Aaron Cook pitched a four-hit shutout and Todd Helton's grand slam ended Colorado's power slump as the Rockies beat the Atlanta Braves 9-0 on Thursday night.
Cook (3-1) retired the final 16 batters for his second career shutout. He had 20 groundouts and did not allow a baserunner to advance past second for his first win in eight career starts against Atlanta.
Jeff Francoeur singled with two outs in the fourth and then Cook retired everyone else.
The Rockies had gone four games -- and 46 innings -- with a homer before Helton's shot in the fourth inning. Before that mini-drought, the Rockies had not had as many as two straight games without a homer this season.
