South Korea&aposs Jiyai Shin held her nerve to claim a comfortable victory in the Wegmans LPGA in Rochester, New York. Heading into the final round four shots clear, Shin failed to break 70 for the first time this week but a one-under effort left her on a 17-under-par total of 271. Kristy McPherson and Yani Tseng both hit last-day 66s to claim joint second on 10-under. However, Morgan Pressel, who started the round as Shin&aposs nearest challenger, crumbled and tumbled down the field with a 78. Lindsey Wright finished in a share of 15th place following a closing four-over 76 while Karrie Webb was tied for 24th at four-under overall. Meanwhile, Diana Luna was a comfortable winner of the AIB Irish Open in Portmarnock. The Italian, who took a one-shot lead into the final round, won with an 11-under-par score of 205, putting her four strokes clear of a trio of players. The 26-year-old from Rome had a bogey-free final round of four-under-par 68, enabling her to finish clear of France&aposs Gwladys Nocera (69), England&aposs Florentyna Parker and Sweden&aposs Sophie Gustafson (71). Parker finished with a round of 70, a double bogey on the 15th denying the 20-year-old Germany-born Briton a chance to put pressure on Luna in the closing holes. Gustafson, a three-time winner of this event, slipped out of contention after double bogeys on the fourth and sixth. Scotland&aposs Krystle Caithness finished fifth, a further shot back on six-under, with England&aposs Melissa Reid one behind her. Australia&aposs Frances Bondad claimed a share of 10th place at two-under while Nikki Garrett, Joanne Mills and Dana Lacey were in a large group tied for 36th at five-over. The event finished late because of two delays for fog. The final round was suspended for 30 minutes from 9.50am due to a dense sea fog which rolled in from across the Irish Sea – and there was a second suspension of more than three hours at 1pm.
