Cubs vs Cardinals Predictions & Props to Bet on Sunday Night Baseball

The St. Louis Cardinals (30-25) host the Chicago Cubs (31-27) at Busch Stadium on May 31, 2026. First pitch is scheduled for 7:20 PM EST and will be aired on ESPN. These two teams have split the first two games of the series, with the Cardinals winning on Friday by a 6-5 score and the Cubs doing so on Saturday by 6-1.

The Cardinals enter as slight favorites on the moneyline mainly due to a marked pitching advantage, but the Cubs certainly have enough offense to pull the upset here against a divisional rival to take home the series.

In this betting breakdown, I will analyze the starting pitching matchups, statistical advantages, recent trends, and my top predictions for tonight’s game.

Cubs vs Cardinals Odds & Predictions

Odds as of 4 AM ET, May 31, 2026, from Caesars Sportsbook.

The Cubs enter this matchup as slight road favorites at -115 on the moneyline, while the Cardinals are priced as marginal -105 home underdogs. Looking at the opening lines, the runline has remained completely stagnant since it was released, holding firm at Chicago -1.5.

The game total has seen notable movement. The total originally opened at 9.0 runs but has since been bet down to 8.5. Despite the total ticking down half a run, the current juice has shifted to heavily favor the Over at -120. This suggests the sportsbook aggressively adjusted the juice to protect against an influx of volume expecting a high-scoring contest.

My primary prediction focuses on the St. Louis Cardinals Moneyline (-105), and this could be paired with the Over 8.5 Runs (-120). The crux of this analysis lies in the discrepancy in starting pitching. Chicago sends Jordan Wicks to the mound, and his limited 2026 sample size is highly concerning, while the Cardinals will send a struggling Matthew Liberatore to the mound. Given the overarching vulnerabilities of both starters, expecting a high-scoring affair that favors the home team is the most logical approach.

When looking at the prop market, my favorite angle is Jordan Walker Over 1.5 Total Bases (+116). Walker boasts a .557 slugging percentage and a .916 OPS. With 15 home runs and an average of 1.1 hits per game, Walker is perfectly positioned to exploit Wicks’ struggles and generate extra bases.

For bettors looking to diversify, another highly correlated prop is Jordan Wicks Under 14.5 Pitching Outs (+119). Considering his inflated WHIP and 18.69 hits allowed per nine innings, expecting Wicks to navigate through five full innings is a tall order. Alternatively, backing Matthew Liberatore Over 4.5 Strikeouts (-115) provides solid value. Liberatore has consistently demonstrated the swing-and-miss ability necessary to clear this modest threshold, even if his recent results have been far from inspiring.

Cubs vs Cardinals: Starting Pitchers & Team Statistics

To understand why the Over and the St. Louis moneyline hold significant value, we must examine the vulnerabilities of both starting pitchers. The numbers suggest an environment ripe for offensive production.

Chicago will hand the ball to Wicks, whose 2026 campaign has been poor in his extremely limited 4.1-inning sample size. The left-hander currently sports an 0-1 record with a 16.62 ERA and a 2.31 WHIP. Wicks is getting hit hard, allowing 18.69 hits per nine innings and an opponent batting average of .409. However, these numbers must be taken with a grain of salt since he’s made just one start and is not expected to struggle at this rate all season long.

On the other side, St. Louis turns to Liberatore. He brings a much larger body of work this season (56.2 IP) and a 2-3 record, but his underlying metrics show he is not immune to damage. With a 4.77 ERA, a 1.57 WHIP, and a .302 opponent batting average, he has consistently allowed runners on base.

However, Liberatore holds a distinct advantage over Wicks in his ability to pitch out of trouble. In his last 10 games, his strikeout rate has ticked up to 8.88 K/9, and he has the ability to eat up more innings, although Wicks’ one-start sample isn’t enough to draw meaningful conclusions.

At first glance, Chicago appears to have the offensive edge, plating 4.90 runs per game on the road compared to the St. Louis average of 3.89 runs per game at home. The Cubs also manufacture runs efficiently on the basepaths, edging out St. Louis in stolen bases per game.

Looking beneath the run-scoring surface unveils a power and contact mismatch leaning toward the home team. Despite scoring fewer overall runs, St. Louis boasts a superior home batting average (.243) to the Cubs (.236). However, Chicago has a higher OPS on the road (.711) than St. Louis has at home (.708). At the end of the day, both teams have their strengths on offense, putting even more emphasis on the pitching matchup.

More importantly, St. Louis hits the ball significantly harder. They average an 89.2 mph exit velocity at home, launching 1.21 home runs per game. Chicago’s pitching staff, meanwhile, has been vulnerable to the long ball, surrendering 1.44 home runs per nine innings.

Cubs vs Cardinals Public Betting Splits & Trends

Analyzing the betting handle and ticket distribution provides valuable insight into how the market views this matchup, per our MLB public betting data. The moneyline shows bettors overwhelmingly backing the road favorites. Chicago is drawing 62.8% of the betting tickets and 84.9% of the total money. St. Louis is seeing just 37.2% of the tickets and 15.1% of the stake.

By backing St. Louis on the moneyline, I am taking a contrarian stance, fading both the casual public and the larger betting handle that is currently driving the market toward Chicago.

When looking at the game total, the action is incredibly one-sided. The Over commands 92.7% of the tickets and 88.1% of the total stake. My prediction to back the Over aligns with both the public consensus and the heavy financial liability at the sportsbook.

Here are the most notable betting trends for both teams heading into tonight’s game:

• Chicago has struggled heavily, winning just 30.0% (3-7) of their last 10 games
• However, three of those wins have come in the Cubs’ last four games
• Chicago holds a 0.0% (0-6) win rate as the betting favorite over their last 10 contests
• The Under has cashed in just 37.9% of Chicago’s overall games this season
• St. Louis has secured a victory in only 30.0% (3-7) of their last 10 matchups
• St. Louis has posted a 28.6% (2-5) win rate as the underdog over their last 10 games
• The Over has hit in just 38.2% of St. Louis’ total games

Injury Report

Injuries play a pivotal role in shaping tonight’s betting landscape. Chicago is limping into this matchup with 10 players on the injured list, primarily affecting their pitching staff. Conversely, St. Louis is relatively healthier, managing just three active injuries.

The sheer volume of injuries on the Chicago pitching staff cannot be overstated. With frontline starters and critical bullpen pieces sidelined, their pitching depth is compromised. This organizational shortage explains why a struggling pitcher like Wicks is taking the mound.

Because Chicago lacks the healthy, high-leverage reinforcements to bail Wicks out if he exits early, St. Louis is positioned to exploit a depleted bullpen. This cascade of pitching injuries heavily reinforces my recommendation to bet the Over.

For St. Louis, the absence of Lars Nootbaar is a tough pill to swallow, as his plate discipline is a staple of their game plan. However, they still boast enough middle-of-the-order firepower to overcome these absences. Their offensive core remains intact enough to capitalize on the battered Chicago pitching staff.
