Japan's Ai Miyazato shot a 7-under 64 Sunday to win the $1.5 million ShopRite LPGA Classic.
The 25-year-old Miyazato is guaranteed to take over the No. 1 spot in Monday's rankings after her fourth victory of the season.
Second-round leader M.J. Hur finished second, two shots behind Miyazato. Fellow South Korean Inbee Park, the 2008 U.S. Women's Open champion, was a further two shots back.
Suzann Pettersen of Norway, South Korea's Hee-Won Han and Katherine Hull of Australia shared fourth place at 11 under, one shot ahead of Paula Creamer, who had a spectacular return in her first tournament since surgery on her left thumb in March.
Miyazato opened the final round two shots back and needed only three holes to grab a share of the lead. She finished with seven birdies in a bogey-free round that gave her a 54-hole total of 16-under 197.
The win was Miyazato's fifth on the LPGA Tour, but her first in the United States. She won earlier this year in Thailand, Singapore and Mexico. Her victory last year came in France.
The winner's prize was $225,000, pushing Miyazato's earnings this year to $830,238.
She will replace Jiyai Shin of South Korea atop the rankings. Shin has missed the last two tournaments after undergoing an appendectomy.
Shin took over the top spot after Mexico's Lorena Ochoa retired earlier this year to focus on starting a family.
