Diamondbacks vs. Cardinals Pitching Matchup
Mitch Bratt is scheduled to make his major league debut for Arizona. Since he has not appeared during the 2026 season, there are currently no statistics available. His first outing will be one of the biggest storylines entering tonight’s game.
Many eyes will be on the rookie left-hander.
Debut starts often bring unpredictability and excitement. Arizona will be hoping Bratt can provide a steady performance right away.
Matthew Liberatore gets the start for St. Louis carrying a 3-4 record this season. He owns a 5.23 ERA and has recorded 67 strikeouts. The left-hander has shown the ability to miss bats despite some uneven results.
His WHIP currently stands at 1.56.
That figure reflects ongoing challenges with allowing baserunners. Liberatore will be looking to improve both his ERA and WHIP as the season continues.
Arizona Diamondbacks vs. St. Louis Cardinals bottom line: A tightly contested series continues with Arizona relying on a debut starter and St. Louis looking for more consistency from Liberatore.

Diamondbacks Cardinals Free Pick: Under 9
Here is my Diamondbacks Cardinals free pick: The recent series history points toward a lower-scoring game, with the under cashing in the last 2 meetings between these teams.
Neither offense has been lighting up scoreboards on a consistent basis.
St. Louis owns a slight edge on the mound, and that could matter in what projects to be a fairly even matchup. The Cardinals have been getting enough pitching to stay competitive most nights.
Arizona has had its share of offensive ups and downs lately as well. When these teams get together, runs have generally been harder to come by than expected.
The recent trends continue to favor a lower total.
This feels like another game where pitching stays in control.
Cardinals-Diamondbacks Under 9 is where I land.
