Cardinals vs. Yankees Prediction – August 3, 2026

The St. Louis Cardinals travel to New York to face the Yankees in what WP Baseball Predictor projects as one of the more lopsided matchups on the MLB schedule this week. With a 73.4% win probability assigned to the home side, the model firmly backs the Yankees moneyline as the play on August 3, 2026. Here's a full breakdown of why.

Starting Pitcher Matchup: Schlittler Dominates the Narrative

The pitching matchup is the clearest reason New York enters this game as a strong favourite, and the numbers tell a compelling story.

Cam Schlittler (Yankees)

Schlittler takes the mound carrying an elite xFIP of 2.60 — a mark that places him among the most effective starters in the league by that measure. Expected Fielding Independent Pitching strips away the noise of defense and luck, and Schlittler's 2.60 figure suggests he is generating weak contact and missing bats at an exceptional rate. For Cardinals hitters, this is an extremely difficult assignment.

Michael McGreevy (Cardinals)

McGreevy counters with an xFIP of 4.16, a number that signals meaningful vulnerability against a lineup with the offensive profile New York possesses. While not a liability by any absolute standard, the 1.56-point gap in xFIP between the two starters is substantial and reflects a genuine talent mismatch at the top of the lineup card on this particular day.

Why WP's Model Favours the Yankees

The WP Baseball Predictor's 73.4% win probability for New York is grounded in advantages that extend beyond the mound. Consider the team-level metrics:

  • Yankees wOBA: 0.312 vs. Cardinals wOBA: 0.302 — New York's offense generates more value per plate appearance.
  • Yankees FIP: 3.72 vs. Cardinals FIP: 4.14 — New York's pitching staff has been more consistently efficient at preventing runs independent of defense.
  • Yankees ERA: 3.28 vs. Cardinals ERA: 4.14 — The Yankees have actually allowed fewer runs across the season, reinforcing the FIP signal rather than contradicting it.

When elite starting pitching (Schlittler's 2.60 xFIP), a superior team ERA, a better FIP, and a more productive offense all align, the model produces a high-confidence lean. At 73.4%, this qualifies as a strong favourite designation, and the underlying data supports that classification across multiple independent categories.

Injury Report: Key Absences to Monitor

Cardinals Injuries

St. Louis is navigating a crowded injured list heading into this game. Skylar Hales, Travis Honeyman, and Ethan Young are all on the 7-Day IL with undisclosed ailments, while JoJo Romero is sidelined on the 15-Day IL with an abdominal injury. Bullpen and roster depth could be tested if McGreevy labors against a capable Yankees lineup.

Yankees Injuries

New York is not without its own concerns. Cody Bellinger remains on the 10-Day IL with a hamstring injury, Luis Gil is dealing with a shoulder issue on the 7-Day IL, and Luis Garcia is listed as out with an elbow injury. Kaeden Kent and Carlos Lagrange also sit on the 7-Day IL. Despite the depth hits, the Yankees' core statistical advantages remain intact.

Dark Horse Home Run Picks

Nelson Velázquez – Cardinals

Even in a tough matchup against a pitcher posting a 2.60 xFIP, Velázquez has the raw power to catch a mistake pitch and send it over the fence. He is the Cardinals' dark horse to watch for long-ball opportunities on Monday.

Amed Rosario – Yankees

Rosario provides a sneaky power threat in the New York lineup. With the Cardinals sending out McGreevy at a 4.16 xFIP, the conditions are favorable for a dark horse contributor to emerge, and Rosario fits that profile perfectly.

Final Prediction

WP Baseball Predictor Pick: Yankees Moneyline — With a 73.4% win probability, superior pitching from Schlittler, stronger team-wide metrics, and St. Louis managing multiple IL absences, New York is the clear and well-supported choice in this August 3 matchup.
