(Reuters) - South Korean Chella Choi benefited from a dramatic late stumble by Spaniard Belen Mozo to take a one-shot lead after Thursday's opening round of the Manulife LPGA Classic in Cambridge, Ontario.
Mozo had been a stroke clear with one hole remaining at Whistle Bear Golf Club but the 27-year-old from Cadiz triple-bogeyed the par-four 18th to card a four-under 68 and finish two behind the new pacesetter, Choi.
American Brittany Lang, who landed her first major title in a playoff for the U.S. Women's Open at CordeValle in July, carded a 67 to end the day level with South Korea's Chun In-gee, Spaniard Azahara Munoz and Swede Dani Holmqvist.
