Colorado Rockies: Ranking the 40-Man Roster: 26-30

Number 27

Miguel Castro: Relief Pitcher Points: 156 Highest Rank: 22 Lowest Rank: 32

Miguel Castro faced some lofty expectations in his first year with the Rockies, but after being included in one of the biggest trades in franchise history, it was to be expected. Castro is a hard-throwing right-handed reliever with a fastball that can reach triple digits. He has only been used as a reliever in his young career, but there was some bit of expectation he would move to the rotation after developing a solid offspeed pitch.

At just 22 years old, Castro has plenty of time to develop in to the superstar the Rockies were expecting when they shipped out Troy Tulowitzki. He spent a good bit of time in the minors in 2015, where he worked an impressive 2.82 ERA over 27 games, including a 1.32 ERA with AAA Albuquerque. After breaking in to the majors again in 2016, he suffered an injury and was limited to just 19 games.

The 2017 bullpen for the Rockies will look very different from 2016, and Castro has the chance to prove himself again this spring. If he does not do enough to break camp with the Rockies, they could begin his transition to starter if they see fit. He could also work as the primary closer in AAA, which was a role he held for the Blue Jays before being traded.

Whether Miguel Castro becomes a rotational piece for the Rockies, or a solid late-inning flamethrower, his long term promise is greater than the impact he will make in 2017. It will be interesting to see how his ranking changes next season as well.
