22. Ryan SweeneyPrevious ranking: 20
A good defensive outfielder who came over from the A's in the Andrew Bailey/Josh Reddick deal, Sweeney has had his moments for the Sox -- he's hitting .292. But he's yet to homer in 183 plate appearances and is currently on the disabled list. With Jacoby Ellsbury and Carl Crawford eventually returning, Daniel Nava thriving and Ryan Kalish finally healthy, his role may be limited.
