Stewart’s power, Cook’s pitching lead Rockies to 10-1 win over Cardinals

Stewart, Cook lead Rockies past Cardinals 10-1

ST. LOUIS — 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. Two of his three multihomer games have come this season, the other against the Astros at home on May 12, and 14 of his last 20 hits have been for extra bases. He also doubled Saturday night.

Cook (4-3) allowed a run on four hits in eight dominant innings, facing no batters with runners in scoring position. He lowered his career ERA against St. Louis to a still hefty 5.61, with the only damage coming on Rick Ankiel’s third homer in the sixth. Cook had been 0-4 against St. Louis.

Clint Barmes added a three-run homer in the ninth off Blake Hawksworth, making his major league debut. The Rockies are 5-4 under manager Jim Tracy after going 18-28 under Clint Hurdle.

The Rockies have reached double-digit runs three straight road games for the first time since April 7-9, 2006 at San Diego, totaling 31 runs after a four-game losing streak in which they scored nine runs. They’ve also beaten the Cardinals four straight times.

The Cardinals had four hits and have lost six of nine, scoring three or fewer runs six times during that span including one victory.

Wellemeyer made it through seven innings despite his troubles with the long ball, allowing only four other hits with six strikeouts. All three of his walks produced runs for Colorado.

Wellemeyer lost for the first time in four career decisions against the Rockies, and also fell to 2-5 with a 5.72 ERA at home this season. He’s 3-1 with a 4.56 ERA on the road.

Seth Smith drew a leadoff walk, went to third on Barmes’ single and scored on Todd Helton’s sacrifice fly to give the Rockies the lead in the first. Wellemeyer walked Helton and Garrett Atkins with one out in the fourth and Stewart hit his 10th homer of the year with two outs on a full count to give Cook a 4-0 cushion.

Stewart hit a two-run shot in the sixth to make it 6-1.
