The Chicago Cubs (60-46) roll into Busch Stadium on Tuesday as narrow favorites over a St. Louis Cardinals club (53-53) that has lost its offensive footing. Chicago sits firmly in the National League playoff picture.
St. Louis, by contrast, has dropped seven of its last 10 and now faces real trade-deadline pressure. The moneyline is close to a coin flip, and the arms tell a different story than the standings. Our read points toward a quieter night than the number suggests, and St. Louis right-hander Michael McGreevy is the reason. Here is the full card.

Chicago Cubs vs. St. Louis Cardinals Betting Preview
The pitching matchup is the place to start, and it does not favor the team the market prefers. Cardinals right-hander Michael McGreevy carries a 3.07 ERA and a 1.128 WHIP into his 21st start. He is a contact-oriented strike-thrower who limits free passes and works efficiently. His last time out, he allowed four earned runs on seven hits over 6⅓ innings against Arizona. That line was rougher than his season numbers, but the underlying profile stays strong.
Chicago counters with veteran right-hander Colin Rea, who owns a 4.85 ERA and a 6.9 K/9 across 17 starts. Rea has been serviceable rather than sharp. He surrendered four earned runs over five innings against Detroit in his most recent outing, and opponents are hitting .271 against him. On paper, McGreevy is the better arm tonight.
The lineups complicate the picture. The Cubs enter red-hot at the plate, with 12 home runs and a .456 slugging mark over their last 10 games. The Cardinals have gone cold, managing just four homers and a .298 slugging figure in the same stretch. Chicago also won Monday’s series opener 7-3. So the better team and the hotter bats belong to the visitors, even as the better starter belongs to the home side.
Health matters here too. Chicago is navigating a long list of absences, including several arms with elbow trouble. St. Louis is comparatively healthier on the mound. That gap could surface late if either bullpen is pressed into heavy work.

Cubs vs. Cardinals Prediction — Will the Runs Actually Come?
The first question in this game is how many runs it produces, and the pitching points toward restraint. McGreevy does not miss many bats, but he rarely walks hitters, and traffic-free innings hold scoring down. The Cubs are dangerous when they get something to drive. However, a strike-thrower who dictates counts can navigate even a hot lineup when his command is on.
The Cardinals’ bats are the other half of the equation. St. Louis has been quiet for two weeks, and Rea, for all his blemishes, has enough to keep a slumping order in check into the middle innings. Busch Stadium supports the same idea. It has long played as a neutral-to-pitcher-friendly park rather than a launching pad, so well-struck balls that leave other yards can die on the track here.
The other side has teeth. Rea’s 4.85 ERA invites a crooked number, and Chicago’s power surge can turn one mistake into a three-run swing. Bullpen work could also tip the count if either starter exits early. This read hinges on McGreevy holding a hot lineup down while the Cardinals stay cold, and a single big inning can flip it.
The Pick: Under 9 (-120)
Cubs vs. Cardinals Best Bet — Is the Public on the Wrong Side?
The market read is the most interesting angle in this game. Roughly three-quarters of public moneyline bets sit on the Cubs, and the number has nudged from -114 to -116 in Chicago’s direction. That is money moving with the crowd, not against it, so there is no hidden sharp signal pushing the favorite. It simply reflects a popular team playing well, a pattern we also flagged in our take on the series opener.
That leaves a familiar situation. The home side has the better starter tonight and is available at a near-even price, while the public loads onto the visitor. McGreevy’s edge over Rea is the kind of gap that often matters more than reputation, and Busch Stadium is a comfortable spot for St. Louis. When a pick’em-range home team draws only a small share of the money, the value tends to sit with the quiet side.
The case against is straightforward. The Cardinals’ offense has been dreadful, and a strong start can be wasted if the lineup cannot scratch across runs against Rea. Chicago is the better team, won Monday, and has every reason to be favored. This is a value-driven lean on price and pitching, not a claim that St. Louis is the stronger club.
The Pick: Cardinals Moneyline (-104)
Final Thoughts and Bonus Angle
A few things will decide whether these leans land. Watch McGreevy’s efficiency early. If he is working quick, low-pitch innings, both positions gain strength. Watch the Cubs’ approach as well. A patient, disciplined night from Chicago’s hitters would stress McGreevy’s pitch count and could hand the game to the bullpens sooner than the Cardinals want.
The late innings are the swing point. Chicago’s injury-thinned staff has to protect any lead, and St. Louis has struggled to mount comebacks during its cold stretch. If the game is tied or close after six, a Cardinals bullpen against a scuffling Chicago offense is the scenario that supports both of our positions. If Rea escapes early trouble and the Cubs’ power plays, the card busts in a hurry.
To recap the card, the primary play is Under 9 (-120), and the secondary play is the Cardinals on the moneyline (-104). Both rest on the same idea: Michael McGreevy giving St. Louis quality innings and keeping a hot Chicago lineup in the yard. That shared dependence is worth stating plainly. If McGreevy struggles, both positions are in trouble at once.
