Marc Leishman
Odds: 66/1
The last three winners of the Masters had won at least one tournament previously that year, so Leishman getting a victory at the Arnold Palmer Invitational a couple weeks ago was big for his outlook. Not only that, but he has been remarkably consistent this season (seven Top-25's in nine events), he has the putting game needed to win (second in strokes gained), he loves Augusta, and he has contended here before, finishing fourth in 2013. That's a really good profile for 66-to-1. (Getty)
