absolutely wide open this year, with many of the big hitters either out or below par (which i know is good in golf, but in this sentence, it's not).
As ever with Augusta it's basically the guy with the best short game and putting over the weekend who wins. This always means Mickelson is in with a shout if he's shooting well, as well as non-Major winners Garcia and Donald. Cabrera always seems to raise his game for this as well, and is always worth a shout.
For me, I'm going to go with Justin Rose. Out of the spotlight, really, but his US Open win on that daft course shows he's got the mettle, even on the toughest rounds of 18. If he can put well then he'll certainly be up there.
