VIENNA, Ohio (Ticker) -- Kelly Robbins tied the course record with an 8-under-par 64 Friday and has a share of the lead entering Saturday's second round of the Giant Eagle LPGA Classic.

Looking to end a victory drought of more than 3 1/2 years, Robbins made two eagles, six birdies and two bogeys at the Squaw Creek Country Club before thunderstorms and threatening weather delayed play for 2 hours, 16 minutes.

Robbins, who has nine wins in an 11-year career, is tied with Bader, who is winless in her second year on the LPGA Tour. But Bader enjoyed the best round of her brief career, burning Squaw Creek for 10 birdies and two bogeys -- all while playing the four par-5s at 1-over.

Danielle Ammaccapane and Korea's Mi Hyun Kim are tied for second after opening-round 65s. It's another two strokes back to 19-year-old Natalie Gulbis and Korean rookie Jung Yeon Lee.

Dorothy Delasin started her quest for an historic "three-peat" with a 3-under 69.

The 21-year-old Californian is trying to become the eighth player in LPGA Tour history to post three consecutive wins at the same event. The list includes Britain's Laura Davies, who won the Standard Register PING each year from 1994-97; Sweden's Annika Sorenstam; and Australia's Karrie Webb.

While Bader struggled on the par-5s, Robbins thrived, making eagles at the 479-yard fifth hole and the 486-yard eighth.

It's also been a while since her last win, which came at the season-opening Healthsouth Inaugural in 1999. Before that, she was one of the most promising American players, combining for four wins in 1997 and 1998.

A bogey at the par-4 sixth hole was sandwiched between the eagles, but Robbins played the back nine at 3-under, making birdie putts of 10 and 15 feet at the 16th and 17th holes, respectively.

Bader does not have nearly as much experience to draw upon as she seeks her first career top-25 finish.

It worked. Starting on the back nine, Bader birdied six of her first nine holes around a bogey at No. 13. She had four more birdies and another bogey on the front side, rolling in a five-foot putt at the 134-yard ninth hole to join Robbins at 8-under.

This 54-hole tournament is the final American-based qualifier for the Women's British Open, the last major of the season. The top five scores from eligible players through the first two rounds will earn spots in the field for the event that begins August 8 in Scotland.

Last year, Natascha Fink, Suzanne Strudwick, LaRee Sugg, Australia's Shani Waugh and France's Marie-Josee Rouleau qualified at this stop.

Squaw Creek is a par-72, 6,454-yard layout. The $1 million purse features a $150,000 first prize.
