Mixed fortunes for Maguire and Mehaffey as Lee sees her lead cut
Mirim Lee saw her advantage atop the Ricoh British Women's Open slashed to a single shot, despite carding a one-under-par 71 in her second round at Woburn.
The South Korean followed up her opening 62 - which equalled the lowest round in the competition's history - with three birdies and two bogeys yesterday.
That moved Lee to 11 under par overall, a score good enough for the outright lead at the halfway stage, but China's Shanshan Feng and Thailand's Ariya Jutanugarn are breathing down her neck.
Lee said: "I felt a little bit of nervousness, but after a couple of holes I forgot about it. I think a little bit of nervousness is what makes you play well."
The World No.31 made a tentative start, but settled into her stride with birdies on the fourth and seventh. She added another on the 15th, but bogeys at the 13th and 17th holes dropped her back.
Jutanugarn was the closest challenger to Lee overnight and cut the deficit with a round of 69, while Feng sits alongside her on 10 under par overall.
Cavan's Leona Maguire, meanwhile, made the cut with ease after a two-under-par 70 yesterday.
That puts the 21-year-old on three under for the tournament, eight shots behind Lee.
Royal County Down's Olivia Mehaffey, however, missed the cut.
She carded a second-round 74 to finish on five over overall, four shots off the cut mark.
