamson. The 47-year-old Perry kept his cool in the play-off, making a par while his two rivals found water and bogeyed. Williamson's finish was enough to earn him an invitation to next week's British Open.
