A look back at the first three rounds of the Wells Fargo Championship at Quail Hollow Club:
Charlotte native Bill Haas' bogey-free 64 is good enough for Thursday's first-round lead. Haas finishes two strokes better than David Toms and former Clemson golfer Jonathan Byrd and ties for the lowest first-day score at Quail Hollow (Kirk Triplett, 2004). Toms has an eagle on the par-5 seventh and Byrd only has to deal with one bogey.
Pat Perez shoots a 65 and takes a two-stroke lead over Haas and Byrd by the end of the day. Perez's 12-under-par 132 breaks the tournament record for the lowest 36-hole score. First-round leader Haas shoots a 70 to stay close. Perez has 18 birdies over the first two rounds.
Byrd goes to 15 under par for the tournament and takes the lead from Perez, who is one stroke back. Stewart Cink and Lucas Glover are also hovering three strokes behind at 12 under. Byrd is hot from holes seven through 15, with birdies on seven of them as he takes a lead into the final day for the first time in his career.
