How Will The Cardinals Handle Their Rotation Options?

The coming offseason figures to be a tumultuous one for the Cardinals. Coming off a second consecutive season where the club missed the playoffs, St. Louis brass have already announced that significant changes are coming, headlined by Chaim Bloom stepping in to take over baseball operations following the 2025 season (with a larger role in the meantime) and the club planning to slash payroll as they figure to bring back few if any of their departing veteran players.

While Paul Goldschmidt headlines the list of players who appear likely to don another uniform in 2025, what’s not yet clear is what the club intends to do about its starting rotation. Rumors have swirled that the club could shop staff ace Sonny Gray this winter as they look to trim payroll and focus on developing young players, and if Gray were to be moved that would leave only struggling veteran Miles Mikolas, oft-injured swingman Steven Matz, breakout youngster Andre Pallante, and deadline acquisition Erick Fedde as rotation options on guaranteed contracts for 2025. With some interesting young arms such as Michael McGreevey, Sem Robberse, and Adam Kloffenstein in the wings as potential contributors next year, it’s not hard to imagine St. Louis getting solid enough production from its internal options.

With that being said, however, their current rotation picture offers very little certainty, especially should Gray wind up pitching elsewhere next year. After all, even Pallante and Fedde lack track records of success in a big league rotation that go beyond the current season. Fortunately, the Cards have not one but two options available to them that could help raise the floor on their 2025 rotation at a relatively cheap price: Kyle Gibson and Lance Lynn. The veteran hurlers will play at ages 37 and 38 respectively next year, but both posted solid results as back-end rotation options for the club this year and come with identical $12MM club options (with $1MM buyouts) for 2025. Given the club’s focus on the future and desire to trim payroll, it would be something of a surprise if both options were exercised. Given the many similarities between the two veteran Midwest natives, it’s fair to wonder which of the two hurlers would be a better choice for the Cardinals to retain next year, and which one they should send into free agency.

Of the two, retaining Lynn would surely offer a higher ceiling. The veteran hurler pitched the first six seasons of his career in St. Louis as a perfectly capable mid-rotation arm, but had a late-career breakout with the Rangers and White Sox that saw him pitch like a true top-of-the-rotation ace: from 2019 to 2021, Lynn posted a strong 3.26 ERA that was 46% better than league average with a 3.39 FIP and a 27.5% strikeout rate. He also enjoyed slightly better results than Gibson did this year, with advantages in ERA (3.84 vs 4.24), FIP (4.31 vs 4.42), and strikeout rate (21.3% vs 20.9%). For a club that’s likely to rely primarily on internal improvements in order to maintain hopes of contending for a playoff spot in 2025, there’s an argument to be made that Lynn’s ceiling and stronger results this season make him the smarter choice to retain going forward.

That’s not to say there isn’t a case to be made for Gibson, however. While the 12-year MLB veteran has never flashed the ceiling Lynn did during his peak, Gibson is more dependable in some ways. The groundballer rarely misses time due to injury, having made at least 29 starts in nine of his ten full seasons in the majors. By contrast, Lynn was limited to just 21 starts in 2022 and 23 starts this year by knee issues. What’s more, even as Lynn posted stronger overall numbers with the Cardinals this year, certain underlying metrics actually painted a much less clear picture: Gibson’s 4.44 SIERA is nearly identical to Lynn’s 4.40 figure, while Gibson actually wins on both xERA (4.90 vs 4.93) and xFIP (4.19 vs 4.39) thanks in part to a much stronger grounder rate (44.8% vs 36.3%).

While Gibson’s ceiling may not be as high as Lynn’s his reliability could be particularly valuable for a club that figures to rely heavily on young arms who may not yet be ready for a full season’s workload next year, and his comparable expected metrics call into question just how much of an advantage Lynn really has in terms of run prevention. Of course, it’s also worth noting that the club could choose a third option and decline both club options in hopes of finding similar production at a lower cost in free agency. It would be a risky choice to make given the rising costs of pitching in recent years, but a back-end arm like Martin Perez, Jose Urena, or Michael Lorenzen could theoretically be had at a lower price than either veteran’s club option depending on how this winter’s market shakes out. Of course, any player available at that price point would surely have flaws of their own.
