9 AM: Marlins RHP Adam Mazur MLB.com’s Christina De Nicola reports today that he will undergo elbow surgery and will miss the entire 2026 season as a result. Mazur wasn’t locked into Miami’s rotation, but he was one of the best depth options in case one of the following got injured. Sandy Alcantara, Yuri Perez, Chris Paddock Or more likely the fourth and fifth starting pitchers. Max Mayer and Braxton Garrett. It’s not yet clear what type of procedure he will need. Mazur recently reported elbow discomfort to the team and was quickly referred for evaluation by renowned surgeon Keith Meister.
Mazur, 24, came to the Marlins with an infielder. graham foleyTop pitching prospects Robbie Snelling and minor league infielder. Jay Beshears Left-hander sent in trade in 2024 tanner scott and right Brian Hoying To the Padres. He’s a 2022 second-rounder who has put up great numbers up to the Double-A level but has run into some trouble at the Triple-A level (5.03 earned run average, 168 1/3 innings) and in more limited Major League action (6.22 earned run average, 63 2/3 innings).
In 2025, Mazur split the season between Triple-A Jacksonville and Miami, pitching 107 1/3 innings with a 4.36 ERA at the former and 30 innings with a 4.80 ERA at the latter. He posted solid strikeout and walk rates in Jacksonville, but had too many home runs to lower his ERA. Home runs weren’t much of a problem in six big league games, but he recorded a career-low strikeout rate of 13.7% in 30 MLB games.
traded Edward Cabrera With the Cubs ryan weathers Against the Yankees, the Marlins entered camp with Alcantara, Perez and free agent Paddack locked in rotation spots. Although both Meyer and Garrett have only pitched four official spring innings, they are both former top-10 picks and top prospects who have previously experienced success in the major leagues.
Garrett had a 3.63 ERA in 247.2 innings in 2022-23, and suffered UCL surgery in 2024 that cost him the entire 2025 season. Meyer has a 5.29 ERA in 25 career starts, but is off to a great start to the 2024 and 2025 seasons. Despite that big start, Miami optioned him in 2024, tying him up for months and leaving Meyer six days short of the service time he needed to become a free agent after the 2028 season instead of the 2029 season. In 2025, a hip injury surfaced and he ultimately had to undergo season-ending surgery.
Depth options on the 40-man roster include a swingman. janson junk (2025 ERA 4.17, 110 innings), Ryan Gusteau (Acquired from the Astros last summer) Jesús Sanchez transaction), Bradley Blaylock (acquired from the Rockies in January) and 2020 2nd round Dax Fulton (Back in shape after suffering multiple injuries, including an internal braces procedure in June 2023). The aforementioned Snelling and fellow left-handers. thomas white There are two most notable rotating arms waiting. Both are top 100 prospects in baseball, but neither needs to be on the 40-man roster just yet. Both are considered nearly MLB-ready, so things will likely change in 2026. White is the more popular of the two, but has slightly less upper-minor experience considering his 2024 draft status compared to Snelling, who is a 2023 draftee.
Mazur will be placed on the major league injured list because he is on the 40-man roster, has big league experience, and was in major league camp at the time of the injury. He will be placed on the 60-day IL if Miami needs additional 40-man roster space. Mazur will accrue one year of service time and have one minor league option year remaining. Miami could control him through arbitration through at least the 2031 season.
