The Cardinals added a fresh arm to their rotation this week by signing Dustin May. Derrick Goold of The St. Louis Post-Dispatch reports that the Cards are still interested in adding another starter, but it would likely be more of an innings-eating veteran type to provide stability.
May doesn’t fit the bill of a veteran innings eater. He’s had notable injury problems in his career. From 2019 to 2024, he never topped 56 innings in any individual season and also missed the entirety of the 2024 campaign. He was healthy-ish in 2025, getting to 132 1/3 innings, but finished the season on the injured list due to right elbow neuritis.
The St. Louis rotation is lacking in certainty overall at the moment. Erick Fedde was traded to Atlanta in July. Miles Mikolas became a free agent at season’s end. Sonny Gray was recently traded to the Red Sox. That means they’ve lost three of the five guys who gave them 100 innings or more in 2025.
The other two were Matthew Liberatore and Andre Pallante. Liberatore had a decent 4.21 earned run average in his first full season in the majors. Pallante had a decent first half but then faded and ended the season with a 5.31 ERA.
Michael McGreevy will probably get a rotation spot after he posted a 4.42 ERA in 95 2/3 innings this year but his 14.5% strikeout rate was quite low. Richard Fitts, acquired in the Gray deal, has some okay numbers so far but in just 65 2/3 big league innings. Kyle Leahy may get a rotation audition but he has been a reliever to this point in his big league career. Tink Hence and Brycen Mautz are on the 40-man but haven’t made major league debuts yet. Prospect Quinn Mathews has reached Triple-A but walked 17.5% of batters he faced at that level this year.
Mathews isn’t on the 40-man yet. Of everyone else mentioned, May and Leahy are the only two who can’t be optioned to the minors. As of right now, three spots would probably go to May, Liberatore and Pallante. If they make an external addition, that would leave one spot available for McGreevy, Leahy, Fitts, Hence, Mautz or Mathews. If Leahy doesn’t win a job out of camp, he can be in the bullpen. Anyone else who doesn’t get a job can go to the Triple-A rotation.
This is all theoretical and assuming everyone is healthy. These days, no team makes it through a season with just five starters. Injuries are inevitable and will open up further opportunities for anyone who doesn’t have a rotation spot initially. May is on a one-year deal and will likely be traded this summer if he’s pitching well. The same could be true of whichever veteran is added in the coming months. That would leave more starts for the unproven guys in the final months of the 2026 season.
As for who the Cards add, there are many possibilities. Guys like Jose Quintana, Patrick Corbin, Tyler Anderson, Tomoyuki Sugano, Nick Martinez, Martín Pérez, Andrew Heaney, Michael Lorenzen and many others are free agents.
The trade market has fewer of these types. The Cubs may look to move a back-end guy if they sign a front-end type but intra-divisional trades are always tricky to pull off. The Red Sox may be looking to flip Patrick Sandoval but he’s not exactly stable as he missed all of 2025 recovering from surgery. The Jays may be looking to get out from under the José Berríos deal but the Cards don’t make sense as a landing spot for that contract unless the Jays are willing to give up meaningful prospect talent just to make the deal go away. The Rockies may be willing to trade Kyle Freeland but they need innings themselves.
Time will tell how it pans out but it’s a sensible goal for the Cards. Their offseason to-do list is mostly about subtracting, having already traded Gray and with potential deals for Brendan Donovan, Nolan Arenado, Willson Contreras, Lars Nootbaar, JoJo Romero and others still possible. But they do need to get through the 2026 and have a lot of question marks in their rotation mix. They will want to have chances available for their in-house guys but having a sturdy veteran presence to keep things steady is logical.
