KIAWAH ISLAND, S.C., Aug. 12 (UPI) -- Rory McIlroy
fired a 6-under 66 Sunday, setting a record for the biggest margin of victory at the PGA Championship with an 8-stroke triumph.
McIlroy collected his second major title with the win, which earned him the world No. 1 ranking.
His total of 13-under 275 was eight better than runner-up David Lynn, who shot a 68 to finish at minus-5. McIlroy's margin broke the old mark for one-sided wins at the PGA Championship -- a 7-shot triumph turned in by Jack Nicklaus in 1980.
Tied for third at 4-under 284 were defending champion Keegan Bradley (68), Justin Rose (66), Ian Poulter (69) and Carl Pettersson (72).
Second round co-leader Tiger Woods fell into an 11th-place tie at minus-2 with an even-par 72 in the final round.
