2025 Fantasy Outlook
A herniated disc in his back limited Matz to just 44.1 innings in 2024, continuing a dubious streak which has seen him make at least one trip to the injured list in all 10 of his major-league seasons. When healthy, the southpaw managed just a 17.4 percent strikeout rate, which was easily his lowest mark over the last seven campaigns. Matz has produced a 2.43 ERA and 27:9 K:BB over 33 innings out of the bullpen over his three seasons in St. Louis and that might be the best route to keep the left-hander healthy and effective at this point. Fantasy relevance seems unlikely regardless of the role he's in. Read Past Outlooks

Next start undetermined
Cardinals manager Oliver Marmol said Friday that he plans for Matz to pitch out of the bullpen "at the moment," Daniel Guerrero of the St. Louis Post-Dispatch reports.
ANALYSIS
The Cardinals went to a six-man rotation during a stretch of the schedule that was light on off days. However, they are idle for every Thursday in May, allowing them to shift back to a five-man setup for the time being. It sounds like Matz could re-enter the rotation at any point, though, with Marmol saying of Matz's usage that the club can "pick and choose based on how things are going." Matz has pitched well in both roles this season, posting a 1.00 ERA and 11:0 K:BB over nine innings in two starts and a 1.80 ERA and 9:3 K:BB over 15 frames covering seven relief outings.

The general narrative is that Matz's four-year, $44 million contract with the Cardinals was a big blunder, but he quietly began flipping the script last season. The first year of the deal (2022) was definitely a disaster, as he struggled to a 5.25 ERA over only 48 innings (10 starts, five relief appearances) while battling serious shoulder and knee injuries. A lat strain ended his 2023 campaign several weeks early, but Matz had a 3.86 ERA with 98 strikeouts in 105 total innings when healthy. He secured a locked-in rotation spot down the stretch and registered a 1.86 ERA and 38:7 K:BB over his final seven starts. It's difficult to project how this might all translate into the 2024 season, but the 32-year-old southpaw will essentially be free in most fantasy leagues.

Latest Fantasy Rumors

Moving to bullpen
The Cardinals are moving Matz to the bullpen, manager Oli Marmol told Jeff Jones of the Belleville News-Democrat.
ANALYSIS
The move may not be permanent, as Marmol said the move will be "for the time being." Marmol also added that the plan is for Matz to remain stretched out and able to step back into the rotation as needed in the future. Given that Matz has posted a 1.50 ERA with a 1.89 FIP this season, the change clearly isn't performance related. He's pitched both as a starter and reliever in each of his four seasons in St. Louis, so it seems the only reasons behind this move are the upcoming schedule and the fact that Matz has experience bouncing between the bullpen and the rotation.
