The Colorado Rockies picked up their sixth straight victory in Cactus League play with a 7-5 triumph over the Chicago Cubs yesterday afternoon. Catcher Wilin Rosario and utility-man Jordan Pacheco, both vying for roster spots, hit two-run home runs, and starting pitcher Jhoulys Chacin worked three shutout innings. The Rockies take on the Cincinnati Reds in Goodyear, Arizona tonight.
