What Rory McIlory is doing here, on his first trip to the PGA Tour, is so impressive. He's 19, from Belfast, and playing in his first stroke-play event on the PGA Tour.

Maybe you're thinking he's thinking: Help me, mummy, this is all so new for me and I can't handle it!

Hardly.

How can a 19-year-old be so seasoned? He opened with a 68, improved by two in the second round, talked to the press and signed autographs like a veteran, and always has a look about like this-is-fun.

He won a junior event as a kid at Doral, no shot scares him. It's hard to imagine that he won't narrow the distance on Saturday between himself and the leader. Unless he becomes the leader himself. I've been watching this kid closely for three weeks now. I've figured out one thing: he ain't no kid. It's not just the shots, which are fantastic; it's how he carries himself.
