BARRINGTON, R.I. (AP) -- The pair of Bubba Watson and Camilo Villegas shot a 10-under 61 Monday to grab the first-round lead in the CVS Caremark Classic. The two-day, 36-hole charity team tournament is run under a best-ball format and concludes Tuesday.

Watson-Villegas made the turn leading by one stroke after combining for a 6-under 30 on the front nine. Watson made an eagle on the par-5, 516-yard eighth hole.

Rocco Mediate and his teammate, Brandt Senedker, shot a 9-under 62 to tie for second place in the first round with three other pairs -- Paul Goydos and Tim Herron, Billy Andrade and Davis Love III and Charles Howell with Nick Price.

"We hit the ball well over the first few holes and it took a lot of pressure off," Watson said. "For the most part we hung in there and had chances."

Watson-Villegas birdied each of the first four holes and appeared to be in position to challenge the tournament record of 13-under 58 set in 2001 by the teams of Brad Faxon-Gary Player and Dudley Hart-Herron.

But after making birdie on the 13th, 14th and 15th holes, Watson-Villegas only could make par on each of the last three.

"What really hurt us was that we only made par on the last three holes," Watson said.

Laura Diaz and Nicole Castrale, the second women's team to play in the 10-year tournament, missed tying for the lead when they each missed a par putt on the 18th hole and combined for bogey.

"We got some excitement going in the crowd," Diaz said, "but I felt we left some shots out there."

Brett Quigley combined with his uncle, Champions Tour veteran Dana Quigley, to shoot 8-under 63 and made eagle on the par-5, 538-yard 11th hole by chipping in from three yards off the green.

Brett Quigley incurred a stress fracture in his left leg two weeks before the U.S. Open. Earlier this year he had arthroscopic surgery on his right knee.
