Chris Capuano's scintillating start with the Los Angeles Dodgers has provided quite a boost for a rotation that needed some depth, an ingredient that was sorely missing last season. Capuano won his fourth straight outing, and the Dodgers got home runs from Andre Ethier, Mark Ellis and Juan Uribe to beat the Colorado Rockies 7-3 on Friday night and open a six-game lead in the National League West over San Francisco.
