St. Louis Cardinals vs. Cincinnati Reds Prediction – August 19, 2026
The St. Louis Cardinals head to Great American Ball Park to take on the Cincinnati Reds in what shapes up to be a closely contested NL Central rivalry game. WP Baseball Predictor has crunched the numbers and issued its pick: Cardinals +1.5, backed by a 53.2% win probability against the Reds' 46.8%. Here is a full breakdown of what to expect on Wednesday night.
Starting Pitcher Matchup
Matthew Liberatore (Cardinals) – xFIP: 4.23
Matthew Liberatore takes the ball for St. Louis carrying an xFIP of 4.23, a figure that suggests he is a slightly below-average run-prevention arm by expected metrics. Liberatore will need to rely on command and sequencing to navigate a Reds lineup that, while not elite, is capable of making contact and generating offensive opportunities. His xFIP indicates some vulnerability, and the Reds will look to exploit any lack of sharpness early in the ballgame.
Chase Burns (Reds) – xFIP: 3.23
Chase Burns presents the more compelling profile on paper, posting an xFIP of 3.23 — a full run better than his Cardinals counterpart. That gap suggests Burns has been generating quality contact suppression and is pitching at an above-average level by expected metrics. The Cardinals' offense will face a genuine challenge against Burns, and quieting his performance early will be critical if St. Louis hopes to keep the run line in play.
Pitcher Matchup Edge: Reds
Burns holds a clear xFIP advantage in this matchup. The one-run difference in expected fielding-independent pitching between the two starters is meaningful, and on paper, Cincinnati's starter gives the home team a legitimate edge on the mound.
Why WP's Model Favours the Cardinals
Despite Burns' superior xFIP, WP Baseball Predictor's model sides with St. Louis at +1.5 for several reasons rooted in team-level performance. The Cardinals own a stronger overall pitching profile, posting a team FIP of 4.15 and a team ERA of 3.99, compared to the Reds' team FIP of 4.72 and ERA of 4.48. That gap indicates St. Louis' pitching staff as a whole is a more reliable unit, particularly when games extend into the bullpen.
Offensively, the Cardinals also hold a slight edge, with a team wOBA of 0.306 against the Reds' 0.303. While neither team is a powerhouse at the plate, St. Louis carries marginally better run-production quality. When the model weighs individual starter xFIP against broader team-level pitching and offensive metrics, the Cardinals emerge as the slight overall favourite. The +1.5 run line pick reflects confidence that St. Louis stays competitive and avoids a blowout loss even against a strong starter.
Injury Report and Impact
The injury landscape heading into this game leans heavier on the Cincinnati side, which factors into the model's lean toward St. Louis.
- Cardinals: Travis Honeyman (Undisclosed, 7-Day IL) is the lone notable absence for St. Louis, limiting their depth concerns heading into this game.
- Reds: Cincinnati is dealing with a more crowded injury list, including Julian Aguiar (Undisclosed, 7-Day IL), Jose Franco (Forearm, 7-Day IL), Garrett Hampson (Undisclosed, 7-Day IL), Brandon Leibrandt (Undisclosed, 7-Day IL), and Tony Santillan (Oblique, 15-Day IL).
The volume of Reds absences — particularly Santillan on the 15-Day IL — could impact Cincinnati's bullpen depth and positional flexibility if the game extends late. This is a meaningful consideration when evaluating the Cardinals' chances of covering the +1.5 run line.
Dark Horse Home Run Picks
Every game carries long-shot power potential, and here are the dark horse home run candidates worth watching on August 19:
- Cardinals – Joshua Báez: Keep an eye on Báez as a surprise power threat against Burns. A hitter capable of turning on a fastball in the right count could make noise in this spot.
- Reds – JJ Bleday: Bleday is the dark horse pick on the Cincinnati side. With the right pitch to drive, Bleday has the raw power to go deep and provide a momentum-shifting moment at Great American Ball Park.
Final Prediction
WP Baseball Predictor's model gives the Cardinals a 53.2% win probability and backs them at Cardinals +1.5. While Chase Burns presents a legitimate pitching challenge, St. Louis' superior team-wide pitching metrics, slight offensive edge, and a lighter injury report make them a reasonable side to back in a tight, competitive game. Expect a close, low-scoring affair with the Cardinals staying within the run line.
