ATLANTIC CITY (New Jersey) (AFP) Japans Ai Miyazato fired a seven-under 64 Sunday to win the 1.5 million dollar LPGA ShopRite Classic for a No. 1 ranking and her fourth win of the season. The 25-year-old Miyazato is guaranteed to take over the number one position when the womens golf rankings are issued on Monday. When I started playing in the States, thats when I really started thinking about being No. 1, Miyazato said. That became a dream of mine, especially watching Annika (Sorenstam) and Lorena (Ochoa) play. Now that I am No. 1, I still cant believe it, but I do feel very comfortable with it. Second-round leader MJ Hur of South Korea placed second, two shots adrift of Miyazato, who turns 25 on Saturday. South Korean compatriot Park Inbee was a further two shots back. Park is the 2008 US Womens Open champ. Norways Suzann Pettersen, South Koreas Han Hee-Won and Katherine Hull of Australia shared fourth place at 11 under. Miyazato began the final round two shots back. She needed only three holes to grab a share of the lead, finishing with seven birdies in a bogey-free round that gave her a 54-hole total of 16-under 197. I believe in myself and the game and no matter what the situation is or the pressure is I feel like I can play my game, said Miyazato. It was Miyazatos fifth career win on the LPGA Tour but first on US soil. She won earlier this year in Thailand, Singapore and Mexico. Her victory last year came in France. She earned 225,000 dollar in first place prize money. The win vaults her past South Koreas Shin Jiyai into top spot in the rankings. Shin has missed the last two tournaments after undergoing an appendectomy. Hur said she was pleased for Miyazato. Shes just gorgeous, said Hur. She hits straight and has good putts, so I think she plays really simple. I want to be playing that, too.
