More MLB picks: St. Louis Cardinals · Chicago Cubs

Chicago has averaged 8.2 runs per game across its last five, but this MLB prediction highlights a Cardinals team that has quietly steadied at 4.4 runs per game in the same stretch. While the Cubs’ recent scoring looks explosive, their 4–6 mark across the last 10 shows vulnerability, particularly against divisional opponents familiar with their tendencies. St. Louis enters with a balanced offensive core that can punish lapses, and the data points toward them being undervalued against a Cubs side prone to volatility.

Team Analysis

St. Louis Cardinals

The Cardinals sit at 78–83 overall, but their last 10 games at 5–5 with 4.1 runs per game show a lineup finding balance late in the season. Their last five at 2–3 with 4.4 runs per game indicate they are generating enough offense to stay competitive, especially with Alec Burleson and Ivan Herrera delivering steady production. On the road they have struggled at 34–46, yet that lower baseline creates value when their offense clicks against familiar divisional pitching.

St. Louis has shown resilience despite inconsistency, and the numbers suggest they are positioned to capitalize on a Cubs side that has leaked runs recently. Ivan Herrera’s ability to sustain rallies combined with Burleson’s timely hitting keeps them dangerous in late-game spots. Even with road challenges, the Cardinals’ current scoring pace is enough to make them the sharper betting angle against a Cubs team that has dropped six of its last 10.

Chicago Cubs

The Cubs’ 91–70 record reflects strong season-long results, but their 4–6 mark over the last 10 shows inconsistency when it matters most. Their last five games at 3–2 with 8.2 runs per game highlight offensive firepower, yet defensive lapses have left them vulnerable. Seiya Suzuki’s run production remains critical, but the recent trend shows that scoring alone hasn’t translated to consistent wins.

At home, the Cubs have been formidable with a 49–31 record, but their recent form suggests regression against opponents who can extend innings. Michael Busch and Pete Crow-Armstrong drive the power numbers, though the team’s volatile results make them less reliable from a betting standpoint. When facing a Cardinals squad with balanced hitting, Chicago Cubs’ heavy reliance on high-scoring outputs makes them a riskier side.

  • Batting Average: 0.249
  • Total Runs Scored: 784
  • Home Runs: 218
  • OBP: 0.321
  • SLG: 0.429

Moneyline Betting Prediction

The Cardinals’ steadier recent form paired with balanced run production makes them a sharper side than the Cubs, whose volatility has cost them six of their last 10. With Burleson and Herrera providing dependable offense and the Cubs struggling to convert scoring into consistent wins, the betting edge lies with St. Louis to take control of this matchup.

We rate the St. Louis Cardinals at +140 as the right side at current form.
