Preston Claiborne

Claiborne was shuttled between Triple-A and the big leagues last season, struggling with free passes at both levels and doing little to establish himself in the bid for an Opening Day roster spot. Working with a low-90s fastball, slider, and changeup, Claiborne needs to utilize his secondaries effectively in order to retire big league hitters consistently. His numbers in 2014 likely took a hit because of lost velocity on his fastball, as his average fastball slipped from 93.1 mph in 2013 to 91.0 last season. In his final season with minor league options remaining, he'll likely shuttle between Triple-A and the big leagues. Even if things begin to click again, his ceiling may be that of a middle reliever. After being claimed off waivers by the Marlins during the offseason, Claiborne will try to reach that level in Miami.

Claiborne was a pleasant surprise in the Yankees bullpen throughout much of 2013, but he wore down later on in the season, giving up 14 earned runs in his last 12.1 innings. Claiborne doesn't have a single standout offering, but has pretty good command of all his pitches, and could stick with the Yankees as a middle reliever, albeit one without a ton of upside.
