SYLVANIA, Ohio — Lydia Ko outlasted Ariya Jutanugarn and Mirim Lee to win the Marathon Classic on Sunday for her fourth LPGA Tour victory of the season.
The top-ranked Ko, 19, made a 10-foot birdie putt on the fourth extra hole after Jutanugarn and Lee ran into trouble.
"Just to see a putt drop for birdie I think kind of got my emotions going," Ko said. "I'm not really a huge fist pump kind of person, but I think it's probably the biggest fist pump I've ever done."
Also the tournament's 2014 winner, Ko closed with 2-under 69 at Highland Meadows to match Jutanugarn (68) and Lee (65) at 14-under 270. They played the par-5 18th four more times to decide the winner.
"Not a very easy hole," Ko said. "It's a dogleg left, and with the wind blowing left to right and the pin tucked on the left, it was probably the toughest it'll play. I think we were all getting a little bit physically and mentally tired as we were continuing to play the same hole."
Ko, who won her 14th tour title, entered the day three strokes behind leader Hyo Joo Kim. Kim shot 73 and finished one shot out of the playoff.
PGA: Aaron Baddeley made a 24-foot putt on the fourth hole of a playoff with Si Woo Kim to win the Barbasol Championship, Baddeley's first tour win in 51/2 years, at Opelika, Ala. Baddeley broke into a celebratory dance off the green, tossed his club in the air and flung his cap back onto the green after his fourth tour victory. He secured a two-year exemption and a spot in the PGA Championship, July 28-31, but not the Masters. After the rain-delayed third round was completed, Baddeley finished with 5-under 66 to match Kim (63) at 18-under 266.
