2025 Fantasy Outlook
Dealt from San Diego to Miami at the 2024 trade deadline as part of the return for Tanner Scott and Bryan Hoeing, Mazur had a rocky run in his first taste of the big leagues, but there are reasons to expect better from him in 2025. He has some of the best command and control of any starting pitching prospect in the game, pacing all legitimate starting pitching prospects at Triple-A with a 4.9 percent walk rate, and he throws his fastball in the mid-90s. The 6-foot-2 righty throws three secondary offerings, although none of them are plus pitches, and when he's having success it's due to his ability to spot his fastball and then keep hitters off balance when he's ahead in the count. He logged a 1.19 WHIP and 3.92 FIP in 93.1 innings in the minors, with 13 of his 19 starts coming at Triple-A, and he should enter spring training with a chance to win a rotation spot on the stripped down Marlins. Mazur lacks a high ceiling, but he's a better bet to be a useful streamer in 2025 than his putrid MLB numbers from 2024 (7.49 ERA, 1.81 WHIP) suggest. Read Past Outlooks
Signed a one-year contract with the Marlins in March of 2025.
Struggles against Nationals
Mazur (0-3) yielded six runs (four earned) on eight hits and three walks over 4.1 innings Tuesday, striking out one and taking a loss against Washington.
Analysis
Mazur was greeted with a three-run shot by Josh Bell in the first inning. The Marlins then plated a pair of unearned runs in the fourth before Daylen Lile belted a solo homer in the fifth. Mazur had allowed two home runs through three starts at the MLB level this year before Tuesday's poor performance. He's now sporting a 6.30 ERA with a 13:8 K:BB across 20 MLB innings. Mazur is currently projected to face the Tigers at home this weekend, though it's unclear if he'll get another turn in the rotation.

2024 Fantasy Outlook
Mazur checks a lot of boxes dynasty-league managers look for in pitching prospects. He throws a ton of strikes (walk rates below five percent at every stop) and has a full starter's pitch mix. Mazur was a projectable college starter when he was drafted out of Iowa in 2022, as he was 6-foot-2, 180 pounds and had room to put on good weight, and now Mazur's fastball sits at 95 mph. His changeup and slider will each flash plus, and if he continues on his current trajectory, he could surpass even a mid-rotation starter projection. The Padres all of a sudden have some rotation depth, with Jhony Brito and Randy Vasquez waiting for opportunities, but Mazur seems like the most likely of the Padres' Double-A arms to reach the majors this summer.
