Cardinals at Cubs: Reading the Finale
Chicago came into the weekend at 71-50, while St. Louis sat at 61-60. The series finale today sees the Cubs bring out their best arm.
Shota Imanaga leads the staff in strikeouts and draws a lineup that has struggled to slug. St. Louis answers with Hunter Dobbins, whose 3.40 ERA looks tidy until you notice the 42 strikeouts behind it.
Dobbin misses few bats and hasn't carried deep innings, which puts a bullpen worked over two afternoon games back on the mound early.
Chicago's offense has been one of the NL's more productive, with Pete Crow-Armstrong leading the club in homers, RBI and average. He sits as a favorite when looking at MLB MVP odds.
- The Cubs also have something to chase: Kalshi gives them roughly 40% to take the NL Central against Milwaukee's 61%, with the Cardinals under 1%.
The Pick: Cubs at the Right Price
Kalshi priced Chicago at 62% for the opener and 59% for Saturday, moving off the pitching matchup rather than the standings. Imanaga should push the finale number higher, so expect the Cubs price to settle the low-to-mid 60s range.
Buy Cubs to win Yes under 65 cents. Above 68, the value flips and the Cardinals share is the better hold. Either way, trade the exit rather than praying on the ninth.
Live totals are the other spot worth watching, since the Wrigley wind rewrites run expectation by the half inning. Tail this pick backed by Action Network experts once you redeem Polymarket referral code ACTION.
Polymarket vs. Kalshi: Same Game, Different Cost
Check both prediction markets before you buy any shares. Across this series, the platforms have priced Cardinals-Cubs within a point of each other.
Polymarket had Chicago at 63 cents while Kalshi showed 62%, so the headline number rarely settles it. Kalshi charges a taker fee scaling with price, near a penny and a half per share in the low 60s.
Polymarket carries no separate trading fee, as cost sits inside the spread. On $20 of credit, the same Cubs share comes cheaper on Polymarket.
