VIENNA, Ohio -- Kelly Robbins - winless in her last 82 tour events - had two eagles in an 8-under-par 64 and she shared the lead with Beth Bader after Friday's rain-delayed opening round of the Giant Eagle LPGA Classic.
Bader hasn't finished higher than a tie for 30th in her two years as a pro.
Robbins holed a bunker shot on the par-5 5th, then hit driver and 3-wood to 4 feet for another eagle at the par-5 8th.
Bader had 10 birdies and two bogeys for the best score of her career.
The 64s were the lowest competitive rounds ever shot at Squaw Creek Country Club.
Lightning and heavy rains delayed play for more than 2 hours, shortly after the leaders finished their rounds.
Two-time defending champion Dorothy Delasin - seeking to become only the eighth player to win the same LPGA tournament three years in a row - shot a 69.
Mi Hyun Kim of South Korea was joined at 65 by Danielle Ammaccapane, while rookies Natalie Gulbis and Jung Yeon Lee each shot a 67.
Ammaccapane, who played most of her round after the suspension of play, had to hit woods to the green on the last four holes because the wet course was playing so much longer.
Robbins, who has won nine tour events but none since 1999, turned the front side in 5-under 32. She added four birdies on the back nine - twice hitting wedge shots that ended up 2 feet from the pin - to move into a tie with the unheralded Bader.
Robbins won at least one LPGA event for seven straight years, including the initial tournament of 1999, the HealthSouth Inaugural.
She has gotten at least a share of second in three tournaments since, but has not won in 82 previous starts, including 12 this year.
Shortly after Robbins concluded her round - with about half the field still on the course - play was suspended as lightning and thunder rocked the course. Heavy rains saturated the greens and turned the bunkers into small ponds.
Playing in one of the first groups off the 10th tee, Bader birdied the first three holes and didn't let up. She added three more birdies and a bogey in a back-nine 30, then birdied three of the last four holes on the front side to beat her previous career-low score by two strokes.
Seven of Bader's 10 birdie putts were shorter than 10 feet.
Bader shot a 66 in the second round of the Corning in May to share the lead with Laura Diaz and Sherri Steinhauer, but then came back the next day with a 77. She finished in a tie for 65th, 17 shots behind Diaz.
Nancy Lopez, making her farewell trip around the LPGA Tour, had a 74.
