Fellow South Korean Inbee Park shot a 66, Christina Kim had a 67 and Alena Sharp a 68 to share second place at 9-under 133.
 
Angry at herself after missing the cut last week, Choi discarded her putter and got a new one. As a result, she’s needed just 53 putts in 36 holes while getting to 11-under 131. She doubled her first-round lead.Golf Irons
 
“I had confidence out there with my friend Inbee Park,” she said. “We enjoyed it. No bogeys today, so I feel perfect.”
 
They’ll also play together for the third straight day in the final pairing on Saturday.
