Troy Tulowitzki drove in two runs and Jorge de la Rosa threw four shutout innings as the Colorado Rockies blanked the Chicago Cubs 2-0 in Cactus League play. De la Rosa struck out six Cubs and twice escaped bases-loaded jams in his most encouraging outing of the spring. Tulowitzki had an RBI double in the first inning and added a sacrifice fly in the sixth. The Rockies are off today.
