Outfielder and part-time first baseman Tyler Colvin arrived at spring training riding the wave of his breakout 2012 season.

The ride ended Friday when the Rockies optioned Colvin to the Triple-A Colorado Springs Sky Sox. The move opened the door for infielders Reid Brignac and Jonathan Herrera to make the 25-man roster.

While spring training statistics don't always mean a lot, in Colvin's case the numbers mattered. He hit only .167 with a team-high 14 strikeouts. Colvin spent the entire 2012 season with the Rockies, batting .290 with 27 doubles, 10 triples, 18 home runs and 72 RBIs in 136 games.

Sending Colvin down can also be viewed as a way to get Jordan Pacheco more playing time at first base behind aging starter Todd Helton. Colvin's demotion also could be temporary, with the Rockies hoping he breaks out of his slump while playing at Triple-A.

The move leaves the Rockies stocked with infielders, but with just four outfielders: Carlos Gonzalez, Dexter Fowler, Michael Cuddyer and Eric Young Jr.
