SCOTTSDALE, Ariz. (AP) -- Mark Wilson charged and Camilo Villegas faltered.
The result was a two-way tie for the lead at 11-under 131 halfway through the Phoenix Open.
Wilson birdied the last four holes for a 5-under 66, while Villegas bogeyed No. 18 when he missed a 14-foot putt for par. The 28-year-old Colombian settled for a 69 after tying the tournament first-round record with a 9-under 62 on Thursday.
Eleven players were within two shots of the lead at TPC Scottsdale, where a crowd estimated at 101,709 attended the second round Friday under thinly overcast conditions.
Anthony Kim (65), Ryan Moore (66) and Rickie Fowler (67) were 10 under.
Tom Lehman, nine days shy of his 51st birthday, had a 67 to top a group of six at 9 under. Play was suspended because of darkness with one player, Matt Every, still on the course. He had a 3-footer for a birdie that would put him at 9 under.
Wilson, who said he was ill early in the week after returning from the Mayakoba Golf Classic in Cancun, Mexico, considers himself the bland one among those at the top of the leaderboard.
