American Kenny Perry claimed his second title of the year when Woody Austin bogeyed the final hole to hand him victory at the Buick Open on Sunday. With Perry in the clubhouse signing for an adventurous final round 66, Austin's title hopes ended with a bogey-bogey finish, missing an 18-foot par putt at the 18th to force a playoff. It was a crushing defeat for Austin, who had mounted a charge with birdies at 12, 13, 14 and 16 to get into contention before his collapse left him with a four-under 68 and tied for second on 18 under with Bubba Watson. Watson also had a chance to force a playoff but left a 12-footer inches from the hole. Perry also endured a rollercoaster finish at Warwick Hills Golf and Country Club with a bogey, eagle, bogey, birdie stretch from the 13th but held on for a one-shot victory with a total of 19-under 269. Americans Bob Tway (65), Ken Duke (67) and Australia's Matt Jones finished one shot further adrift at 271. Inbee seals victory South Korean teenager Park Inbee, maintaining her poise in blustery conditions, became the youngest player to win the US Women's Open with a four-shot victory at Edina in Minnesota on Sunday. Two strokes off the pace going into the final round at Interlachen Country Club, the 19-year-old birdied the first two holes on her way to a two-under-par 71. With most of her closest challengers floundering in the gusting winds, Inbee eased to her maiden LPGA Tour title, eclipsing compatriot Pak Se-ri who won the tournament in 1998 aged 20. American Morgan Pressel was 18 when she won last year's Kraft Nabisco Championship and Taiwan's Yani Tseng triumphed at this month's LPGA Championship at 19. Veteran Swede Helen Alfredsson birdied the final hole for a 75 to secure second place at five under. Surprise overnight leader Stacy Lewis closed with a 78 to tie for third with Korean Kim In-kyung (75) and Brazil's Angela Park (73).
