Lewis had a pair of bogeys but piled up the birdies, including closing with three straight, for an 8-under-par 64 Sunday and 54-hole total of 205. It was the fourth tournament title this year for Lewis and fifth as a professional. She also won the LPGA event in Arkansas in 2007 as an amateur.
The birdie binge allowed her to edge second-round leader Lee Bo-mee by one stroke. Lee, who had a 64 Saturday, was even par 72 Sunday and 10-under for the tournament. First-round co-leader Ayako Uehara turned in a final-round 67 and was 9-under overall while world No. 1 Yani Tseng had a 68 Sunday for a tournament total of 7-under 209.
Lewis opened the final round seven back of Lee but started her climb with birdies at the first two holes. She was still 2-under after a bogey at the third hole and a birdie at No. 4. A seventh-hole birdie allowed her to make the turn at 3-under.
She birdied 10 but gave that back with a 4 at the par-3 11th hole.
Lewis, however, closed with five birdies over the final seven holes. She had birdies at 12 and 13 before the run of three consecutive birdies in the last three holes.
That gave her the lead over Lee, who still had three holes to go but Lee had pars the rest of the way and settled for second.
