Pittsburgh Pirates
2025 Fantasy Outlook
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. Read Past Outlooks

Struggles early in loss
PPittsburgh Pirates
May 17, 2025
Mlodzinski (1-4) took the loss against the Phillies on Saturday, allowing four runs on seven hits and one walk with two strikeouts over 3.1 innings.
ANALYSIS
The 26-year-old was lifted at 78 pitches with two runners aboard in the fourth inning, both of whom came around to score on a single by Bryson Stott. It marked Mlodzinski's shortest outing of the season and the first time he's allowed more than three earned runs in a start since April 18. He'll take a 5.67 ERA, 1.61 WHIP and 28:12 K:BB across 39.2 innings into a home matchup with the Brewers next weekend.

2023 Fantasy Outlook
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.
