The Colorado Rockies’ two most important starting pitchers both took the mound in the Rockies’ 4-2 Cactus League loss to the Chicago Cubs yesterday. Jhoulys Chacin worked two hitless, scoreless innings to start the game. Jorge de la Rosa scuffled a bit in relief, allowing two runs on two hits and a walk in his two innings. Carlos Gonzalez had two hits to lead the Rockies offensively. The Rockies face a San Diego Padres split-squad this afternoon.
