3. Rory McIlroy
Odds: 15/2
Best Masters Finish: 4 (2015)
It's been a fairly quiet season for McIlroy, who missed nearly two months earlier this year with a significant rib injury. However, that's less of a concern considering how he's looked since his return, finishing seventh at the WGC-Mexico and fourth at the Arnold Palmer Invitational.
As always, the World No. 2's tee-to-green game is unmatched, with the exception of maybe DJ. But whether or not Rory--who has finished Top-10 here in three straight years--is able to finish off the career Grand Slam will come down to how he fares with the flatstick. (Getty)
