Ben Curtis will enter this weekend at TPC San Antonio with an excellent chance to win his first PGA TOUR event in six years. Curtis, taking advantage of an early tee time, shot his second consecutive 5-under 67 on Friday at the Valero Texas Open and went into the weekend at 10 under. Curtis leads David Mathis by two strokes. The 2003 British Open champion, whose last TOUR win came at the 2006 84 LUMBER Classic, has not suffered a bogey through his first 36 holes -- the fourth player this year to go bogey-free through 36 holes of a TOUR event. The players who teed off in Friday morning got the big advantage in terms of weather, as they managed to get most or all of their rounds in before stiff winds and rainy conditions kicked in. Play was stopped for nearly two hours in the afternoon, which means the second round will not be completed until Saturday morning. Nearly two dozen players will return to TPC San Antonio at 7:30 a.m. local time Saturday morning for the completion of Round 2. Mathis also shot 67 in the morning wave and finished at 8 under. First-round leader Matt Every is 2 over through 16 holes in the second round and is tied for third.
