Headlining the list in terms of career resume is 41 year old pitcher Miguel Batista, signed to a minor league contract this offseason. The right-hander has worked regularly in both a starting and relief role throughout a twenty-plus year major league career. He has pitched at the major league level with 13 different teams and has reached the level every year since 1996. His streak may be broken this year, as unless there is an unexpected opening for a bullpen hybrid role, there is no clear path to the majors for Batista. As he filed for MLB free agency last year, Batista will cost the Rockies an extra $100k if he pitches in the minors, making him a likely release candidate if no roster spot is available.

Chris Volstad is another name new to the Rockies this season, signed after being cut from the Chicago Cubs after a very rough 2012. The former Marlins prospect was likely a personal pickup on behalf of Mark Wiley, the Rockies new Director of Pitching Operations, who worked with the Marlins during Volstad's ascension to the majors. He represents the most likely NRI to crack the opening day roster, as he will be competing for a starting rotation spot with the likes of Christian Friedrich, Tyler Chatwood and Drew Pomeranz, all of whom can easily be stashed in the minors if needed.
