Projections for the Cardinals-Cubs
Let’s look at the morning line and see where we can find an edge. If you want to put those promotional credits to work, the prop market for tonight’s St. Louis Cardinals vs. Chicago Cubs matchup is loaded with value. I’m focusing on starting pitcher strikeout props and the hit lines for some of the biggest bats taking the field at Wrigley. Here is what we’re working with:
| Player | Hits | Strikeouts |
|---|---|---|
| Shota Imanaga (CHC) | N/A | O/U 4.5 (Over -140 / Under +108) |
| Kyle Leahy (STL) | N/A | O/U 4.5 (Over +121 / Under -157) |
| Nico Hoerner (CHC) | O/U 0.5 (Over -241 / Under +177) | N/A |
| Pete Crow-Armstrong (CHC) | O/U 0.5 (Over -247 / Under +179) | N/A |
| Jordan Walker (STL) | O/U 0.5 (Over -233 / Under +170) | N/A |
| Alex Bregman (CHC) | O/U 0.5 (Over -216 / Under +159) | N/A |
| Seiya Suzuki (CHC) | O/U 0.5 (Over -200 / Under +149) | N/A |
| Ian Happ (CHC) | O/U 0.5 (Over -159 / Under +120) | N/A |
| Dansby Swanson (CHC) | O/U 0.5 (Over -152 / Under +113) | N/A |
| Michael Conforto (CHC) | O/U 0.5 (Over -142 / Under +107) | N/A |
Prop Breakdown & Matchup Trends
When I’m building a slip, I love to key on players with strong historical data. For tonight, Nico Hoerner is an excellent candidate to back for the Over on his 0.5 hits line. Hoerner has successfully exceeded 0.5 hits in six straight games against the St. Louis Cardinals, averaging 1.3 hits per game in those contests. He comes into tonight hot, clearing the total in five of his last six overall. We’re definitely locking him into our lineups.
On the bump, the data points firmly to the Under for Cardinals pitcher Kyle Leahy. At a 4.5 strikeout line, taking the Under (-157) looks like the smart play. Leahy has failed to exceed 4.5 Ks in five consecutive starts against the Cubs, posting a meager 0.4 average in those matchups.
Conversely, I’m eyeing the Over for Cubs starter Shota Imanaga on his 4.5 strikeout line (-140). While he’s had a spotty track record over his last five regular-season outings, he flat-out dominates this specific opponent. Imanaga has cleared 4.5 strikeouts in two straight games against St. Louis, punching out an average of 6.5 Cardinals batters. That’s the kind of edge we look for.
Finally, sometimes the best bet is knowing who to fade. I’m fading Ian Happ in the hits market tonight. Happ has hit a wall against Cardinals pitching, failing to record a single hit in four straight games against St. Louis. Leaving him out of our slips is a calculated move that could help us chase that bigger payout.
