Cardinals Thrive Despite Struggles in Bullpen Performance

The St. Louis Cardinals are crafting a narrative this season that feels reminiscent of those exhilarating October runs, where teams find a way to win against all odds. With a record of 6-1 in extra innings and a knack for late-inning heroics, their offense has been a beacon of resilience. They thrive on clutch home runs and refuse to back down when the stakes are high. However, relying on such dramatics in the regular season raises a crucial question: can they sustain this success with a struggling bullpen?

As we dive into the 2026 season, the Cardinals’ bullpen has shown only a handful of bright spots amid an overall disappointing performance. While they have managed to outperform expected metrics thanks to solid defensive support from emerging talents like JJ Wetherholt and Masyn Winn, the reality remains stark: their bullpen ranks at the bottom of the league in fWAR. It’s a testament to their ability to win close games, but it’s also a cause for concern going forward.

Is the bullpen’s inefficiency a result of overuse stemming from a lackluster starting rotation? The numbers suggest otherwise. Currently, the Cardinals’ bullpen ranks 20th in innings pitched, and they have accumulated 17 saves, placing them behind only San Diego and Tampa Bay. The real culprit appears to be their troubling strikeout-to-walk ratio, which has seen several pitchers significantly outperform their FIP relative to their ERA.

Ryne Stanek is a prime example of this dichotomy. While he excels at striking out batters, his alarming walk rate of 7.65 BB/9 raises red flags. His fastball has been effective, with a 50% swing-and-miss rate, but his control issues with his slider and splitter—hitting the strike zone just 30% and 22% of the time, respectively—underscore the volatility in his performance. Despite these challenges, he remains a crucial piece of the bullpen puzzle.

On the other hand, Riley O’Brien has emerged as an elite closer, providing a lifeline amidst the bullpen’s struggles. Although he has recently experienced some hiccups in save situations, his overall performance has been crucial, preventing the bullpen from slipping into negative fWAR territory. Behind O’Brien, Gordon Graceffo, JoJo Romero, and Matt Svanson have shared the workload effectively, with manager Oli Marmol demonstrating commendable bullpen management.

Yet, the overarching issue remains the K/BB ratio, which continues to plague the unit. Graceffo, for instance, needs to improve his sinker control, which is currently finding the strike zone just 22% of the time. Similarly, George Soriano’s sweeper has struggled to command the zone, with only 28% accuracy. Meanwhile, Matt Svanson is still working to regain trust after a rocky start, despite his solid fastball velocity.

The silver lining for the Cardinals’ bullpen is their ability to induce ground balls, ranking tied for fifth in the MLB in ground ball percentage. This strength presents an opportunity for pitchers not named O’Brien, Stanek, or Svanson to focus on pitching to contact and leveraging the defense to mitigate their own shortcomings. With fewer walks, the hope is for an increase in groundouts, potentially stabilizing the bullpen as the season progresses.

As the Cardinals navigate the challenges of their pitching staff, the need for improvement is clear. They must address their control issues to avoid being haunted by the specter of dramatic come-from-behind victories that could become a fixture of their season narrative. The upcoming weeks will be critical in determining whether this team can maintain its winning ways amid bullpen struggles.
