TOKYO – South Korea’s Ahn Sun-Ju displayed nerves of steel to capture her first LPGA title on Sunday by winning the $1.5 million TOTO Japan Classic in a three-way playoff. The 28-year-old calmly sank a five-foot birdie putt on the first playoff hole after finishing the 54-hole tournament tied with a 16-under-par total of 200 alongside fellow Korean Lee Ji-Hee and American Angela Stanford. A superb six-iron approach from 165 yards set up Ahn’s coup de grace on the first extra hole after firing a final-round 67 in drizzly conditions at the Kintetsu Kashikojima Country Club in Mie prefecture, western Japan. “I didn’t think I could win the tournament but it’s a nice surprise,” said Ahn after her 27th professional win, the bulk of them coming on the Japanese tour. “I’m so happy.”
