The 2012 PGA Championship was the 94th PGA Championship, played August 9–12 at the Ocean Course of the Kiawah Island Golf Resort in Kiawah Island, South Carolina, southwest of Charleston. Rory McIlroy shot a bogey-free 66 (−6) in the final round to win his second major title by eight strokes over runner-up David Lynn.
The second place finisher lost by eight strokes. 
McIlroy won the tournament by 8 strokes, which means that the second place finisher lost by that many. He would have had to have played 9 strokes better to have won. It may have been difficult for the system because it required recognizing a secondary subject (the second place finisher) and the concept of losing by a certain amount of strokes.
