Marlins Name Janson Junk Fifth Starter, Option Braxton Garrett
The Marlins announced Friday that left-hander Braxton Garrett has been optioned to Triple-A Jacksonville. Manager Clayton McCullough confirmed to the team’s beat that righty Janson Junk will open the season as Miami’s fifth starter (via Kevin Barral of Fish On First).
Junk, 30, was always going to make the club’s roster, given last year’s solid showing and his lack of minor league options. The question was whether it’d be in the rotation or in a swing capacity. He pitched 110 innings with a 4.17 ERA, 17.2% strikeout rate, 2.9% walk rate and 40.6% grounder rate in 21 appearances last year (16 starts, five relief outings). That strikeout rate is well below average, but Junk’s walk rate was elite — the lowest among the 127 MLB pitchers who tossed at least 100 frames last year.
This spring, Junk allowed five runs in five official innings but punched out 26% of his opponents against a solid walk rate. Putting him in the rotation affords the Marlins more flexibility with regard to their bullpen composition and also gives Garrett some additional time to round back into form after missing the 2025 season due to injury.
Garrett, 28, was the No. 7 overall pick by the Marlins back in 2016. He never ranked as a top prospect and had done little to make good on that lofty draft status until a breakout showing in 2022-23. Garrett combined for 47 starts (247 2/3 innings) with a 3.63 ERA, 23.8% strikeout rate and 5.1% walk rate across those two seasons, all but solidifying a long-term rotation spot for himself — or so it seemed.
In 2024, Garrett was limited to just seven starts, during which he struggled badly (5.35 ERA). A shoulder impingement and a flexor strain necessitated separate trips to the injured list that season, and his hopes for a 2025 rebound were dashed when he required UCL surgery last spring. Garrett didn’t pitch at all last year and has been built up judiciously thus far. He’s only pitched four official innings in Grapefruit League games, though he’s gotten side work on the back fields.
This is Garrett’s final minor league option year. He’s earning $1.53MM in his second trip through the arbitration process as a Super Two player. As long as he spends even four days on the active roster this year (which seems like a given), he’ll be under club control through the 2028 season.
With Garrett opening the year in Jacksonville, Miami will begin the season with Sandy Alcantara, Eury Perez, Chris Paddack, Max Meyer and Junk in the rotation. Between Garrett’s eventual return and the likely MLB debuts for top prospects Thomas White and Robby Snelling, there could be a fair bit of turnover on that staff this year. If Miami isn’t in contention this summer, both Alcantara and Paddack will stand as natural trade chips if they’re performing well.
Poll: How Will The Marlins Round Out Their Rotation?
While the Marlins enjoyed an encouraging season in 2025 with a 79-83 record that put them on the periphery of playoff race relevance, the club is nonetheless still engaged in a multi-year rebuilding effort. This offseason, that meant trades of controllable rotation pieces in order to bring more young talent into the system. Right-hander Edward Cabrera was dealt to the Cubs for a package headlined by outfielder Owen Caissie, while lefty Ryan Weathers was shipped to the Yankees in return for a package of four prospects. Those departures from the rotation mix would be damaging to any team, but the Marlins are in position to weather the losses thanks to their exceptional pitching depth. Sandy Alcantara and Eury Perez both have ace-level ceilings at the front of the rotation. The Marlins believe Max Meyer is ready to take the step into full-time rotation work after parts of three seasons in the majors, and veteran Chris Paddack was brought in via free agency to eat innings.
That leaves four spots in the rotation accounted for. For much of the offseason the assumption had been that lefty Braxton Garrett would reclaim his spot in the rotation after missing out on the 2025 campaign due to injury. Recent reporting from Christina De Nicola of MLB.com suggests that might not be guaranteed, however. De Nicola writes that the Marlins could consider giving Garrett additional time to rehab and build up towards his return to the majors after last year’s Tommy John surgery. That could involve him beginning the year on the injured list, or even simply using his final remaining option year to send him to the minors. Garrett was incredibly impressive for Miami back in 2023, with a 3.66 ERA in 31 appearances (30 starts) and a solid 23.7% strikeout rate.
Typically, it would be a shock to see the Marlins not simply go back to the once-effective southpaw for the final spot in their rotation. With that said, however, there are some indications that the club is giving a real consideration to Garrett starting the year in the minors. The lefty did struggle a bit in the seven starts he made during the 2024 campaign when he was healthy enough to take the mound, though some grace must be given considering that those starts came with solid peripherals and in the midst of an injury-marred campaign. On the other hand, De Nicola does note that the Marlins are hoping to have Garrett make changes to his approach this year and move into the strike zone a bit more often.
That’s a change that could take some getting used to for the lefty, and simultaneously changing his philosophy as a pitcher while also rehabbing could be a tall order for one Spring Training. If there are questions about Garrett’s ability to take on that workload, starting the season in the minors could make sense. That’s especially true given that Garrett’s return from Tommy John surgery has some similarities to that of Alcantara, who struggled badly upon his return last year. The Marlins are surely hoping to do a better job positioning Garrett for success when he returns than they did with the former Cy Young award winner, and that the lefty will be able to do a lot better this year than Alcantara’s 5.36 ERA in 31 starts last season.
If Garrett were to start the season in the minors, to whom could the Marlins turn? Perhaps the most obvious choice would be right-hander Janson Junk, who served as a swingman for the Marlins last year and posted a solid 4.17 ERA in 110 innings of work (including 16 starts) with even better peripherals. De Nicola notes that manager Clayton McCullough indicated that the club views Junk as a starter, and the team has worked to stretch him out this spring in order to keep him available as an option to start games. With that said, Junk pitched much better as a reliever (2.78 ERA) than as a starter (4.53 ERA) last season and has struggled a bit during camp this spring. Some of that can be attributed to poor sequencing considering Junk’s lackluster 62.2% strand rate in games he started last year, but his strikeout rate dropping from 22.5% in relief to 15.9% when starting games is surely no coincidence.
One other option could be top prospect Robby Snelling. Snelling would be something of a surprise pick for the Marlins, but the former first-rounder and current top-100 prospect is clearly poised to make his big league debut at some point this year. He turned in a dominant year between Double- and Triple-A last year, including 11 starts of 1.27 ERA baseball at the minors’ highest level. He struck out 30.3% of his opponents between both levels, and while he’s struggled in terms of run prevention (7.56 ERA) this spring his 32.5% strikeout rate during camp has been excellent. The Marlins have rarely allowed their young starters to stick in the majors for an entire wire-to-wire big league season during their rookie year, but if the team prefers to slow-play Garrett and keep Junk in a swing role then they might be best served starting Snelling in the majors and sending him down later in the year if he struggles or the rest of the staff is healthy when Garrett is ready.
How do MLBTR readers think the Marlins will ultimately handle the fifth spot in their rotation? Will they stick with Garrett to open the year even in spite of how things went with Alcantara last year? Will they overlook Junk’s lackluster numbers when starting last year and give him a shot? Or will they turn to top prospect Snelling in spite of his mixed performance during camp? Have your say in the poll below:
Who will open the 2026 season in the Marlins' final rotation spot?
-
Braxton Garrett 51% (759)
-
Janson Junk 34% (511)
-
Robby Snelling 15% (225)

Marlins Option Joe Mack, Ryan Gusto
The Marlins announced their latest round of camp cuts this morning, and the most notable among that group were the decisions to option top catching prospect Joe Mack and right-hander Ryan Gusto to the minor leagues.
Mack, 23, is a consensus top-100 prospect and a first rounder from Miami’s 2021 draft class. After setting Double-A on fire for 13 games to open the year last season, Mack was promoted to Triple-A and hit a solid .250/.320/.459 with 18 homers, 18 doubles, and 2 triples in 100 games at the level. That was good for a 107 wRC+ at the level, which isn’t quite up to par for the typical top prospect but is nonetheless impressive considering his age and position. A 27.9% strikeout rate at Triple-A last year exacerbates concerns from scouts about Mack’s contact abilities, but the overall package is undoubtedly impressive.
Those questions are perhaps why it was reported last month that, while Mack would get the opportunity to fight his way onto the MLB roster, the team’s preference was for him to begin the season at Triple-A and hand catching duties over to the combination of Liam Hicks and Agustin Ramirez. Hicks was a pick in the 2024 Rule 5 draft who enjoyed a solid rookie season for the Marlins last year. He turned in a 98 wRC+ in 119 games behind the plate, though lackluster defensive metrics left him to be worth just 1.0 fWAR and 1.3 bWAR. Ramirez was also a rookie last year, and was the prize of the team’s Jazz Chisholm Jr. trade with the Yankees at the 2024 trade deadline. Ramirez slugged 21 homers in 136 games but got on base at just a .287 clip, leaving him with a 91 wRC+. He split time between catcher, first base, and DH in his first year as a big leaguer without showing strong defense at any of those positions.
There’s little doubt that Mack will be the long-term answer for the Marlins behind the plate as long as he hits at an even close to league average clip. He’s a well-regarded defender behind the plate who has been lauded for his strong arm and is far and a way the best defender of the team’s three young catchers according to scouts. With that being said, Mack is still young enough with enough questions about his hitting that it’s somewhat understandable that the Marlins would be interested in giving him more time to develop in the minor leagues. That’s all the more true after a tough spring at the plate, where he went just 3-for-24 with seven strikeouts. There’s little doubt that Mack will make his MLB debut at some point this year so long as he stays healthy, but in the meantime Christina De Nicola of MLB.com writes that the Marlins are encouraging him to work on his approach at the plate and spend more time getting familiar with the ABS strike zone while he waits for that opportunity at Triple-A.
As for Gusto, the right-hander was a key piece of the return for Jesus Sanchez at last year’s trade deadline. Gusto made his big league debut with the Astros just last year and was a solid swing man for Houston, posting a 4.92 ERA with a 4.16 FIP in 86 innings split between ten starts and 14 relief appearances. After being dealt to the Marlins, however, Gusto struggled badly. He made three starts in Miami and allowed 17 runs on 19 hits (including four home runs) and walked (8) nearly as many batters as he struck out (10), ending with a 9.77 ERA in 15 2/3 innings of work. He struggled just as badly at Triple-A, and while he looked a bit better this spring he’s still ultimately squeezed out of a crowded Marlins rotation and better serves the Marlins as stretched-out depth than converting to a short relief role in the bullpen.
Which Top Prospects Could Be On 2026 Opening Day Rosters?
In the not-too-distant past, it was relatively rare for organizations to break camp with their very best prospects on the roster. It still happened at times, but MLB's service time structure was set up such that keeping a top prospect in the minors for even two weeks to begin the season effectively ensured that he'd be controllable for seven years rather than the standard six. There were obvious exceptions to this thinking -- Atlanta fans surely remember Jason Heyward breaking camp as a 20-year-old and belting a three-run homer on Opening Day -- but there were far more cases of keeping a player in the minors to buy the extra year. Kris Bryant, Vladimir Guerrero Jr., George Springer and others were all called to the majors just when they'd spent enough time in the minors to give their clubs an extra year of control. There was nothing inherently nefarious about the gambit; teams were operating within the collectively bargained rules and making business decisions.
The 2022-26 collective bargaining agreement sought to implement some real incentives for teams to bring their best players north to begin the season, however, and by and large they've been effective. With the Prospect Promotion Incentives (PPI), any prospect who appears on two recognized top-100 lists and is called up early enough to earn a full service year can net his team a bonus draft pick, either in that season's Rookie of the Year voting or in MVP/Cy Young voting over the next three seasons.
There's also a disincentive to holding a player down. For those same qualified top prospects, a top-two finish in either league's Rookie of the Year voting will net a full year of major league service time, regardless of when they were called up. Said prospects still have around 90% of a season in such instances, which is more than enough time to turn in a ROY-worthy performance.
Teams now know that holding a player down for 15 days or so might lead to him getting a full year of service anyhow and comes with the disadvantage of rendering that player ineligible for future PPI picks. As such, it's become increasingly common for touted prospects to break camp on their teams' rosters.
With that in mind, and with fewer than two weeks to go until Opening Day, it seems worth running through a slate of top prospects who could factor into their teams' Opening Day plans.

Marlins’ Adam Mazur Undergoes UCL Surgery
12:05pm: Mazur underwent a UCL reconstruction (Tommy John surgery) and had an internal brace installed, reports De Nicola. The estimated timetable for his return from that hybrid procedure is 13 to 14 months.
9:00am: Marlins righty Adam Mazur will undergo elbow surgery today and miss the entire 2026 season as a result, MLB.com’s Christina De Nicola reports. Mazur wasn’t locked into Miami’s rotation but was among the top depth options in the event of an injury to one of Sandy Alcantara, Eury Pérez, Chris Paddack or likely fourth and fifth starters Max Meyer and Braxton Garrett. It’s not yet clear which type of procedure he’ll require. Mazur recently reported elbow discomfort to the team and was quickly sent for an evaluation with renowned surgeon Keith Meister.
Mazur, 24, came to the Marlins alongside infielder Graham Pauley, top pitching prospect Robby Snelling and minor league infielder Jay Beshears in the 2024 trade that sent lefty Tanner Scott and righty Bryan Hoeing to the Padres. He’s a 2022 second-rounder who posted big numbers up through the Double-A level but has run into some trouble at both the Triple-A level (5.03 ERA, 168 1/3 innings) and in more limited major league work (6.22 ERA, 63 2/3 innings).
In 2025, Mazur split the season between Triple-A Jacksonville and Miami, tossing 107 1/3 innings with a 4.36 ERA at the former and 30 innings with a 4.80 ERA with the latter. He turned in solid strikeout and walk rates in Jacksonville but was far too homer-prone to keep his ERA down. Homers were less of an issue in his six big league starts, but he recorded a bottom-of-the-barrel 13.7% strikeout rate in his 30 MLB frames.
Having traded Edward Cabrera to the Cubs and Ryan Weathers to the Yankees, the Marlins entered camp with Alcantara, Pérez and free agent signee Paddack locked into rotation spots. Meyer and Garrett have both pitched only four official spring innings, but they’re both former top-10 picks and top prospects who have experienced success in the majors previously.
Garrett notched a 3.63 ERA in 247 2/3 innings from 2022-23 before a 2024 UCL surgery wiped out his entire 2025 season. Meyer has a 5.29 ERA in 25 career starts but has had big starts to his season in both 2024 and 2025. Miami optioned him in 2024 despite that big start, keeping him down for months and leaving Meyer six days shy of the service time he’d have needed to be a free agent following the 2028 season instead of the 2029 season. In 2025, a hip injury surfaced and eventually required season-ending surgery.
Depth options on the 40-man roster include swingman Janson Junk (4.17 ERA, 110 innings in 2025), Ryan Gusto (acquired from the Astros in last summer’s Jesús Sánchez trade), Bradley Blalock (acquired from the Rockies in January) and 2020 second-rounder Dax Fulton (healthy again after multiple injuries, including a June 2023 internal brace procedure). The aforementioned Snelling and fellow left-hander Thomas White are the two most notable rotation arms in waiting; both rank among baseball’s top 100 prospects, but neither has needed to be added to the 40-man roster just yet. That’ll very likely change in ’26, as both are considered nearly MLB-ready. White is the more touted of the two but has a bit less experience in the upper minors, given his status as a 2024 draftee compared to Snelling, a 2023 draftee.
Since Mazur is on the 40-man roster, has big league experience and was in major league camp at the time of injury, he’ll be placed on the major league injured list. If and when Miami needs an additional 40-man roster spot, he’ll be placed on the 60-day IL. Mazur will accrue a full year of service time and retain the lone minor league option year he has remaining. Miami will be able to control him via arbitration through at least the 2031 season.
NL East Notes: Wentz, Fulton, Miller
Joey Wentz and the Braves may have gotten relatively lucky after the left-hander was carted off the field with an apparent right leg injury during today’s game with the Rays. According to MLB.com’s Mark Bowman, Wentz will undergo tests to determine the extent of the injury, but initial examinations indicate that Wentz likely isn’t dealing with anything too serious. Wentz hurt himself while covering first base on a bunt attempt in the fifth inning, and the cart ride may have been precautionary, as he was able to get to and from the cart without assistance or any overt discomfort.
While it seems like Wentz may be okay, his situation naturally drew concern given how Atlanta’s rotation depth has already been tested this spring. Spencer Schwellenbach and Hurston Waldrep each underwent surgery in February to remove loose bodies from their elbows, leaving both starters on the injured list for at least (and in a best-case scenario) the first two months of the regular season. These injuries created an opportunity for Wentz and other depth starters to compete for the fifth spot in the Braves’ rotation, and Wentz has helped his bid with a 3.18 ERA over 5 2/3 innings of Grapefruit League action. If this leg problem ends up sidelining Wentz for any decent amount of time, it could open the door for Bryce Elder or non-roster invite Martin Perez as the fifth starter.
More from around the NL East…
- Left-hander Dax Fulton was one of five players optioned to the Marlins‘ minor league camp today, though “he’s much closer than he was to be able to come up and really help us” in the majors, manager Clayton McCullough told MLB.com’s Christina De Nicola and other reporters. McCullough implied that Fulton could be called up to pitch out of Miami’s bullpen during the regular season, though the southpaw will continue to be stretched out as a starting pitcher in Spring Training. A second-round pick for Miami in the 2020 draft, Fulton was a well-regarded prospect before a UCL surgery cost him most of the 2023 season and the entirety of the 2025 campaign. Fulton returned to action in 2025 and posted a 5.38 ERA over 103 2/3 combined innings with the Marlins’ Double-A and Triple-A affiliates, starting 22 of his 23 games. While the Marlins don’t want to close the door on Fulton’s rotation potential at age 24, allowing him to make his Major League debut as a reliever would perhaps help ease Fulton’s transition to the Show.
- Phillies top prospect Aidan Miller is still battling lower-back problems, and seems like a candidate to begin the season on the Triple-A injured list. Miller played through a similar injury at the end of the 2025 minor league season, and the back issue has kept him off the field this spring. Despite the lingering nature of Miller’s bad back and the fact that the prospect visited the Phillies’ medical staff in Philadelphia on Friday, manager Rob Thomson told The Athletic’s Charlotte Varnes and other reporters that the team isn’t too concerned about the injury, even though “we don’t have a timeline” as to when Miller might get back on the field. “I mean, he hasn’t swung a bat in two weeks. So, we just want to get him healthy, where there’s no pain, and get him back playing again,” Thomson said. A consensus pick as one of baseball’s top position-player prospects, Miller needs a bit more minor league seasoning (he played in just eight Triple-A games in 2025) but is expected to make his MLB debut at some point in 2026, with an eye towards a starting role in the Phillies’ infield by 2027.
Adam Mazur To See Specialist For Elbow Discomfort
Marlins right-hander Adam Mazur is going to see renowned surgeon Dr. Keith Meister about some elbow discomfort, per Christina De Nicola of MLB.com. He has already had some imaging done, per Craig Mish of SportsGrid.
At this point, there aren’t many details, but it’s always a bit ominous when concerns arise with a pitcher’s elbow. Mazur was acquired from the Padres at the 2024 deadline in the deal headlined by Tanner Scott. He served as optionable rotation depth for Miami last year, making six big league starts with a 4.80 earned run average and 13.7% strikeout rate. In 22 Triple-A appearances, he had a 4.36 ERA and a much more encouraging 22.2% strikeout rate.
He was likely going to start 2026 in a similar role. He still has one option season remaining and wasn’t likely to be one of the top five starters to begin the season. Even though the Marlins traded away Edward Cabrera and Ryan Weathers this winter, they still project to go into the year with a rotation featuring Sandy Alcantara, Eury Pérez, Chris Paddack, Max Meyer and Braxton Garrett. They also have Janson Junk in the mix. He is out of options and should be on the big league roster somewhere, perhaps in a long relief role if there’s no room in the rotation.
Pitching injuries are inevitable and a team will need far more than just five or six starters to get through a season. The Marlins had 15 different guys make at least one start last year, for instance. Mazur was once of 11 guys to make at least three starts.
The depth has been challenged a bit here during spring training. Junk had an ankle sprain a couple of weeks ago but he seemed to be fine now. Per De Nicola, he is scheduled to make his Grapefruit League debut tomorrow. Prospect Thomas White recently suffered an oblique strain and will be sidelined for three to four weeks.
The Fish have Dax Fulton, Bradley Blalock and Ryan Gusto as optionable starters currently on the 40-man. Prospect Robby Snelling has 11 Triple-A starts under his belt and should push for a major league debut in 2026. If Mazur needs to miss some time, it would increase the likelihood of the Marlins turning to those other arms.

Thomas White Suffers Oblique Strain
Left-handed pitching prospect Thomas White is dealing with a grade one strain of his right oblique that will preclude him from appearing in further Spring Training games, according to a report from Christina De Nicola of MLB.com. Louis Addeo-Weiss of Fish On First added that, according to manager Clayton McCullough, White felt some discomfort during his spring debut and is facing a three to four week timeline before he can return to the mound.
It’s a disappointing setback for the 21-year-old, who was a first-round pick by the Marlins in the 2023 draft and in the years since then has risen to become one of the very best pitching prospects in the entire sport. After a strong season in the lower minors in 2024, White impressed in a big way across 21 starts during the 2025 campaign. He pitched well at High-A to open the season and quickly earned a promotion to Double-A, where he was utterly dominant with a 1.59 ERA in 45 1/3 innings of work across ten starts. He struck out a sensational 39.3% of his opponents against a 12.6% walk rate, leaving him with elite peripherals (2.24 FIP, 2.54 xFIP) to go with his impressive run prevention numbers.
That performance at Double-A earned White a brief look at Triple-A near the end of the season as well as an invite to big league camp this spring. White struggled in his spring debut, as he surrendered two runs on two hits and a walk while striking out just one in his lone inning of work. That performance was surely hampered by the oblique strain he’s now known to have been dealing with during that outing, and he’ll spend the rest of Spring Training focused on rehabbing that issue in hopes of being healthy not long after minor league games begin. While White was in camp with the Marlins, he never had an especially strong chance of cracking the Opening Day roster given that Sandy Alcantara, Eury Perez, Max Meyer, Braxton Garrett, Chris Paddack, and Janson Junk at minimum are each ahead of him on the depth chart on the moment.
That will surely change at some point this season, provided White can stay healthy and build on last season. His two starts at Triple-A last year were a mixed bag; while he struck out an absurd 42.5% of his opponents at the level, he also walked an untenable 25%. Significant conclusions can’t be drawn from a sample size of less than two innings, of course, but White walked 13.6% of his opponents overall in the minors last year and will surely need to tighten up his control at least somewhat before he can break into the majors and fulfill his promise as a potential future front-of-the-rotation arm for the Marlins.
Throughout the season, White figures to be joined in the Triple-A rotation by fellow top prospect Robby Snelling, who split last year between Double- and Triple-A and also figures to be on the big league radar at some point this year. White and Snelling currently looked blocked in Miami at least on paper, but offseason trades of Edward Cabrera and Ryan Weathers helped to clear the deck for them somewhat, and the checkered injury histories of Garrett, Perez, and even Alcantara suggest that innings should be available for them once they’re ready to take the next step into the majors.
Marlins Notes: Stowers, Arquette, Pauley
The Marlins had a bit of an injury scare regarding star outfielder Kyle Stowers today, as he was scratched from his scheduled appearance in the Miami lineup today due to hamstring tightness. As noted by Christina De Nicola of MLB.com, manager Clayton McCullough told reporters this afternoon that imaging on Stowers had revealed a “very minor” strain in his right hamstring.
While hamstring strains can often be serious issues, with even relatively minor strains costing players upwards of a month, it seems Stowers’s strain was caught early enough that it shouldn’t be a major problem for him. McCullough indicated that Stowers will be sidelined for just a week or two before returning to game action, and that he could resume taking at-bats outside of games within the next few days. That’s great news for the Marlins given that Stowers is their best and most established hitter on the roster at the moment. The 2025 All Star is coming off a rookie campaign where he slashed an excellent .288/.368/.544 with 25 homers and 21 doubles in 117 games.
If the Marlins are going to build on their third-place finish in the NL East last year and push back over .500 for the first time since their surprise postseason appearance back in 2023, they’ll need Stowers to be healthy and firing on all cylinders. With Opening Day now just a month away, it would be understandable for Miami to be cautious with Stowers as they bring him back into game action over the coming weeks. If Stowers suffers a setback or his hamstring is re-aggravated once he begins ramping back up, that could put his availability for the start of the season in danger. Youngsters Jakob Marsee and Owen Caissie currently figure to handle center field and right field for the Marlins, respectively, but a more serious injury to Stowers could open the door for some combination of Griffin Conine, Javier Sanoja, Christopher Morel, and Esteury Ruiz to get looks in his absence.
Looking elsewhere on the Marlins’ roster, De Nicola also reports that top Marlins prospect Aiva Arquette underwent core muscle surgery recently and is facing a four to six week recovery period before he can resume baseball activities. Arquette reportedly suffered a left groin strain during his offseason workouts, and while he stopped activities and focused on recovery from there his arrival in camp came with renewed discomfort and prompted the procedure. A consensus top-50 prospect in the sport, Arquette was Miami’s first-round pick (seventh overall) in the 2025 draft. He scuffled a bit in his first 27 games as a professional last year at the High-A level, but the 22-year-old figures to spend much of the year at Double-A once he’s ready to return to action and could be on the radar for a big league debut sometime next year.
Elsewhere on the infield, MLB.com notes that Graham Pauley has begun working his way back after being shut down due to forearm tightness earlier this week. Pauley is slated to throw to 90 feet and take live at-bats today, and is slated to serve as the team’s DH in tomorrow’s Spring Training game against the Nationals. Assuming those first steps go well, it stands to reason that Pauley could be back to regular work at some point next week. Pauley hit just .224/.311/.366 in 64 games for the Marlins last year, but his left-handed bat and solid defense at third base could still earn him some work around the infield against tough right-handed pitchers throughout the year given that switch hitter Xavier Edwards is the only other infielder on the projected roster that doesn’t bat right handed.
Marlins Notes: Mack, Ramírez, Junk
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.
