Chicago Cubs vs St. Louis Cardinals Preview - MLB Sunday

Matchup Overview

The Chicago Cubs travel to take on the St. Louis Cardinals on Sunday, May 31, 2026 in MLB action. Rain Man forecasts St. Louis Cardinals to outscore Chicago Cubs by ~0.5 runs. Projected combined score: ~9.5 runs. Here's how the model got there: The Cardinals' home-field advantage and a pitching edge from Matthew Liberatore over Jordan Wicks give them the narrow edge in what is otherwise a coin-flip game between two teams that project similarly by STEAMER.

Key Storylines

• Liberatore holds a career pitching edge over Wicks in this matchup
• Cardinals' 18.1 wRC+ and 18.1mph EV edges in current season data
• Cubs' STEAMER projections (bat wRC+ 108.7) superior to Cardinals (103.7)
• Busch Stadium's 0.96 run factor and 0.93 HR factor suppress scoring
• Cardinals' offense benefits from Ivan Herrera's 0.392 SecA and Jordan Walker's 0.423 SecA

Current Markets

Here are the current markets for this matchup:

• Moneyline: St. Louis Cardinals -102 | Chicago Cubs -116
• Spread: St. Louis Cardinals 1.5 | Chicago Cubs -1.5
• Total: Over/Under 8.5

Spread Analysis

The market anchors the Cardinals at 1.5 runs, and Rain Man's model lands right on that number. The Cardinals hold an 18.1 wRC+ edge and 18.1mph EV edge in current season data, though the Cubs' STEAMER projections (bat wRC+ 108.7, pit ERA 4.06) are actually superior to St. Louis (bat wRC+ 103.7, pit ERA 4.14). Liberatore's career edge over Wicks at the plate gives the Cardinals a slight pitching advantage that justifies the spread. Busch Stadium's 0.96 run factor and 0.93 HR factor suppress scoring modestly, which works in the Cardinals' favor since they project to win by a narrow margin. the model's value fades if current markets move past ~2.0 runs.

Total Analysis

The Bill James model projects 11.9 runs, but this must be adjusted downward for Busch Stadium's run factor of 0.96 and HR factor of 0.93, landing closer to 11.3. However, the market total of 8.5 reflects the pitcher-friendly environment and the Liberatore-Wicks matchup. This could turn into a high-scoring affair if the Cardinals' offense breaks through — Busch Stadium is neutral to slightly below average, not a true pitcher's park. Tempo could drive this one, particularly if the Cardinals' power-heavy lineup (Walker, Herrera, Gorman) finds early success. This projects more like a grind than a shootout, with defensive pressure likely keeping this one in check. Rain Man's value fades if current markets move to ~8.0 (or beyond).

Injury Report

Cardinals are without Willson Contreras (C) and Brendan Donovan (LF), which impacts their defensive stability and outfield depth. Lars Nootbaar remains on the 10-day IL recovering from heel surgery. Masyn Winn is day-to-day with an arm issue. Cubs have lost Justin Steele (SP) to injury, but Jordan Wicks has been cleared as the probable starter. The Cardinals' injury situation is more impactful, particularly the loss of two regular position players.
