WONJU, South Korea -- Andrea Lee shot another bogey-free round of 6-under 66 to take a two-stroke lead at the BMW Ladies Championship on Friday.
Lee had two birdies on the front nine of the second round before wrapping up another impressive day with back-to-back birdies on the last two holes for 12-under 132 overall.
"Another bogey-free round which I'm really pleased with," Lee said. "Hit all the greens, all the fairways and just made some putts out there. ... Hopefully I can keep it going this weekend."
Overnight leader Atthaya Thitikul (71), Lilia Vu (66) and 16-year-old amateur Minsol Kim (70) shared a three-way tie for second place.
Thitikul, who set a tournament record of 9-under 63 on the opening day, slipped after bogey-double bogey at Nos. 12 and 13. She made sure she remained in contention with a birdie on the 14th and an eagle on the par-5 15th.
"It's been like a roller coaster back nine," Thitikul said.
