Matchup Analysis
Cavalli brings a dominant strikeout trend
Cade Cavalli has recorded at least seven strikeouts in each of his last seven starts, giving Washington a swing-and-miss edge against St. Louis. His recent form includes an eight start stretch where he posted a 1.69 ERA while holding opponents to a .187 batting average.
SourceLeahy utilized as an opener
Kyle Leahy is scheduled for approximately 45 pitches and three innings, requiring substantial early bullpen coverage for St. Louis. This workload forces the Cardinals to rely on their relief depth much earlier than a traditional starting pitching matchup would dictate.
SourceWetherholt return boosts Cardinals contact
St. Louis activated JJ Wetherholt from the 10-day injured list following right-wrist tendinitis. His presence adds a reliable on-base and contact option to a lineup that is currently navigating several day-to-day injuries to key starters.
SourceSt. Louis lineup health concerns
Joshua Baez is considered day-to-day with left-side tightness, while Masyn Winn and Ivan Herrera have recently missed time for rest. Bettors should verify the final lineup card before evaluating Cardinals team totals or individual hitter props.
SourceComparative starter metrics
Cavalli enters at 12-5 with a 3.12 ERA and 1.17 WHIP, while Leahy carries a 10-4 record with a 3.33 ERA and 1.31 WHIP. While the ERAs are similar, Washington holds a significant advantage in starter longevity and WHIP.
SourcePick Ideas
Nationals First-Five Moneyline
Washington is the preferred side in the first half of the game because Cade Cavalli provides a consistent six to seven inning workload. This contrasts with St. Louis using Kyle Leahy as an opener for only three innings, creating more stability for the Nationals early.
Cavalli Strikeout Over
Target the over on Cavalli's strikeout props if the line is reasonable, as he has cleared the seven strikeout mark in seven consecutive starts. St. Louis has recently struggled with a 4-6 record over their last ten games, suggesting their hitters are vulnerable to high-upside swing-and-miss pitchers.
Leahy Outs Recorded Under
The under on Leahy's outs is a primary consideration given the specific team report that he is capped at 45 pitches. With an expected exit after roughly three innings, he is unlikely to pitch deep enough to clear standard starter-level out totals.
Cardinals Team Total Under
A team total under for St. Louis is worth looking at if Baez or other key starters remain out of the lineup. The combination of Cavalli's 1.69 ERA in his best stretches and the Cardinals' current two-game losing streak limits their offensive ceiling.
