Sun Young Yoo birdied the first playoff hole to win the LPGA Kraft Nabisco Championship on Sunday after I.K. Kim missed a one-foot putt for the win on the final hole of regulation. Yoo was steady down the stretch in the first women’s major championship of 2012, but it was only Kim’s heartbreaking miss that made her playoff triumph possible. “She’s a great putter,” Yoo said of Kim. “She usually doesn’t miss that kind of putt, but … in sports, you never know what’s going to happen.” Both South Koreans carded final-round 69s to finish 72 holes tied on nine-under 279. Kim could have sealed a victory at 10-under with her tap-in for par at the par-five 18th, but it circled the rim of the cup then popped out. It was her only bogey in a round that included three birdies and drew a gasp from the gallery. She put her hands to her face in dismay, then walked eyes down to the scorers’ tent.
