Shi Hyun Ahn kept South Korean players to the fore on the LPGA Tour with the halfway lead at the Wegmans LPGA in Rochester, New York.

Ahn is leading the charge to make it four wins in a row for Koreans on the LPGA Tour.

She shot a 71 to lead compatriot Seon Hwa Lee and American Brittany Lang by one shot.

England's Johanna Head was the only British player to make the cut with a 71 for a two-round total of two over.

Ahn followed up her flawless opening round with a more mixed card with four birdies and three bogeys.

"I think I'd play better if I was a little nervous, but right now I'm not really that nervous," admitted the 21-year-old.

Lee, who has finished three times this year, holed a 12-foot birdie putt on the last hole to boost her chances while Lang also had a mixed day with five birdies and four bogeys.
