The St. Louis Cardinals close out their road series against the Colorado Rockies on Sunday, September 6, with a 3:10 p.m. ET first pitch at Coors Field in Denver. Kyle Leahy gets the start for St. Louis opposite Colorado's Tanner Gordon in what figures to be a high-altitude afternoon with playoff positioning still in play during the final stretch of the regular season.

Cardinals vs. Rockies Starting Pitchers: Kyle Leahy vs. Tanner Gordon
Kyle Leahy draws the assignment for the Cardinals in this series finale. Leahy has worked his way into the St. Louis rotation and will need to be sharp against a Rockies lineup that always carries extra teeth at Coors Field. The thin mountain air in Denver is unforgiving for pitchers who leave the ball over the plate, and Leahy will have to work with precision to keep the Cardinals in this one from the jump.
Tanner Gordon takes the hill for Colorado. Like Leahy, Gordon is a younger arm still carving out his place in the big leagues. When two developing starters meet at Coors Field, the bullpens on both sides tend to become a major factor early — managers rarely let pitchers work deep into games in that ballpark when command wavers even slightly.
Keys to Watch for the Cardinals on Sunday
- Control the strike zone early. Leahy cannot afford to walk hitters at altitude. Extra-base hits at Coors are painful enough — free baserunners compound that problem in a hurry.
- Make Gordon work. The Cardinals' offense needs to see pitches, grind at-bats, and force Gordon out of the game before Colorado can turn to a fresh bullpen arm. Patient at-bats are critical in the early innings.
- Capitalize on the short porch. Coors Field rewards gap-to-gap hitting. St. Louis needs to attack the baseball and not let the unique dimensions of the park become a mental obstacle.
- Bullpen management. With a developing starter on the mound, Cardinals manager Oliver Marmol will likely need multiple relievers. How St. Louis manages its bullpen depth in a potential high-scoring environment will go a long way toward determining the outcome.
Series Finale Prediction
Coors Field games are almost always unpredictable, and Sunday's matchup between two younger starters only adds to that volatility. Colorado plays its home park well, but the Cardinals have enough offensive firepower to stay in any game regardless of the venue. Expect a back-and-forth afternoon with both bullpens heavily involved. St. Louis has the motivation of a late-season regular season push and should find a way to split or take the series. Cardinals 7, Rockies 5.
