Steven Matz Heads to Tampa on Two-Year Mystery Deal

The first day of the Winter Meetings turns out to have been the calm before the storm, but it did end with a modest bang. Late Monday night, Marc Topkin of the Tampa Bay Times reported that left-hander Steven Matz has agreed to a two-year deal with the Rays. Many details have yet to be reported. The dollar amount is unknown, and it’s not immediately clear whether Matz will slot into the bullpen or the rotation. What is known is that the 34-year-old is coming off an excellent 2025 season, his first as a full-time reliever after 11 years in the majors, and his first without spending a single day on the IL. Matz started the season with the Cardinals before getting dealt to Boston at the deadline. He ran a 3.05 ERA and 3.46 FIP over 53 appearances, including a hot stretch with a 2.08 ERA after the move.
Matz is a sinkerballing left-hander with a career 46% groundball rate. A second-round pick by the Mets in the 2009 draft, he suffered a series of injuries in the minors, including a UCL tear. He debuted in 2015, the last member to debut out of the fearsome youth movement that included Matt Harvey, Jacob deGrom, Zack Wheeler, and Noah Syndergaard. After all that waiting, Matz succeeded immediately, posting a 2.27 ERA over six starts and pitching well in the team’s World Series run. He followed that up in 2016 by going 13-8 with a 3.16 ERA and 3.44 FIP and picking up a Rookie of the Year vote. Unfortunately, the injuries kept coming: back spasm, elbow tightness, shoulder strain, bone spurs, flexor tendon strain, ulnar nerve transposition, finger strain, forearm strain, shoulder impingement. Amazingly, Matz still reached 30 starts twice in his six years with the Mets (and made a full complement of starts in the shortened 2020 season), but he combined for a 4.35 ERA and 4.49 FIP, putting up just 5.1 WAR.
The Mets traded Matz to Toronto in 2021, and he had arguably the most productive season of his career, running a 3.82 ERA and 3.79 FIP over 29 starts and 150 2/3 innings. He parlayed that success into a four-year deal with the Cardinals. His performance was up and down in St. Louis; he continued to deal with injuries and posted ERAs over 5.00 in 2022 and 2024. He put up solid numbers in 2023, but things looked different in 2025. After filling a swingman role in previous seasons, Matz spent the nearly the entire 2025 campaign in the bullpen, where he flourished. (He made two spot starts for St. Louis.) He went more than an inning in 25 out of his 53 appearances, and he was one of just 39 pitchers to throw at least 75 innings and run both an ERA and FIP below 3.50. The Cardinals traded Matz to the Red Sox at the deadline, and he made two more scoreless appearances against the Yankees in the Wild Card Series. Read the rest of this entry »
