Jorge Rondon

After finally getting a taste of MLB (albeit just one inning), the 26-year-old Rondon was placed on waivers by the Cardinals following the season and promptly claimed by the Rockies. The hard-throwing righty has fared reasonably well the last two seasons at Triple-A but has struggled with his command at times. He managed to lower his walk rate significantly in 2014, which should offer the Rockies some hope that he can contribute out of their bullpen this year. It's possible with a strong spring that he could break camp with the team and even pitch meaningful innings for them. The Rockies' bullpen is as good a place as any for Rondon to try and make an impact at the MLB level.
