South Korea's Lee Mi-hyang is trying to keep her nerves in check after taking the halfway lead at the Evian Championship in France.

Lee, 22, is one shot ahead of American Morgan Pressel on nine-under-par in the fifth major after a second-round 67.

"I don't want to think about the score. It is a little nervous for me," said Lee, who has won only three events.

Pressel recorded a 65, the best round of the day, with Nicole Broch Larsen a shot back on seven under after a 67.

England's Charley Hull was in a tie for 15th on two under, one shot ahead of world number one Inbee Park.
