Rory McIlroy pulled away from all challengers on Sunday with a final round 66, winning the 2012 PGA Championship and claiming the top spot in the world golf rankings in the process.
McIlroy finished the tournament at 13-under, eight strokes ahead of second place finisher David Lynn. Sweden's Carl Pettersson, who led the tournament after the first round and was tied for the lead after the second round, finished in a four-way tie for third place at four-under.
Tiger Woods was in contention after the first two rounds, but could not maintain his good play through the weekend, a recurring problem in majors for Woods in 2012. Woods finished 11 strokes behind McIlroy, in a group with Graeme McDowell and Bubba Watson, among others, at two-under.
