The Colorado Rockies created another option at shortstop and a way to beef up their offense when Ian Desmond returned to the position Monday. After the Rockies beat the San Francisco Giants 4-3 on Carlos Gonzalez's walk-off walk with two outs in the ninth inning Monday, Rockies manager Bud Black was asked if Desmond would start at shortstop Tuesday when Colorado's Tyler Chatwood (6-12, 5.00 ERA) starts against Giants left-hander Ty Blach (8-11, 4.68).
