Briton Ian Poulter overcame a mid-round crisis to fire a one-over 72 and win the Singapore Open by one shot Sunday, finishing the $5 million event on 10-under 274 for a wire-to-wire victory. China's Liang Wenchong finished second on nine-under-par, with Australian pair Scott Hend and Adam Scott tied for third, a further shot adrift of Poulter, who won for the first time on the European Tour since the 2006 Madrid Open. The co-sanctioned event was troubled by weather delays on the three previous days but Poulter returned to the course under blue skies Sunday and battled through 30 holes before limping over the finishing line having let slip a five-shot halfway lead. On Sunday, he started the day tied for the lead with 12 holes remaining in his third round and birdied his first hole back before surrendering back-to-back bogeys around the turn to slip back to seven-under for the tournament. The flamboyant Briton parred the 11th before his round finally kicked into gear and he recorded four birdies in six holes to move back to the top of the standings. He had taken a one-stroke lead over Graeme McDowell into the final round after the Northern Irishman fired a four-under 67 and the pair were involved in a see-saw battle all afternoon. Poulter had stretched his lead over McDowell to three strokes by the time he reached the seventh fairway, but there his game suddenly fell apart when his approach to the relatively easy par-five hit a tree. He ended up taking a bogey six and was unable to drive the ball straight for the next five holes, racking up three more bogeys to slip one behind McDowell. Poulter looked hot and bothered but a straight drive on the 13th was followed by a decent approach and he drained a long birdie putt just as McDowell was starting a run of three bogeys. Back in front, Poulter regained his composure and played par golf all the way through to the finish to register his eighth European Tour victory. Liang was solid if unspectacular and tied for the lead at one stage, but his challenge faltered with a bogey on the ninth and another dropped shot on 13. “I tried my best but lady luck eluded me,” said the Chinese number one. “I just couldn't find a birdie on the 18th hole after a poor third shot. There are no regrets, however, golf is like that.” Choi picks up 2nd win Na Yeon Choi shot a 5-under-par 67 in front of her home fans to claim her second career victory Sunday on the final hole of the 2009 Hana Bank Kolon Championships in Incheon, South Korea. Choi tapped in on the 18th hole to finish at 10-under and claim a one stroke victory over Sweden's Maria Hjorth and Yani Tseng of Taiwan. Choi won the Samsung World Championships in September with an eagle after sharing the lead into the final par-5 hole. Ran Hong, who mainly plays on the Korean LPGA Tour, shot a 69 to finish four strokes off the lead, one ahead of Song-Hee Kim (71). LPGA Tour money leader Jiyai Shin of South Korea finished with a 2-under 70 to finish in lone 6th place, following yesterday's 6-over par round. America's Brittany Lang, Anna Nordqvist of Sweden, and South Koreans Se Ri Pak and Inbee Park rounded out the top-10 at 2-under tied for 7th place. Mexico's top-ranked Lorena Ochoa closed with a final round 73 to end at 6
