So Yeon Ryu, of South Korea, drives from the ninth tee during the final round of the Jamie Farr Toledo Classic golf tournament at Highland Meadows Golf Club in Sylvania, Ohio, Sunday, Aug. 12, 2012.

SYLVANIA, Ohio — So Yeon Ryu rode a string of six straight birdies in the middle of her round to a 9-under 62 and a seven-stroke victory Sunday in the Jamie Farr Toledo Classic.

The 22-year-old began the day in the midst of a four-player logjam — all South Koreans — for first place. She took the lead by herself for the first time with an 8-foot birdie putt at the third hole and gradually stretched her advantage until pulling away with birdies on Nos. 9-14.

Angela Stanford made a long birdie putt on the final hole for 66 to finish second.

Ryu, whose only previous LPGA Tour win was the 2011 U.S. Women's Open, ended up at 20-under 264 — thanks to the lowest final round by a Farr winner.
