Three Peat, Lydia Ko / Getty Images Teenage Kiwi Lydia Ko has received the McCormack Medal as the world's leading women amateur for a third straight year. The medal was presented by the Royal & Ancient and United States Golf Association on Wednesday. Sixteen year-old Lydia successfully defended the Canadian Women's Open title on the LPGA Tour, then finished runner-up at the Evian Championship, the year's last major. Other highlights include a tie for third in the Australian Women's Open, and tie for 17th in the LPGA Championship. According to reports Lydia will play in the season-ending CME Titleholders in November as a professional. She is already a two-time winner on the LPGA, and hinted at such a move at the Evian Championship last month, where she finished runner-up to Suzann Pettersen. Tina Hyon, Lydia's mother, told Golf Channel on Wednesday that she will play the Titleholders in Naples, Fla., and might even compete in the Lorena Ochoa Invitational the week prior. Lydia will need to receive permission from LPGA commissioner Mike Whan to compete on the LPGA prior to her 18th birthday. The Kiwi sensation will not turn 17 until April 24 next year. She is currently world-ranked No 5.
