Jonathan Byrd came into Round 4 of the 2011 Wells Fargo Championship with a 2-stroke lead, which he's increased to 3 through seven holes. The leaderboard's front-runner scored birdies on holes No. 6 and 7, extending his advantage over Bill Haas, Brian Davis and Lucas Glover. The former two have just started their back nines, while Glover has completed eight.
Phil Mickelson is nearly done with his day, but has put together an excellent round through 15 holes to enter the top 10 at 11-under. He's posted six birdies to present a 4-under round thus far. Padraig Harrington has had the hottest Sunday, however, shooting 6-under through 15 holes.
If Byrd hangs on, this will be his sixth career tournament win, his second of 2011 and third since October of last year.
