South Korea`s Meena Lee fired 10 birdies in a seven-under par 64 second round Friday to grab a share of the lead at the $1.3 million LPGA North Texas Shootout.
Lee and Germany`s Caroline Masson, who fired her second consecutive 67, topped the leaderboard on eight-under 134 after 36 holes at Las Colinas Country Club.
"I had confidence with my putting, so I made a lot of birdies," Lee said. "I`m playing well and the course is really good. Good green speeds."
Americans Stacy Lewis and Natalie Gulbis shared third on 135 with compatriot Christina Kim another stroke adrift.
Norway`s Suzann Pettersen, Paraguay`s Julieta Granada, Dutchwoman Dewi Claire Schreefel and Americans Dori Carter and Cristie Kerr were next on 137.
Lee opened on the back nine with an eagle at the par-5 10th. After a bogey at 11, she fired back-to-back birdies before another befell her at 14.
She followed that with three birdies in a row before taking a bogey at 18, completing nine holes in four-under 31 without a single par.
"I made eagle, so started very good, and then my putting was really good," Lee said. "Inside 15 feet for par, almost always made it.
"I had a lot of birdies. My irons were inside 15 feet almost every hole. Everything was on my side on the first nine."
Lee played her second nine without a bogey but ran off another birdie streak at the par-5 third, par-3 fourth and par-4 fifth, then parred the last four holes to claim her share of the lead.
Masson had less of a roller coaster round, with back-to-back birdies at the second and third and to open the back nine.
"I started off well again, made some birdies, maybe didn`t play as good as yesterday, but I made some good putts and I played pretty consistent," said Masson.
"I`m just trying to enjoy it, have fun, not try to have any pressure get to me, just having a good time."
Masson made her lone bogey at the eighth and closed with a birdie at the par-5 18th.
"I finished with a birdie, so overall, yeah, I think it`s a great day. I just have to keep doing what I`m doing, stay patient. Everything is good," she said.
"I just feel comfortable with my game. It feels like I`m hitting it solid. I don`t really mis-hit many shots so that makes me feel pretty confident out there."
