27-Year-Old PitcherSP
Pittsburgh Pirates
2026 Fantasy Outlook
Mlodzinski built up his volume during spring training and was a backend member of the Pirates' rotation on the Opening Day roster. He started in each of his first nine outings of 2025 but was nothing more than a placeholder, eventually moving to a long-relief role out of the bullpen after Mike Burrows was called up from Triple-A. Mlodzinski finished the 2025 season with a 5-8 record with a 3.55 ERA, 1.30 WHIP, three holds and a 102:39 K:BB across 99 innings. Even with Burrows traded to the Astros during the offseason, Mlodzinski figures to reprise his relief role in 2026 given the call ups of Bubba Chandler, Thomas Harrington and Hunter Barco toward the tail end of last season. Mlodzinski's below-average strikeout rate of 21.2 percent is balanced out somewhat by his BB rate (6.4 percent) and GB rate (48.5 percent), and given his projected role out of Pittsburgh's bullpen, that gives him some potential value in leagues that reward holds.

Strikes out eight in no-decision
PPittsburgh Pirates
March 29, 2026
Mlodzinski did not factor into the decision in Sunday's 4-3 extra-inning win over the Mets, allowing two runs on six hits and no walks with eight strikeouts over 4.1 innings.
Analysis
Mlodzinski threw 55 of 85 pitches for strikes and generated just eight whiffs while mostly keeping the Mets in check. The 27-year-old posted a career-high 99 innings last season working as both a starter and reliever, so he likely won't go deep into games often early in 2026. He's slated for a home matchup against the Orioles next weekend.

Past Fantasy Outlooks
2025
2023
Mlodzinski began the 2024 season on the injured list with an elbow injury, but he emerged as one of Pittsburgh's most reliable relievers by season's end. Across his final 35 appearances, he surrendered zero earned runs 27 times and maintained a 2.30 ERA in that span. While it took some time, the Pirates did take note of Mlodzinski's success and pushed him into a high-leverage role in the final two weeks the season, and he delivered two wins and a hold while working exclusively in the seventh and eighth innings. It's dangerous to draw conclusions from such a short sample, but the back end of Pittsburgh's bullpen is uncertain after David Bednar's struggles in 2024, with Mlodzinski a potential option for saves if Bednar's downturn carries over into 2025. The primary problem with considering Mlodzinski as a potential source of saves is that he has a relatively modest strikeout rate (22.2 percent in 86.2 career innings) and is instead reliant on keeping batted balls on the ground to get outs (career 46.7 percent groundball rate). Overall, Mlodzinski is more likely to be relevant in leagues that reward holds, but he's a name to keep on the radar as a potential source of saves.
Mlodzinksi was a competitive balance pick for the Bucs in the 2020 draft, after he saw his draft stock spike due to his performance in the Cape Cod League. Unfortunately, he's found it difficult to stay on the mound, as he struggled to rack up innings both while at South Carolina and in his first season in the pros. That changed in 2022, as he threw 105.1 innings with Double-A Altoona while serving as a starter. He likely has the stuff to stick in that role thanks to a solid, albeit not standout, fastball-changeup-slider mix to turn to. His control doesn't grade out well on most scouting scales around the industry, but Mlodzinski managed a passable 9.4 and 8.7 BB% in his two seasons as a pro. Given the lack of impact arms at the big-league level under team control in Pittsburgh, Mlodzinski will likely get the chance to prove he can be a big-league starter and that journey will almost certainly begin with Triple-A Indianapolis in 2023. If he can stay healthy and show some improved control, he could rise quickly within the Pirates' system.

Latest Fantasy Rumors
Higher-leverage role in 2025?
PPittsburgh Pirates
October 27, 2024
According to John Perrotto of Pittsburgh Baseball Now, Mlodzinski could step into a high-leverage role in 2025.
Analysis
The right-hander has spent most of the past two seasons in the big leagues and has a 2.91 ERA, 1.22 WHIP and 80:37 K:BB over 86.2 frames in his first 86 appearances. David Bednar pitched his way out of the closer role in 2024, and Aroldis Chapman is headed for free agency, which leaves Pittsburgh with some question marks for the ninth inning heading into the offseason. Even if Mlodzinski doesn't end up in the mix for saves, he should see more high-leverage chances in 2025.
