The St. Louis Cardinals vs Colorado Rockies Prediction for Saturday, September 5, 2026, points to the Colorado Rockies as the best moneyline value. Colorado is listed at +106 against the St. Louis Cardinals, who are priced at -128 at Coors Field. Kyle Leahy is expected to start for St. Louis, while Mason Adams is projected to take the mound for Colorado.

The Cardinals enter the matchup at 70-71, while the Rockies are 54-86. St. Louis has the significantly better pitching staff and defense, but Colorado’s offense has produced more runs per game and owns the better batting average, slugging percentage and overall run production.

The biggest factor behind the underdog pick is the combination of Coors Field, Colorado’s offense and the plus-money price. The Rockies average 4.68 runs per game and have 1,204 hits, 254 doubles and 154 home runs. They are also hitting .253 as a team.

Colorado’s pitching remains a major concern, but at +106, the Rockies only need to win the game outright to cash the moneyline.

Pick: Colorado Rockies +106

St. Louis Cardinals vs Colorado Rockies Prediction: Direct Answer

The best bet is Colorado Rockies +106.

St. Louis has the better record, stronger pitching staff and better defense, but the Cardinals are not receiving a massive price discount despite facing a Rockies team that has been considerably more productive offensively.

Colorado is averaging 4.68 runs per game, ranking eighth in MLB, while St. Louis averages 4.5 runs per game. The Rockies also have a .253 batting average and .415 slugging percentage, compared with St. Louis at .242 and .384.

The pitching matchup favors St. Louis. The Cardinals have a 4.24 team ERA and 4.08 FIP, while Colorado owns a 5.42 ERA and 4.79 FIP.

However, the game is being played at Coors Field, where the offensive environment can make a large difference. Colorado also has the better offensive profile and enters at plus money.

For those reasons, Colorado +106 is the preferred value play.

St. Louis Cardinals vs Colorado Rockies Prediction and Odds

• Game: St. Louis Cardinals vs Colorado Rockies
• Date: Saturday, September 5, 2026
• Location: Coors Field, Denver, CO
• TV: Rockies.TV
• St. Louis Moneyline: -128
• Colorado Moneyline: +106
• Total: 9 runs
• St. Louis Starting Pitcher: Kyle Leahy
• Colorado Starting Pitcher: Mason Adams
• Best Bet: Colorado Rockies +106

The Cardinals are modest road favorites, but the moneyline is close enough to make the underdog attractive.

Colorado is 54-86 and has one of the worst pitching staffs in baseball, but the Rockies have still scored 655 runs and rank eighth in MLB in runs per game.

That offense becomes especially relevant at Coors Field.

St. Louis Cardinals vs Colorado Rockies Team Comparison

St. Louis has scored 633 runs this season and averages 4.5 runs per game. The Cardinals have 1,149 hits, 199 doubles and 150 home runs while batting .242 with a .316 OBP and .384 slugging percentage.

Colorado has scored 655 runs and averages 4.68 runs per game. The Rockies have 1,204 hits, 254 doubles and 154 home runs. They are batting .253 with a .323 OBP and .415 slugging percentage.

Colorado therefore has the better offensive numbers across several important categories.

The Cardinals have the better pitching and defense, but the Rockies’ offensive advantage makes them dangerous at home.

St. Louis Cardinals Offensive Profile

The Cardinals have:

• .242 team batting average
• .316 OBP
• .384 slugging percentage
• 4.5 runs per game
• 1,149 hits
• 199 doubles
• 150 home runs
• 633 runs scored
• 615 RBI
• 447 walks
• 1,110 strikeouts

St. Louis has been a relatively average offense this season.

The Cardinals’ .242 batting average is respectable, but their .384 slugging percentage ranks below Colorado’s .415.

St. Louis also has significantly fewer doubles, with 199 compared with Colorado’s 254.

Colorado Rockies Offensive Profile

Colorado has:

• .253 team batting average
• .323 OBP
• .415 slugging percentage
• 4.68 runs per game
• 1,204 hits
• 254 doubles
• 154 home runs
• 655 runs scored
• 630 RBI
• 448 walks
• 1,220 strikeouts

The Rockies’ offense has been one of the more productive groups in baseball despite their overall record.

Their 4.68 runs per game ranks eighth in MLB, and their .253 batting average is considerably better than St. Louis’ .242.

Colorado also has 55 more doubles than St. Louis.

That extra-base production is particularly important in a hitter-friendly environment.

Kyle Leahy vs Mason Adams

The starting-pitcher matchup is a major part of this St. Louis Cardinals vs Colorado Rockies Prediction.

Kyle Leahy

Leahy has accumulated 267 MLB innings and 233 strikeouts during his career.

His career statistics include:

• 15-8 record
• 3.40 ERA
• 3.35 FIP
• 1.257 WHIP
• 255 hits allowed
• 81 walks
• 233 strikeouts

Leahy has been considerably more effective than the typical Colorado pitcher based on these career numbers.

His 3.40 ERA and 3.35 FIP give St. Louis a significant starting-pitching advantage.

He also has a solid 1.257 career WHIP, indicating an ability to limit baserunners.

Mason Adams

Adams has only nine MLB innings of experience.

His career numbers include:

• 0-0 record
• 3.00 ERA
• 3.00 FIP
• 1.444 WHIP
• 8.0 hits per nine innings
• 10 strikeouts
• 5 walks
• 8 hits allowed

The sample size is extremely small, so Adams’ 3.00 ERA should not be treated as evidence that he is a proven major-league starter.

His 1.444 WHIP and 2.00 K/BB ratio provide some warning signs.

St. Louis has a clear starting-pitcher advantage.

However, Colorado’s selection at +106 is based on the total matchup rather than expecting Adams to outpitch Leahy.

St. Louis Pitching vs Colorado’s Offense

St. Louis has a much stronger pitching staff.

The Cardinals have posted:

• 4.24 ERA
• 4.08 FIP
• 1.35 WHIP
• 1,113 strikeouts
• 484 walks
• 140 home runs allowed
• 642 runs allowed
• 1,212 hits allowed

The 4.24 ERA ranks 20th in MLB, so the Cardinals have not been elite, but they are considerably better than Colorado’s pitching staff.

Leahy gives St. Louis an additional advantage because his career ERA and FIP are both around 3.4.

The challenge is that Colorado’s offense has been productive all season.

The Rockies have scored 655 runs and average 4.68 per game. They also have a .253 batting average and .415 slugging percentage.

At Coors Field, Colorado has an opportunity to turn those offensive strengths into an advantage.

Colorado Pitching vs St. Louis’ Offense

This is the biggest weakness for the Rockies.

Colorado has a:

• 5.42 ERA
• 4.79 FIP
• 1.516 WHIP
• 951 strikeouts
• 462 walks
• 188 home runs allowed
• 795 runs allowed
• 1,404 hits allowed

The Rockies rank near the bottom of MLB in virtually every major pitching category.

Their 5.42 ERA ranks 29th, while their 1.516 WHIP is particularly problematic.

Colorado has also allowed 795 runs, meaning St. Louis should have opportunities to score.

The good news for the Rockies is that the Cardinals have not been an elite offensive team. St. Louis averages 4.5 runs per game and owns only a .384 slugging percentage.

That gives Colorado a path to win if its offense can take advantage of Coors Field.

Bullpen Comparison

The Cardinals have the advantage in bullpen holds, but neither relief corps has been particularly dominant in save situations.

St. Louis has a 62.1% save percentage, with 41 saves and 25 blown saves in 66 opportunities. The Cardinals have recorded 92 holds, ranking fourth in MLB.

Colorado has a 58.5% save percentage, with 56 holds and 22 blown saves.

The Rockies’ relievers have inherited 217 runners, with 30.4% eventually scoring.

St. Louis has inherited 212 runners, with 38.7% scoring.

The Cardinals therefore have the better save percentage and more holds, but Colorado has actually allowed a smaller percentage of inherited runners to score.

Neither bullpen creates a compelling reason to abandon the underdog.

Defensive Comparison

St. Louis has a major defensive advantage.

The Cardinals own a .989 fielding percentage, ranking fourth in MLB, and have converted 69.1% of balls in play into outs.

Colorado has a .982 fielding percentage, ranking 27th, and its defensive efficiency of 66.9% ranks 30th.

The Cardinals have also turned 136 double plays compared with Colorado’s 113.

This is another clear statistical advantage for St. Louis.

However, the Rockies’ offensive production and home-field environment can offset some of that defensive difference.

Why Bet Colorado Rockies +106?

There are several reasons to consider Colorado as the underdog.

1. Colorado Has the Better Offensive Numbers

The Rockies average 4.68 runs per game, ranking eighth in MLB.

St. Louis averages 4.5 runs per game.

Colorado also has the higher batting average, OBP and slugging percentage.

2. Coors Field Creates a Significant Home-Field Angle

The game is being played at Coors Field, one of the most offense-friendly environments in Major League Baseball.

That matters because Colorado’s greatest strength is its offense, while its greatest weakness is pitching.

A high-scoring home environment can amplify the Rockies’ offensive strengths.

3. Colorado Has More Hits and Doubles

The Rockies have accumulated 1,204 hits and 254 doubles, compared with St. Louis at 1,149 hits and 199 doubles.

That extra-base production provides Colorado with multiple ways to generate runs.

4. Colorado Is Plus Money

The Rockies are priced at +106.

That means bettors are getting a positive-moneyline return on a team capable of producing runs at one of the league’s most hitter-friendly parks.

5. St. Louis Is Not an Elite Offensive Team

The Cardinals have a .242 batting average and .384 slugging percentage.

Their offense is good enough to score, but it has not been among the league’s most dangerous groups.

That reduces the risk associated with backing Colorado’s weaker pitching staff.

St. Louis Cardinals vs Colorado Rockies Prediction: Total of 9

The betting total is 9 runs.

This is an intriguing number given the location and the two pitching staffs.

Colorado has allowed 795 runs and owns a 5.42 ERA. The Rockies also have a 1.516 WHIP.

St. Louis, meanwhile, has a 4.24 ERA, but Colorado averages 4.68 runs per game and plays at Coors Field.

The Cardinals average 4.5 runs per game, so both offenses have realistic paths to contributing to a high-scoring game.

However, the preferred wager remains Colorado +106 rather than the total.

The moneyline provides a cleaner way to take advantage of the Rockies’ offensive profile and home-field setting.

What Is the Best Bet for Cardinals vs Rockies?

The best bet is Colorado Rockies +106.

St. Louis has the better record, pitching staff, bullpen save percentage and defense. Those factors make the Cardinals the logical favorite.

But the line is close enough that Colorado deserves consideration.

The Rockies rank eighth in MLB in runs per game and have better offensive numbers than St. Louis in batting average, OBP and slugging percentage.

At Coors Field, those strengths become even more relevant.

The Rockies also have a plus-money price, making them the preferred value side.

St. Louis Cardinals vs Colorado Rockies Prediction: Final Pick

The final pick for Saturday’s matchup is:

Colorado Rockies +106

This is not a pick based on Colorado having the better overall team.

St. Louis clearly has the superior pitching staff. The Cardinals have a 4.24 ERA compared with Colorado’s 5.42, while Leahy has a career 3.40 ERA and 3.35 FIP. St. Louis also has a .989 fielding percentage, compared with Colorado’s .982.

But baseball betting is about the matchup and the price.

Colorado averages 4.68 runs per game, ranking eighth in MLB. The Rockies are batting .253, slugging .415 and have accumulated 1,204 hits and 254 doubles.

St. Louis averages 4.5 runs per game and has a .384 slugging percentage.

The Rockies also get to play at Coors Field, where their offensive strengths can become particularly valuable.

Mason Adams is the biggest concern for Colorado, but his nine-inning MLB sample is too small to draw strong conclusions from his 3.00 ERA. St. Louis will have the more established starter in Leahy, but Colorado has enough offensive firepower to make this a competitive game.

With the Rockies available at +106, the price is attractive enough to take the home underdog.
