The St. Louis Cardinals could enter the 2027 offseason with a surprisingly unusual problem: they may not need to spend heavily on starting pitching. While fans naturally want the front office to pursue another established arm after years of rotation uncertainty, the organization appears to have enough internal options to take a more patient approach. Rather than immediately searching for another expensive veteran or reclamation project, the Cardinals could decide to give their young pitchers a genuine opportunity to establish themselves at the major-league level.
That approach would represent a significant change in philosophy for St. Louis, particularly after the club benefited from taking a chance on Dustin May in 2026. May represented the type of low-cost upside play that could have justified another rotation addition, but the Cardinals now have considerably more depth behind their projected starters. Chaim Bloom’s end-of-season comments suggest the organization wants to continue evaluating its developing pitchers before making major commitments. After repeatedly emphasizing player development, the Cardinals have reached a point where adding another starter could potentially block players they have spent considerable time and resources developing.
The five pitchers who finished the 2026 season in the rotation — Andre Pallante, Michael McGreevy, Kyle Leahy, Quinn Mathews and Matthew Liberatore — are not an intimidating group on paper compared with rotations built around elite aces. However, the picture becomes much more encouraging when their individual performances and remaining upside are considered. Pallante, for example, enjoyed a major bounce-back season and once again demonstrated why the Cardinals value his ability to generate ground balls and consistently provide innings. He finished 2026 with a 3.83 ERA across 162 innings and produced 2.7 fWAR. He may never be viewed as a traditional No. 1 starter, but his ability to eat innings at an affordable cost gives St. Louis considerable value.
McGreevy is another pitcher who could benefit from being given additional time rather than being immediately replaced. His 3.95 ERA was encouraging, although some of his underlying numbers indicate that regression could become an issue. His performance against left-handed hitters was particularly encouraging because his changeup emerged as an effective weapon. At the same time, his second-half numbers showed why the Cardinals cannot simply assume he has already solved the starting role. His ERA climbed significantly after the All-Star break, while opposing hitters became considerably more productive against him. Still, a pre-arbitration pitcher capable of handling a significant workload provides the Cardinals with an inexpensive option worth developing.
Leahy might actually be the most intriguing member of the group. His overall season may not immediately grab national attention, but his performance during the heart of the season provides a compelling reason for the Cardinals to remain patient. From May through August, Leahy threw exactly 100 innings and posted a 2.43 ERA with a 2.99 FIP. Those numbers suggest there is considerably more upside than his overall statistics might indicate. If he can sustain something close to that level over a larger workload in 2027, St. Louis could suddenly have another legitimate mid-rotation starter without spending millions on the free-agent market. His 2.6 fWAR further strengthens the argument that the Cardinals should see what they have before looking elsewhere.
Then there is Mathews, arguably the pitcher who gives Cardinals fans the most reason for optimism. His September performance provided a glimpse of what a full season could look like. Mathews posted a 3.03 ERA over 29.2 innings while striking out 26 hitters and limiting opponents to a .234/.308/.393 slash line. More importantly, his late-season improvement came at a time when the Cardinals needed young pitchers to demonstrate that they could handle the major-league environment. Rather than viewing Mathews as a temporary option, St. Louis should enter 2027 with the expectation that he can compete for a meaningful role in the rotation.
Liberatore is the obvious exception. His 155 innings and 5.23 ERA were difficult to overlook, and his problems during poor innings continued to raise questions about whether he can consistently succeed as a starter. His 4.62 FIP indicates that some of the damage may have been influenced by bad luck, but that does not eliminate the larger concerns. His fastball performance remains particularly troubling, and another disappointing season could finally force the Cardinals to reconsider his long-term role. Still, Liberatore could enter spring training stretched out as a starter, allowing the organization to preserve him as rotation depth while also considering whether his future might ultimately be in the bullpen.
The biggest reason for avoiding an aggressive rotation move, however, is the depth developing behind those five pitchers. St. Louis finished the year with several intriguing arms at Triple-A, including Cooper Hjerpe, Richard Fitts, Tekoah Roby, Jurrangelo Cintje and Mason Molina. Their development gives the Cardinals something they have lacked in recent seasons: multiple legitimate internal alternatives. Instead of being forced to rush a young pitcher into the majors because there are no other options, the Cardinals can now allow these arms to develop at their own pace while still knowing that reinforcements could emerge during the season.
The next wave could be even more interesting. Liam Doyle, Tanner Franklin, Daniel Eagan, Yhoiker Fajardo and recently claimed Chase Hampton could potentially enter the major-league picture as the 2027 season progresses. That does not mean all of them will become successful starters, but having that many developing options dramatically changes the organization’s risk calculation. If one or two break through, St. Louis could have a much deeper rotation without spending significant money in free agency.
That financial flexibility could ultimately be more important than adding another starter. Instead of committing a large contract to a pitcher who may only provide modest value, Bloom could direct resources toward other areas of the roster, improve the bullpen, strengthen the infield or extend players the organization believes belong to its long-term core. The Cardinals still have plenty of work to do, but spending simply for the sake of making a splash would not necessarily solve their biggest problems.
There is also a strategic advantage to waiting. If the current rotation performs well, the Cardinals will have saved money while giving their young pitchers valuable experience. If the rotation struggles, the front office can address the problem during the season when it has more information about which prospects are ready and which areas actually require reinforcement. That gives Bloom greater flexibility than making an expensive commitment before the season even begins.
For Cardinals fans, this may not be the most exciting offseason scenario. Many supporters understandably want the organization to demonstrate that it is serious about competing by adding established talent. But the smartest move may not always be the most headline-grabbing one. St. Louis appears to have finally reached a point where its pitching pipeline can provide legitimate depth, and blocking that development with another expensive addition could be counterproductive.
The 2027 rotation may not enter spring training looking like one of baseball’s best, but it could be deeper, younger and considerably more flexible than it appears on paper. Pallante, McGreevy, Leahy and Mathews each offer different reasons for optimism, while Liberatore remains a potential depth piece and several highly regarded prospects are waiting behind them. Unless the Cardinals find a veteran pitcher who offers exceptional value, patience could be the better strategy.
For Bloom and the Cardinals, the challenge will be resisting the temptation to make a move simply to satisfy outside expectations. The organization has spent years building its next generation of pitching, and 2027 could be the season when St. Louis finally finds out how much that development is worth. Instead of asking, “Which starter should the Cardinals buy?” the more important question may be whether they should allow their own pitchers to answer the rotation problem first.
