The Cubs already have this series in hand, but St. Louis has a puncher’s chance to salvage the finale behind a pitcher who’s quietly one of the more reliable arms in the NL Central.

Quick take:
Pick: Cubs -1.5
Why: Shota Imanaga has been sharp all July and Chicago’s lineup is deeper than St. Louis’s from top to bottom
The number to watch: Pete Crow-Armstrong’s 24 home runs

Chicago rolls into Busch Stadium at 61-47, sitting second in the NL Central and holding a 2-1 edge in this four-game set after Wednesday’s 2-3 loss snapped a two-game win streak in the series. St. Louis, on the other hand, is treading water at 54-54, fourth in the division and clinging to the fringes of relevance with a roster that’s shown flashes but hasn’t strung together the consistency to climb back into the race. The Cardinals did just take Wednesday’s game, so there’s a sliver of momentum heading into the rubber match, but this is still a team playing out the string more than chasing October.

This is the 10th meeting between these two clubs this season, and surprisingly, St. Louis actually leads the season series 5-4 despite the gap in the standings — a reminder that division rivals rarely play to form when they see each other a dozen times a year.

What the Market Is Saying About This Finale

Books have this one closer than you’d expect given the standings gap. St. Louis is sitting as a moneyline favorite in the -120 range with Chicago going off around +100 to +102, and the total is set at 8.5 runs. The Cubs, meanwhile, are getting run-line respect at -1.5 (+172), which tells you the market expects Chicago’s lineup to eventually pull away even if the game starts tight. That gap between the moneyline lean toward St. Louis and the spread lean toward Chicago is the interesting tension here — it’s less “who wins” and more “by how much,” and recent history in this series backs the over-the-hump theory for the Cubs, who blew this matchup open 17-1 back on July 3rd.

Imanaga’s Command vs. a Cardinals Lineup Missing Its Punch

Shota Imanaga gets the ball for Chicago, and his 3.79 ERA understates how good he’s been of late — the Cubs are 6-2 in his last eight starts with a set spread, and his fastball command has been the separator against contact-heavy lineups like this Cardinals group. Andre Pallante counters for St. Louis at 11-6 with a 3.77 ERA over 112.1 innings, a workhorse season by volume, but he’s allowed three or more earned runs in three of his last five outings — exactly the kind of stretch that invites a Cubs lineup that just posted a 17-run outburst against this same pitching staff to do damage again.

Pete Crow-Armstrong is the engine here. He’s hitting .284 with 19 doubles, six triples, 24 home runs, 55 walks and 63 RBI, and he’s been the single most complete player on the field in this series. Nico Hoerner has cooled from his career norms — .240 with just four home runs — but he’s still swiped 14 bases and remains a pest at the top of the order. On the other side, Jordan Walker has been one of the lone bright spots for St. Louis, hitting near .290 with 22 home runs and 77 RBI, proof that even a middling Cardinals season has produced at least one legitimate building block.

Other Game Picks

Pallante has allowed three-plus earned runs in three of his last five starts.

That trend matters against a Cubs offense that has already shown it can erupt against this exact pitching staff. Chicago doesn’t need a heroic outing from Imanaga to win this one comfortably — it just needs Pallante’s recent shakiness to continue for even five or six innings before St. Louis’ bullpen gets exposed.

St. Louis will need a much cleaner start from Pallante than he’s given recently to keep this series finale competitive.

Prediction and Best Bet

Chicago has the better arm on the mound, the hotter bat in the middle of the order, and a division race to stay sharp for down the stretch. St. Louis has shown it can hang for stretches, but the recent form for its starter points toward another game that gets away from the Cardinals in the middle innings.
