Cardinals vs Reds Key Matchups and Game Preview
Reds Ace on the Mound
Chase Burns has developed into Cincinnati's ace, carrying a 14-2 record, 2.47 ERA and 1.09 WHIP across 131 innings with 151 strikeouts, 46 walks and only 13 home runs allowed. That kind of workload and dominance gives the Reds a significant edge in this matchup.
Cardinals Rotation Struggles
Matthew Liberatore has struggled much more consistently for St. Louis, going 5-10 with a 5.07 ERA and 1.48 WHIP over 119 innings while surrendering 132 hits and 20 home runs. That gap is significant against a Cincinnati lineup built around power.
Cincinnati's Power Advantage
Despite batting only .226 as a team, Cincinnati has produced 163 home runs compared with St. Louis' 131. Sal Stewart has supplied much of that power with 26 home runs and 91 RBI while batting .258, and Elly De La Cruz enters hitting .259 with a .341 OBP and .470 slugging percentage.

Cardinals vs Reds Side and Over/Under Picks
Reds Spread Play
The Reds are priced at -140 on the moneyline and -1.5 at +144, while St. Louis sits at +131 and +1.5 at -175. Given Burns' dominant 2.47 ERA and 151 strikeouts against a Cardinals lineup that lacks Cincinnati's overall power, Reds -1.5 at +144 is the preferred side for this matchup.
Total Play for This Matchup
The total is set at 8.5 at -110 on both sides, and Under 8.5 at -110 is the lean here, as Burns should suppress St. Louis while Cincinnati may not need a large offensive output to separate against Liberatore.
- Side Pick: Reds -1.5 (+144)
- Total Pick: Under 8.5 (-110)
Final Score Prediction
Burns' ability to work deep and miss bats should limit Cincinnati's exposure to a depleted bullpen while keeping St. Louis off the board for long stretches.
- Final Score Prediction: Reds 5, Cardinals 2
