In addition to holding Drew Pomeranz off the roster until he's needed on April 15, the Rockies will also hold Jamie Moyer off the opening day roster but will activate him prior to Saturday's game in Houston. That affords Jim Tracy some position player depth in case the opener goes extras and even if Troy Tulowitzki's elbow is still barking.
Most surprising name on the roster: Tyler Chatwood
I didn't see this coming, but it actually makes sense to have Chatwood around early in the season when the starters may not go as deep into the game. He's the type of guy that can give 2-3 innings at a moment's notice, so that's a nice option for Jim Tracy. That said, he'll probably be the pitcher that goes down once Moyer and Pomeranz come up and the roster is set because he needs the most seasoning and doesn't project as a reliever.
Most surprising name missing: Edgmer Escalona
The only thing Escalona had going against him this spring was the option remaining on his contract. Well, that, and a rough outing today that included beaning Jesus Montero (awful timing). Yeah, overall it was a tough day for Edgmer, but he'll be back in the big leagues soon enough you can bet on that.
