My, how things have changed at St. George's. Carl Pettersson rolled in a 15-footer on the par-4 14th for his fifth birdie of the day, putting him at 14 under as he guns for his first win since the 2008 Wyndham Championship.
Dean Wilson, on the other hand, encountered a messy 14th. He missed the green despite a perfect drive and failed to get up and down.
Pettersson now has the lead by himself for the first time since the third round, when he led by one after his early-morning 60.
