Rory McIlroy has got the Americans running scared. The US Ryder Cup captain, Tom Watson, said it all: "I wish he was on my team." The deference, respect and indeed fear engendered by the name Rory McIlory is a thing to behold. It is not just that he wins, but how he wins that is reshaping golf's parameters.
The US PGA Championship victory at Valhalla was his second major triumph in a month, and the most dramatic of the four he has tabled at the age of 25. Snaps of him holding the Wanamaker Trophy and the Claret Jug in the Valhalla club house captured the dawn of the post-Tiger era.
As Watson observed, McIlroy knows it, and so do his rivals. With nine holes to play McIlroy was in new territory, three shots adrift. His three previous major wins came on the back of huge 54-hole leads. Here he needed to reel in three players going away from the field, Phil Mickelson, Rickie Fowler and Henrik Stenson, and he did, with a shot to spare.
"Satisfaction and joy are the two biggest things," McIlroy said after his victory. "Satisfaction I was able to win and the manner I won, and joy that I have been able to keep this run of form going. I said at The Open that I wanted to keep moving forward, I didn't want that to be the end of the season for me, I wanted to win more. I was able to back that victory up with a win at the Bridgestone Invitational and to come here to Valhalla and do it all over again.
"To win the way that I did, I know I can do it now. I was standing on the 10th fairway three behind and to know I can come back from that and shoot 32 on the back nine of a major and win is something that will stand with me for the rest of my career."
