21-year old righty reliever Miguel Castro has made the Colorado Rockies‘ Opening Day bullpen. Castro came into this season as the Rockies’ #12 prospect according to Baseball America. He was a key part of the return the Rockies got in the Troy Tulowitzki deal last year. Castro has pitched in 7 games (0 starts) so far in spring training and he is 0-0 with a 3.86 ERA and a 0.86 WHIP. Castro pitched in 18 games (0 starts) for the Jays and Rockies last year in his first taste of the majors and he was 0-3 with 4 saves, a 6.11 ERA and a 1.76 WHIP. Castro also pitched in 27 games (5 starts) in A+AAA-ball last year in which he was 3-3 with a 2.82 ERA and a 1.36 WHIP. The Rockies will never say this, but their is a lot of pressure on Castro to succeed with them because of who they gave up to get him.
