The Marlins have three catchers on their 40-man roster. Barry Jackson of the Miami Herald reports that the club would prefer to open the season with Agustín Ramírez and Liam Hicks in the big leagues, with Joe Mack optioned to Triple-A, though it’s possible Mack could win a job.
Ramírez has shown a lot of promise with the bat but was arguably the worst defensive catcher in the majors last year. In 605 2/3 innings, he was behind the plate for 19 passed balls and 36 wild pitches. In terms of the passed balls, Ramírez lapped the field, with no other backstop allowing more than nine. Four catchers were present for a larger totals of wild pitches but they all had larger samples of playing time.
Modern analytics also agree. Ramírez was credited with minus-14 Defensive Runs Saved last year. The only guy worse was Salvador Perez at minus-15, in a larger sample of innings. Fielding Run Value had Ramirez at -12, worse than everyone except for Edgar Quero. Statcast ranked Ramírez as one of the worst catchers in terms of blocking and controlling the running game, though his framing was well regarded.
It feels inevitable that Ramírez will get moved to designated hitter or first base, where he has spent some time in the minors. The Fish don’t really have a slam-dunk first baseman standing in the way, as they’re going into the season with a hodgepodge group consisting of Hicks, Christopher Morel, Connor Norby, Griffin Conine and Graham Pauley. But the Marlins are apparently not quite ready to make that move. Jackson reports that they still want to give Ramírez a shot to show some improvement behind the plate and potentially stick as a viable backstop.
That could leave Mack trapped at Triple-A for a while longer, even though he feels like the long-term answer behind the plate. The 31st overall pick from the 2021 draft, Mack played 112 games last year, 99 of those at the Triple-A level. His 27.9% strikeout rate at that level was a bit high but he hit 18 home runs and slashed .250/.320/.459 for a 107 wRC+. That’s great production for a catcher, especially one with a strong defensive reputation like Mack. The Marlins added him to their 40-man roster in November to keep him out of the Rule 5 draft.
Going into 2026, Mack is a consensus top 100 prospect, which means the prospect promotion incentive factors in. If the Marlins were to carry him on the roster early enough to get a full year of service time, he could net them an extra draft pick by playing well enough to garner awards consideration. If they don’t call him up that early, he could earn a full year of service retroactively with a top two finish in Rookie of the Year voting.
If Mack ends the 2026 season with a full year of service, he would be on pace for free agency after the 2031 season. If the Marlins hold him down long enough to not get a full year of service and he doesn’t get one retroactively, then that schedule would be pushed into the future by a year.
Turning to the pitching staff, right-hander Janson Junk suffered a right ankle sprain about a week ago and was in a walking boot for a while. It seems he is moving quickly past the issue. Per the MLB.com injury tracker, he was scheduled to throw 15 to 18 pitches off a mound yesterday. There hasn’t been word on him since, so he presumably threw without issue. He posted a 4.17 earned run average for the Marlins in a swing role last year. As of now, he will probably open the season as a long reliever but could earn a rotation job if injuries open a path for him.

55 balls to the backstop in barely 600 innings is almost one per game, that’s terrible. Maybe if framing is de-emphasized in the age of ABS he can focus more on simply catching the ball instead of trying to pull it into the strike zone.
Ramirez has been consistently bad for years defensively, there isn’t going to be any improvement.
You could trot out Greg Maddux and Ramirez would let the ball get away. He is a bad defensive catcher.
Joe Mack is ready for the job and the Marlins could start him opening day but that likely requires a very team friendly extension.
A Freddy Peralta special. 6yr/35M with two 10M team options. If Mack takes a deal like that, he is the starting catcher on opening day. That deal has potential to benefit the Marlins. Joe Mack would be right to take it too. He would have a good opportunity in FA in his age 31 season.
If he doesn’t take a deal like that, he plays the season in AAA and Ramirez works on his game.
A call up in August if the team is in the playoff race is a possibility.
So thankful for modern analytics. Back in the old days they would’ve just kept running Ramirez out there with no clue there was a problem with his catching. Lol.
Um, most fans don’t need the stats to see how bad he is. eyeball test and stats agree on how bad Ramirez’s defense is. So, I’m pretty sure that he would not have been running out there years ago. People knew how bad Mike Piazza’s glove was without the stats. Same thing with Mackey Sasser. Some guys just are very bad with the glove and don’t need anyone to waste time looking at the stats to know it. If anything, a person should feel embarrassed that they see guys like Ramirez, Sasser, Piazza, the Junior Felix’s of the world, Jose Offerman, Oneil Cruz in CF, and still need to go look at stats to figure out they’re bad defensively.
Um,did you see the lol at the end of my comment? Wasn’t meant to be taken this seriously.
It was kind of a vague ‘lol’ as to whether you were knocking people who need to look at stats to figure it out or taking a shot at eyeball test guys.
Marlins are going to carry two catchers, Hicks and Ramirez, and Hicks isn’t much better defensively. He can’t throw anybody out.
As long as Ramirez is hitting the ball, he is likely going to get starts at C for Miami. If Hicks doesn’t hit, he is going to get DFA’d and there is an outside shot that you see Brian Ignoffo get the call before Mack because the Marlins will squeeze him for not taking their rookie deal.
Wait, Yanier Diaz wasn’t the worst defensive catcher?
Mack has a ton of potential and I could be a keystone at a demanding position.
I wish the Marlins would just move Ramirez to DH already and let Hicks and Mack handle the catching duties.
