The Rockies will take on the Diamondbacks at Salt River Fields.
The Rockies have made their first cuts to the roster. The next few weeks of play will continue to reveal the 2013 roster. As ever, the starting rotation is still a huge question mark. Today we will see Tyler Chatwood continue his bid for a starting rotation spot. Chacin will also pitch, albeit in a simulated game, as he returns to the team after Venezuela's elimination from the WBC.
