Wilson flounders to open door for Swede Pettersson
Overnight leader Wilson came into the last day with a four-stroke lead after three successive 65s had taken him to 15 under par, but a damaging 72 over the final round opened the door for Swede Pettersson to take the title by one stroke at 14 under.
Pettersson's three-under 67 was a world away from his tournament-record ten-under-par 60 on the third round, a score which hauled him from the brink of the cut to a share of second place overnight but was sufficient to secure him his fourth PGA Tour victory.
