Williamsburg, Va. ? Billy Mayfair didn’t have a 5 on his scorecard in a bogey-free, 8-under 63 Friday and grabbed a share of the second-round lead in the Michelob Championship with up-and-down David Duval.

Duval shot a 69, but he started with two bogeys and added two more to get to 9-under 133. First-round co-leader Hidemichi Tanaka also struggled and was one shot back.

Loren Roberts, Corey Pavin and Charles Howell III were among a group of six at 135. Roberts shot a bogey-free 69 that ended with 11 consecutive pars, Pavin had a three-bogey 69 and Howell had seven birdies in a 65.

With a slight breeze blowing in off the James River in the afternoon, Duval’s errant driving often left him in the thick, gnarly rough that compares to that found at a major championship.
