Ian Stewart homered twice and matched a career high with five RBIs and Aaron Cook beat the St. Louis Cardinals for the first time in the Colorado Rockies' 10-1 victory on Saturday night.
Stewart has four homers and 12 RBIs the last five games, including all three three-run homers in the last four games. He hit a three-run shot to right on a full count in the fourth and a two-run shot to left-center on a 2-0 pitch in the sixth, both off Todd Wellemeyer (5-6).
A 10-for-17 surge with four straight multihit games has raised Stewart's average to .231, and he leads the Rockies with 11 homers.
Cook (4-3) allowed a run on four hits in eight dominant innings, facing no batters with runners in scoring position.
