Matt Carpenter led off the game with a double to right.
It was the start of a double feature - a big day for him and another big series win for the Cardinals.
Carpenter tied a St. Louis record with four doubles, pitcher Austin Gomber had a two-run infield single in a six-run first inning and the Cardinals routed the Colorado Rockies 12-3 on Sunday.
Carpenter matched a franchise mark that Joe ''Ducky'' Medwick set on Aug. 4, 1937, against the Boston Bees (now Braves). Carpenter doubled twice in the first, had another in the third and lined his fourth in the seventh on a day when St. Louis pounded out 16 hits. The first baseman wound up 4 for 5 with two RBIs.
The Cardinals took two of three from the Rockies in a series between NL playoff contenders. It was the ninth straight series St. Louis has captured.
The score was 6-0 before many of the fans even had time to settle into their seats. The Cardinals sent 11 batters to the plate in a wild first and had seven hits off Tyler Anderson, including a two-run homer by Tyler O'Neill. Anderson later intentionally walked Yairo Munoz to get to Gomber, who bounced a high hopper for an infield hit. A hustling Harrison Bader scored from second.
The runs in the first were scored with two outs.
Wearing ''Big G'' on the back of his uniform as part of Players' Weekend, Gomber (4-0) threw six efficient innings and allowed two runs, one earned, to become the first left-handed Cardinals starter to win at Coors Field since Kent Mercker on July 24, 1999.
Despite St. Louis leading 10-2 after three innings, the crowd predominantly stayed around. This provided a big incentive: A screening of ''The Sandlot'' at the ballpark following the game.
Anderson (6-7) was booed as he walked off the mound after allowing six runs and getting just two outs. He was replaced by Chad Bettis.
The left-hander has been tinkering with a new release point to better utilize his 6-foot-3 frame. He hasn't won since July 4, and has a 15.09 ERA over his last three outings.
Up next for the Cardiansl, RHP Jack Flaherty (7-6, 2.97 ERA) takes the mound Tuesday when the Cardinals open a three-game series against Pittsburgh. Flaherty needs six strikeouts to reach 150 and tie Paul Dean (1934) for sixth-most in a season for a rookie in Cardinals history.
