who had led much of the tournament

Webb managed to overcome an overnight one-shot deficit to win the tournament by a stroke over Chie Arimura of Japan.
Having been three behind leaving the 10th green, Web was home in 33 to add a 69 to earlier scores of 70, 66 and 70. She had a 13-under total of 275 at the par-72 course.
Arimura, who had led much of the tournament, finished the second, and Tseng finished third.
It was Webb's 37th tournament victory on the LPGA Tour but first since March 2009.
"It feels great," she said. "It was a bit of an up-and-down day so I feel very happy to be slinking away with a one shot win."
"Chie," she said, "handled herself really well and was in with a chance all the way. I know she's won in Japan but today would have been a different feeling. She really toughed it out."
"I am just glad that I finished one shot ahead," Webb said.
