Pittsford, NY (Sports Network) - Eun-Hee Ji fired a three-under 69 on Saturday to take a one-shot lead over Karrie Webb after three rounds of the LPGA Championship, the tour's second major of the season.

Ji moved to four-under par 212 during a day when rain delayed play at Locust Hill Country Club for more than two hours.

But Ji managed a very good score and will carry a slight advantage into the final round, when she will try for her second major title. The 26-year-old won the U.S. Women's Open in 2009.

Webb, a seven-time major champion and 2001 LPGA Championship winner, shot a four-under 68 to move into second place at minus-three.

World No. 3 Stacy Lewis climbed into contention with a two-under 70. The American has already taken two victories this year to add to her title at last year's Kraft Nabisco victory.

Lewis sits at two-under 214 and shares third with world No. 5 Suzann Pettersen (71), Inbee Park (72) and first-round co-leader Giulia Sergas. The Italian Sergas fell behind thanks to a 76 on Friday, but rebounded with a third-round 69.

Second-round leader Se Ri Pak, playing for the first time since she dislocated her shoulder in early April, struggled on Saturday. The Hall of Famer carded a four-over 76 and tumbled down the leaderboard into a share of 15th, at plus- one.
