The St. Louis Cardinals opted to rebuild their roster this offseason by trading away multiple key veterans to land a slew of top prospects. They brought in multiple top pitching prospects, including players like Hunter Dobbins and Richard Fitts.

This season, the Cardinals will lean heavily on their unproven pitchers. They have a lot of talent, but almost none of their starting pitching has proven themselves in the big leagues. This opens the door for some under-the-radar pitchers to burst on the scene.

Thomas Nestico of TJStats recently put together a list of bold predictions with one for each team as the 2026 regular season gets underway. For the Cardinals, Nestico boldly predicted pitcher Kyle Leahy would lead the pitching staff in fWAR, which is a shocking prediction considering how many people believe Matthew Liberatore will take a big step forward this year.

Kyle Leahy has chance to make big leap this year
