2. Mookie Betts, Red Sox
A virtual unknown headed into the 2013 season, Betts has skyrocketed through the ranks of the minor leagues since then. He slashed .309/.411/.491 with 16 home runs and 46 steals between Single-A Greenville and High-A Salem in 2013 and then was even better last year, hitting .346/.431/.529 between Double-A Portland and Triple-A Pawtucket before a summer promotion to Boston. With the Red Sox, he was one of few bright spots on a Boston team which struggled down the stretch, hitting .291/.368/.444 across 52 games. As an athletic pure hitter who can seemingly do it all, there are high hopes for Betts in 2015, with many expecting him to lock down the leadoff role in a potent Red Sox lineup. As a 22-year old rookie, Betts might fall a bit short on those expectations in his first full season, but there’s no doubt that he has the potential to be a major contributor as soon as this season.
