Playing well, and at these odds, a good bet:
GRAHAM DeLAET 50/1
I think Rory and Spieth are popular picks, but Rory probably has a much better chance because he's playing well, and has been close before.
Personally, I'd like to see Phil win a fourth jacket, and then top it off with a US Open win.
Yes, that is a good bet at 50 to 1.
