Jordan Montgomery picked up his third win in as many starts with St. Louis, and Nolan Gorman drove in three runs to lead the Cardinals to a 5-1 win over the Colorado Rockies on Wednesday night.

St. Louis won for the 12th time in 13 home games and beat Colorado for the 11th straight time at home while improving to a season-best 14 games over .500 at 65-51.

Colorado lost its fourth in a row and has dropped 18 of 26 since the All-Star break.

Montgomery (6-3), who was acquired from the New York Yankees for outfielder Harrison Bader on Aug. 2, gave up one run on six hits in 5 2/3 innings. He struck out eight. He is 3-0 with an 0.54 ERA in three starts with St. Louis. The lefthander has struck out 17 and walked just three in 16 2/3 innings.

Gorman capped off a two-run first-inning outburst with a ground-rule double off starter German Marquez (6-10). Arenado got the ball rolling with a run-scoring double as four of the first five batters reached against Marquez, who gave up three runs on seven hits over six innings.

Gorman pushed the lead to 3-1 with a run-scoring ground out in the fifth. Brendan Donovan and Paul Goldschmidt singled to begin the inning. Gorman added a run-scoring hit in the seventh.

Jose Iglesias had two hits for Colorado, which has been held to one run or less six times since July 26. His second-inning double extended the franchise record to 37 successive games with a double.

Marquez had allowed two earned runs or less in five of his previous six starts.

Adam Wainwright (8-8, 3.27) will face RHP Antonio Senzatela (3-6, 4.67) in the third and final game of the series on Thursday afternoon. Wainwright carried a no-hitter into the seventh inning of his last start against Milwaukee on Saturday. He struck out eight and allowed just three hits in a nine-inning no decision. Senzatella had recorded four successive quality starts.
