BARRINGTON, R.I. (AP) — Suzann Pettersen and Hunter Mahan (FSY) made up two strokes on the last two holes and tied Juli Inkster and Boo Weekley (FSY) for the lead at 10-under par after the first round of the CVS Caremark Charity Classic on Monday.

The teams shared the lead after opening 61s in the 10-team best-ball tournament involving PGA Tour, LPGA and Champions tour members at Rhode Island Country Club. The 36-hole event concludes Tuesday.

Pettersen and Mahan were 8-under with two holes remaining before the six-time LPGA Tour winner rolled in a 15-foot birdie putt at the 17th and Mahan made a 10-footer for birdie at the 18th to forge a tie.

"Suzann made a great bird on 17 and I had an easier one on 18," Mahan said. "The greens were exceptional. I thought they would be softer but they were in perfect shape.

"It's a great course to play on because you can make some birdies."
