Cardinals Sign Right-Hander Dustin May in High-Upside Move

The St. Louis Cardinals have made their first notable free-agent move of the Chaim Bloom era, agreeing to a one-year contract with right-handed pitcher Dustin May, pending a physical. The acquisition represents a high-upside addition to the rotation as the club heads into the 2026 season and continues its rebuilding process.

May, 28, was one of the most intriguing free agents available this offseason, attracting attention for his combination of youth, pitch arsenal, and major league experience. He split the 2025 season between the Los Angeles Dodgers and Boston Red Sox, making 25 appearances—including 23 starts—and posting a 7-11 record with a 4.96 ERA over a career-high 132⅓ innings. This marked his first relatively healthy season after a series of injuries had limited his workload in previous years.

Boston acquired May from Los Angeles at the trade deadline in exchange for outfield prospects Zach Ehrhard and James Tibbs III. While expectations were high, May struggled with consistency, posting a 5.40 ERA in six games for the Red Sox before a right elbow neuritis injury in September sidelined him for the remainder of the season, including the postseason. His time with the Dodgers earlier in 2025 saw a 4.85 ERA across 19 starts.

Despite setbacks, May brings a mix of proven performance and potential. Over seven major league seasons, he has battled multiple injuries—including a Tommy John revision, flexor tendon surgery, and a torn esophagus—but has nonetheless demonstrated the ability to dominate when healthy, making him a key high-upside target for a Cardinals rotation seeking depth and talent.

1. Career Overview and Injury History

Dustin May’s career has been a rollercoaster due to injuries but highlights his raw talent and upside. Limited to 324 innings across 71 games in seven seasons, he has nonetheless accumulated 297 strikeouts, a 3.86 career ERA, and a ground-ball rate of 46.6%, showcasing his ability to induce weak contact. May’s major injuries include a Grade 2 UCL sprain and flexor tendon surgery in 2023, followed by a torn esophagus in 2024, and multiple stints on the injured list. Despite these setbacks, he returned in 2025 and threw a career-high 132⅓ innings, signaling durability improvements and potential for future stability. Physically, May has worked to rebuild strength lost during his injury recovery. Standing 6-foot-6, he increased his weight from 185 pounds at the start of 2025 to roughly 205 pounds by season’s end, adding more muscle in the offseason to better sustain his pitching mechanics and velocity. May’s resilience and ability to return from significant injuries make him an intriguing low-risk, high-reward addition for the Cardinals. If he can stay healthy, his skill set could anchor the back end of the rotation and provide innings alongside younger starters like Michael McGreevy and Matthew Liberatore.

2. Pitching Arsenal and Strengths

May’s pitching arsenal is built around a high-velocity fastball mix and a sweeping breaking ball. His sinker, historically reaching the high-90s, averaged 94.5 mph in 2025 as he regained strength, paired with a sweeper featuring elite horizontal movement that breaks in the opposite direction. He also mixes in a four-seam fastball and a cutter, creating a diverse fastball-heavy repertoire. This variety allows May to attack hitters from multiple angles, inducing weak contact and maintaining strikeout potential when healthy. Before his 2021 UCL injury, May’s dominance was evident, posting a 2.93 ERA through his first 31 appearances and playing a key role in the Dodgers’ 2020 World Series championship. His underlying stuff has always made him a frontline starter when healthy, with the potential to return to near-peak performance. With his combination of velocity, movement, and size, May offers the Cardinals a power pitcher capable of anchoring innings, eating deep into games, and complementing a rotation of younger arms as St. Louis looks to reestablish itself in the National League.

3. Role with the Cardinals

For the Cardinals, May fills a key rotation need following the offseason trade of Sonny Gray. He will join a young core of pitchers including Michael McGreevy and Matthew Liberatore, offering experience and innings while giving the team flexibility to develop its rotation moving forward. May’s presence also provides a blueprint for balancing potential with risk. While his health remains a concern, the Cardinals are banking on his ability to stay on the mound and harness his elite stuff over a full season. If successful, he could provide the stability missing from the back end of the rotation in recent seasons. Managerial and coaching staff will likely focus on building May’s endurance while maximizing his strengths. Francona-era philosophies of pitcher development emphasize deep outings, and May’s ability to pitch multiple innings effectively will be central to Cincinnati’s—or in this case, St. Louis’—rotation strategy. Ultimately, the one-year deal allows the Cardinals to evaluate May’s health, effectiveness, and long-term fit, while giving him an opportunity to return to the form that made him one of the league’s most intriguing young pitchers before injuries derailed his trajectory.
