Rory McIlroy has won his first two majors by a combined 16 shots (8/2011 U.S. Open and 8/2012 PGA Championship). It compares very favorably to Tiger Woods, who won his first two majors by a combined 13 shots (12/1997 Masters and 1/1999 PGA Championship). With the win, McIlroy joins Woods as the only two active players under age 40 with multiple major wins. The Northern Irishman collected his second win in 17th start in a major. Tiger Woods won his second in his 18th (12/pro and 6/amateur) start in a major. McIlroy (23 years, 3 months, 8 days) is the youngest player to win the PGA Championship since Tiger Woods (23 years 7 months, 15 days) in 1999. For anyone wondering, Gene Sarazen is the youngest winner of the PGA Championship (1922) at 20 years, 5 months 22 days.
Rory McIlroy ended a streak of four consecutive come-from-behind wins in the majors. Keegan Bradley won last years PGA Championship coming from behind and the first three majors in 2012 were also won by players coming from behind to win (Bubba Watson by 3 at the Masters, Webb Simpson by 4 at the U.S. Open and Ernie Els by 6 at the British Open. He was bogey-free in the final round to win and the last player to do that in a major championship and win was Phil Mickelson (2010 Masters).
Rory McIlroy finished the PGA Championship making 45 pars, 20 birdies and 7 bogeys. He opened the championship going 22 consecutive holes without a bogey and finished the 23 consecutive holes without a dropped shot. He was the only player in the field to shoot three rounds in the 60's but his second round may have been the difference maker for him. The scoring average was 78.10 for the second round and it is the highest for any single round in PGA Championship history. McIlroy shot 75 but it could have been even higher he said. “I was 4‑over through 13 holes on Friday. It had all the signs of a round that could get away from you,” he said. “I dug deep and made that birdie on 14, and a silly bogey on 15, but to come back and play 16 well and birdie that, and par the last two, that was definitely a line that I held together well and that 75 could easily have been a 77 or 78. I definitely feel like I'm getting better at handling conditions and being able to just know when a 74, 75 is a decent score and move on and know that the next day should be a bit better.”
Tiger Woods has yet to come-from-behind to win a major championship. He was five back to start the final round on Sunday. McIlroy has lead going into Sunday each of his two major championships.
