Brittany Lincicome and Kelly Tan are tied atop the Women's PGA Championship leaderboard following the opening round.
Lincicome and Tan both carded 67s to earn a share of the one-stroke lead at Aronimink Golf Club in Pennsylvania on Thursday.
After missing the cut at last week's LPGA Classic, two-time ANA Inspiration champion and eight-time LPGA Tour winner Lincicome bounced back in windy conditions by birdieing four holes and only dropping one shot.
"I've had so much time off since having [daughter] Emery and taking time off and COVID," she said. "Each week it's just kind of been let's make the cut, let's make the cut, and that's not a way an eight-time winner should play golf."
Cydney Clanton, Danielle Kang, Lydia Ko, Linnea Strom, Carlota Ciganda and Gaby Lopez are a stroke off the pace.
Meanwhile, defending champion Hannah Green struggled after posting a nine-under-par 79 to leave her bid for back-to-back titles in tatters.
