Colorado Rockies vs St. Louis Cardinals Prediction and Picks, September 6, 2026

For tonight's game, we expect fewer than 11 total runs between the Colorado Rockies and the St. Louis Cardinals. Both teams have been decent against left-handed pitchers, but their overall hitting has been a bit inconsistent lately. The Rockies have only won 4 of their last 10 games and struggle at home, while the Cardinals are slightly better overall but still have their ups and downs. The numbers suggest a combined total closer to 10 runs, which gives us a good chance to hit the under. One risk is that both teams are capable of scoring quickly, but with the way they've been playing, it seems more likely they'll keep the score lower tonight.

Colorado Rockies vs St. Louis Cardinals: Colorado Rockies 1.5 Spread (-135)

The odds for the Rockies to win by 1.5 runs are looking tempting right now. Colorado has been solid against lefties this year, matching the league average, and they tend to perform better at home, even if their overall record isn't great. St. Louis has also been hitting well against left-handed pitchers, so this matchup feels pretty even. While the Rockies have only won 4 of their last 10 games, they do have a slight home advantage. The final margin could be very close, which makes this a risky bet. Just remember that both teams are playing at Coors Field, where scoring can get wild.

Colorado Rockies vs St. Louis Cardinals: Kyle Leahy Under 3.5 Pitcher - Strikeouts (-167)

Kyle Leahy is set to pitch for the Colorado Rockies at Coors Field, and we think he might struggle to get more than three strikeouts. The Rockies have been shaky at home this year, winning just under 30 games, and Leahy has faced tough competition lately. The St. Louis Cardinals are hitting well against left-handed pitchers, so Leahy could find it challenging to rack up those strikeouts. On the flip side, Leahy's strikeout numbers haven't been impressive lately. With the Cardinals hitting for a good average against lefties, there's a real chance he won't reach four strikeouts. It's not a guarantee he'll fall short, but the matchup doesn't favor him this time around.
