- Thailand's Ariya Jutanugarn drained a 25-foot birdie putt to win the Manulife LPGA Classic in a three-way playoff, guaranteeing her ascent to the world number one ranking. Her dramatic win at Whistle Bear Golf Club in Cambridge, Ontario came after Lexi Thompson stumbled with four bogeys on the back nine which saw a four-shot lead evaporate. On the first playoff hole, Thompson looked to have recovered her composure when she crushed a long tee shot 50 yards further than Ariya and South Korea's Chun In-Gee. Ariya, who had underhit her tee shot into the fairway rough, hit her second onto the green. Both Chun and Thompson then missed long birdie putts leaving Ariya with her shot at glory which she duly converted. The result capped a rollercoaster week for the 21-year-old from Bangkok, who had wrongly been informed by the LPGA last week that she had taken the world number one ranking from Lydia Ko.
