Miami Marlins pitching prospect
Adam Mazur tossed five shutout innings on Tuesday en route to earning his first victory of the campaign. He allowed just three hits and a walk. He struck out five batters. This was a nice bounce-back outing for Mazur as he allowed two runs and two hits across five innings in his start of the regular season. The 23-year-old made his MLB debut last summer with the San Diego Padres and held a 7.49 ERA with a 1.81 WHIP across 33 2/3 innings of work. Across this stint, he struggled to control his pitches as he served up 21 free passes. He struggled at the Triple-A level last summer as well, posting a 6.20 ERA with a 1.38 WHIP. Fantasy managers should continue to monitor his progression with Jacksonville, as he could be in the mix to return to the majors later in this summer.

Miami Marlins right-handed pitching prospect
Adam Mazur was sent to Triple-A Jacksonville. The former second-round selection was competing for a spot in the starting rotation, but instead the team will opt to have him continue his development in the minor leagues. Last season, Mazur was dealt to the Marlins at the trade deadline in a package that sent
Tanner Scott to San Diego. During his first 33 2/3 innings in the major leagues, Mazur posted a hefty 7.49 ERA with a 1.81 WHIP. He tallied just 22 punchouts and served up 21 free passes. Last summer in Triple-A, Mazuer logged 61 cumulative innings and posted a 6.20 ERA with a 1.36 WHIP. However, he showed elite command, serving up just 13 walks and tallied 60 punchouts. He should contend for an early return to the majors if he performs well with Triple-A.

Miami Marlins starting pitching prospect
Adam Mazur logged another stellar outing on Wednesday evening. He tossed seven innings of one-run ball with just two hits and no free passes. He struck out a season-high nine batters. This was his second straight quality start and a great sign for the 23-year-old as he posted a hefty 6.92 ERA and a 1.62 WHIP in his previous three outings before this stretch. The Iowa product got a brief look at the major leagues this season when he was still on the Padres and held a 7.49 ERA and a 1.81 WHIP through his first 33 frames. However, since joining the Marlins organization, Mazur has held a much-improved 3.81 ERA and a 0.92 WHIP at Triple-A. The right-hander remains a name to keep an eye on in deeper leagues, as he may earn a late-season promotion to the big leagues.

The Miami Marlins acquired right-handed pitching prospect
Adam Mazur from the San Diego Padres on Tuesday in part of the package that sent left-handed closer
Tanner Scott to the Friars. In addition to Mazur, the Fish landed pitcher
Robby Snelling, infielder
Graham Pauley and second baseman Jay Beshears. Mazur checked in as SD's No. 4 prospect, per MLB Pipeline, and made his first eight major-league starts this year before the trade. The former second-round pick in 2022 out of Iowa has struggled in his first taste of the big leagues, going 1-3 with a 7.49 ERA (6.22 FIP) and 1.81 WHIP with a 22:21 K:BB in 33 2/3 innings. The 23-year-old also got hit around in the hitter-friendly Pacific Coast League before his call-up. It remains to be seen if the Marlins will continue letting him face big-league pitchers the rest of this year, but Mazur could certainly benefit from some more development on the farm.
