10:17pm: The sides are in agreement on what is believed to be a multi-year deal, reports Jon Heyman of The New York Post.
10:04pm: The Rays are closing in on a deal with free agent left-hander Steven Matz, reports Marc Topkin of The Tampa Bay Times. The deal is still pending a physical.
Matz spent the 2025 season working out of the bullpen. The 11-year big league veteran split the season between the Cardinals and Red Sox. He combined for 76 2/3 innings of 3.05 ERA ball. Matz has a long background as a starter and worked in a swing role with St. Louis as recently as 2024. He could compete for a rotation spot or work multiple innings out of Kevin Cash’s bullpen.
The 34-year-old Matz just wrapped up a four-year, $44MM free agent deal that he’d signed with St. Louis. The signing didn’t really go as the Cardinals planned. Matz had a difficult time staying healthy. He missed most of the 2022 season to a shoulder impingement. A lat strain shelved him in the second half of the following season, and a lower back injury wiped out much of 2024.
Matz combined for just 197 1/3 innings over the first three seasons of that contract. He posted a 4.47 ERA with a slightly below-average 21.9% strikeout percentage. The Cards only gave him a pair of spot starts this year. He still frequently worked into a second inning out of the bullpen but wasn’t tasked with as significant a workload. Matz managed to stay healthy and turned in arguably his best season since 2021.
Over his first 55 innings, the southpaw turned in a 3.44 earned run average while striking out 20.7% of batters faced. The Cards dealt him to Boston at the deadline. His already middling strikeout rate dropped another six points with the Red Sox, though he managed to outperform his peripherals with a 2.08 ERA through 21 2/3 innings. Matz ranked among the bottom 10 relievers (minimum 50 innings) with a 7.8% swinging strike rate. He succeeded with excellent control, issuing walks at a career-low 3.6% clip. He pitched particularly well as a specialist, holding left-handed batters to a .211/.242/.341 batting line in 129 plate appearances.
Tampa Bay has a pair of power lefty relievers in Garrett Cleavinger and Mason Montgomery. Cleavinger is quietly one of the best in the game. Montgomery has the stuff to be an impact arm in his own right, but his control remains a significant question. Montgomery still has a pair of minor league options and can bounce between Tampa Bay and Triple-A Durham. Matz provides a different look as a control specialist but has decent velocity, averaging 94.5 MPH on his sinker.
There’s a decent amount of uncertainty in the rotation behind Drew Rasmussen and Ryan Pepiot. The Rays have Shane McClanahan and Shane Baz lined up for spots. McClanahan will be on an innings limit after consecutive missed seasons. Baz was inconsistent and is at least a theoretical trade candidate. Ian Seymour is probably the in-house favorite to work as the fifth starter, but Tampa Bay is likely to add a veteran innings eater or two.
More to come.
