Barring someone else lighting it up for 36 holes, I think he'll win. He's very familiar with the course, part of the reason he hit so many putts. He's been playing it since he was a kid.
He seems to have found his stroke, hitting a lot of fairways and greens down the stretch yesterday. If he's found his swing, then he'll pull away from the field over the last 36 holes.
Granted, if I had to put money on it, I'd take the field. I don't care how good he is, he's not good enough to be able to say the odds are in his favor to win over the entire rest of the field.
