(Reuters) - Jang Ha-na of South Korea overcame a back injury to make five birdies on the last nine capped by one at 18 for a five-under 66 and a one-shot lead after the opening round of the LPGA Marathon Classic in Sylvania, Illinois.
Tour rookie Jang played while dealing with an injury that forced her to finish her swing with one hand off the club and caused her to bypass hitting warm-up shots and consider withdrawing from the event.
"Today my back really bad," said Jang, who had hit two full clubs extra into the greens for much of the round.
