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.

Injury Notes: Simpson, Freeman, Junk, Pereira
Outfielder Chandler Simpson is experiencing left hamstring tightness in early camp, according to Marc Topkin of the Tampa Bay Times. The Rays will keep him out of the first few exhibition games to allow him time to rest. “Right now, we’re going to slow play him, just get his legs underneath him,” said manager Kevin Cash on Friday. Cash went on to emphasize the value of Simpson’s speed and the importance of getting him back to 100% rather than risk further injury.
Indeed, Simpson is one of the fastest players in the game. His 29.6 MPH sprint speed ranked in the 97th percentile according to Statcast. Meanwhile, his 44 stolen bases in 2025 tied with the Guardians’ Jose Ramirez for second in the majors, with Simpson achieving that in 49 fewer games. That said, while he has value as a speed and contact guy, he’s also limited by on-base and defensive issues. His outfield glovework was viewed negatively by Defensive Runs Saved (-9) and Outs Above Average (-5) in 2025. Continued hamstring issues might hamper his defense even more, so it makes sense for the Rays to ease him into game action.
A few other injury updates around the game:
- Rangers infielder Cody Freeman will be out for 4-6 weeks with a lower back fracture, according to manager Skip Schumaker (link via Shawn McFarland of Dallas Morning News). Freeman felt some discomfort a few days ago that lingered into yesterday, at which point scans revealed the fracture. The 25-year-old made his big-league debut last year, though his line of .228/.258/.342 in 121 plate appearances was underwhelming. He did much better at Triple-A, grading out 31% better than average by wRC+. Freeman was set to compete for an Opening Day roster spot but will now be out until late March at best. He’ll be re-evaluated at that point and will obviously need time to ramp up, so he won’t be ready for Opening Day.
- Marlins right-hander Janson Junk rolled his ankle in team workouts earlier this week. He was diagnosed with a Grade 1 sprain after undergoing testing, though he is now out of his walking boot and playing catch (video from Christina De Nicola of MLB.com). For his part, Junk said on Thursday that he doesn’t expect to miss multiple weeks. The 30-year-old impressed in a swingman role last year, accruing 2.5 fWAR in 110 innings thanks to his sweeper (+8 run value according to Statcast) and a microscopic 2.9% walk rate. He had been building up as a starter thus far. Manager Clayton McCullough confirmed that is still the case and that the team will “just see how this setback… affects what he can end up getting to by the end of camp” (link via De Nicola).
- White Sox outfielder Everson Pereira is currently day-to-day with right side tightness, per James Fegan of Sox Machine. The 24-year-old was acquired in a four-player trade with the Rays in November which saw the team part with a solid reliever in Steven Wilson. On that basis, the team was expected to carry the out-of-options Pereira on the roster as a backup outfielder. That may still be the case since Pereira is merely day-to-day and hasn’t been placed on the injured list. Luisangel Acuña is also on hand, though he will split time between the infield and outfield and shouldn’t affect Pereira’s roster spot if the latter is healthy by the end of camp.

Marlins Notes: Stowers, Caissie, Junk
The Marlins and breakout right fielder Kyle Stowers discussed a long-term contract earlier in the winter, and while no deal came together, the 28-year-old slugger told the Marlins beat in camp yesterday that he remains open to a deal (video link via MLB.com’s Christina De Nicola). Stowers pushed back on reports that suggested he’d had a nine-figure asking price, plainly stating, “I didn’t ask for $100MM” and adding that he was never presented a formal offer from the club.
“I’m just so excited to be here,” said Stowers. “So grateful to be in this organization. I was bummed we didn’t get something figured out — would love to some day — but at the same time, let’s take care of this year, and we’ll go from there. … I can’t stress enough how much I love this organization, how much I love being in Miami and playing for this team, [with] this group of guys.”
A well-regarded prospect who came to Miami alongside Connor Norby in the deal sending Trevor Rogers to Baltimore, Stowers broke out with a career-best .288/.368/.544 batting line (149 wRC+) and 25 home runs in only 457 plate appearances last year. He’d very likely have topped 30 home runs and perhaps even garnered some down-ballot MVP votes had an oblique strain not shelved him for about six weeks and limited him to 117 games.
Stowers struggled against lefties, hitting only one of his 24 round-trippers against a southpaw, and he’s probably not going to maintain a .356 average on balls in play. That, coupled with his 27.4% strikeout rate, might lead to some regression in his rate stats. But even if Stowers doesn’t hit for a particularly high average, his 10.5% walk rate and strong batted-ball metrics suggest he ought to be able to post a quality on-base percentage with plus power contributions.
There’s no major urgency for Miami to complete a deal at this time. Stowers remains under club control for another four seasons and will play the upcoming 2026 campaign at age 28. Any extra seasons tacked on via a contract extension would begin with his age-32 campaign. Miami already controls the slugger for the majority of his remaining prime seasons, so it’s understandable if they’re wary of going particularly long-term on the late-blooming slugger — even on the heels of an All-Star campaign. At the same time, Stowers will be arbitration-eligible for the first time next winter. His gaudy power output should lead to a nice year-one salary in arbitration, which will lessen some of his own urgency to take anything that feels significantly below market value.
Stowers’ path from a well-regarded but somewhat blocked prospect in Baltimore to a starter in Miami is one that fellow outfielder Owen Caissie will hope to follow in 2026. The former Cubs top prospect, acquired as the headliner in this offseason’s Edward Cabrera trade, chatted with SportsGrid’s Craig Mish (video link) about the emotions of being traded and the excitement over what’s clearly a more straightforward path to playing time in South Florida.
“I thought I was pretty blocked,” said Caissie in reply to Mish asking him about the opportunity (or lack thereof) with his former team. “…Chicago is pretty stacked. It’s pretty tough for a guy to break through. There’s a big payroll and everything like that. … The Cubs have had a great squad the last couple years.”
Opportunities have indeed been limited for young outfielders in Chicago. Ian Happ and Seiya Suzuki have been mainstays on the roster for several years. Cody Bellinger was with the Cubs from 2023-24. The acquisition of Kyle Tucker plugged him into an everyday role in 2025 (after Bellinger’s departure), and Pete Crow-Armstrong has emerged as the primary center fielder (and won’t often be subbed out, due to his brilliant defense).
Caissie has far fewer obstacles in front of him with Miami. Stowers will occupy one corner, and Jakob Marsee is penciled into center after an impressive two-month run to close out the 2025 season. Caissie, who slashed .286/.386/.551 with 22 homers in 99 Triple-A games last year, is the on-paper favorite for work in right field but will likely still need a nice performance in camp to earn the spot rather than have it handed to him.
Elsewhere in camp, there’s at least some mild concern regarding right-hander Janson Junk. The 30-year-old righty had his own breakout showing in Miami last season and is vying for a rotation spot this spring, but he rolled his ankle Tuesday during workouts and was in a walking boot yesterday, De Nicola writes. The team was sending Junk for imaging to determine how severe any damage might be.
Junk, who described himself as “day to day” with the ankle issue, is on his sixth team since 2021 but turned in 110 innings of 4.17 ERA ball for Miami last year. Sixteen of his 21 appearances were starts. He fanned 17.9% of opponents against a microscopic 2.9% walk rate. Whether he ends up being named Miami’s fifth starter or heads to the bullpen for a swing role, Junk figures to make the Opening Day roster as long as he’s healthy. He’s out of minor league options and thus can’t be sent to Triple-A without clearing waivers, which wouldn’t happen after last year’s solid performance.
Marlins Select Seth Martinez
The Marlins announced Wednesday that they’ve selected the contract of righty Seth Martinez from Triple-A Jacksonville and placed fellow righty Janson Junk on the 15-day injured list due to ulnar nerve irritation in his right arm. Miami also recalled right-hander Freddy Tarnok from Jacksonville and optioned lefty Josh Simpson to Triple-A in his place. The Fish already had an open spot on the 40-man roster, so a corresponding 40-man move for Martinez wasn’t necessary.
The call back to the big leagues is a nice early birthday present for Martinez, who’ll turn 31 on Friday. The Arizona State product has pitched in parts of four major league seasons, all with the Astros, for whom he suited up in 2021-24. Martinez has 137 1/3 innings at the big league level in his career, during which he’s produced a 3.93 ERA (4.24 FIP, 4.19 SIERA) with a 20.7% strikeout rate, a 9.2% walk rate and a 39.6% ground-ball rate.
Martinez came to the Marlins via waivers at the end of a tumultuous offseason. Houston placed him on waivers back in November, setting off a string of transactions that sent him from the D-backs, to the Marlins, to the Mariners and back to Miami over a span of four months. The Fish finally succeeded at passing Martinez through waivers at the end of spring training, and he’s spent the entire year with their top affiliate in Jacksonville, where he’s pitched well.
In 43 2/3 innings with the Jumbo Shrimp, Martinez has a 3.71 earned run average. He’s fanned a strong 28.9% of his opponents against a 9.6% walk rate that’s just barely north of the 9.3% MLB average for relievers. He’s sitting 89-90 mph with both his four-seamer and sinker, but Martinez is using his slider more than at any point in his career; his 46.7% usage rate actually makes the slider his primary offering. It’s worked well thus far, evidenced not only by the previously mentioned rate stats but also a sharp 13.1% swinging-strike rate and poor batted-ball metrics from his opponents (87.5 mph average exit velocity, 33.9% hard-hit rate).
This could prove to be little more than a cup of coffee for Martinez, but he’s pitched well enough in Triple-A and has enough track record that it wouldn’t be too surprising if he pitched his way into some staying power. Martinez is out of minor league options, so he can’t simply be sent back to Triple-A. He’d need to pass through waivers, and his prior outright assignment means he’d have the right to elect free agency even in that scenario. If he does stick around on Miami’s roster, he can be controlled for four additional seasons.
As for Junk, it’s an ill-timed injury for a journeyman righty who’d created some staying power of his own. Miami is Junk’s sixth organization since 2021, and he came to the Fish with a 6.75 ERA in 40 career big league innings. He’s unlocked something in South Florida, however, tossing 88 innings with a 4.09 ERA. Janson’s 17.2% strikeout rate could charitably be described as pedestrian, but he’s shown some of the best command in the majors this year, issuing a walk to only 2.8% of his opponents. The 29-year-old had solidified himself in the Marlins’ rotation with that performance.
Time will tell whether Junk makes it back to the mound this year, but with only a month left on the regular season calendar, even minor injuries can prove to be season enders. If his season is finished, it’ll easily be the most successful of his career. Miami can control Junk for another five seasons if they choose, and he won’t be eligible for arbitration until the 2027-28 offseason.
Marlins Select Janson Junk
The Marlins are selecting the contract of right-hander Janson Junk, according to a team announcement. Right-hander Lake Bachar was optioned to Triple-A to make room for Junk on the active roster, while a 40-man roster spot was opened up by transferring catcher Rob Brantly to the 60-day injured list.
Junk, 29, was a 22nd-round pick by the Yankees back in 2019 who made his big league debut with the Angels back in 2021. Once a fairly well-regarded pitching prospect, Junk pitched to a 4.74 ERA and a 5.22 FIP in 24 2/3 innings spread across seven appearances (six starts) in the majors during the 2021 and ’22 seasons. Following the 2022 campaign, the Angels traded Junk to Milwaukee as part of the package for outfielder Hunter Renfroe. Junk didn’t get much of an opportunity in the majors with the Brewers either, however, pitching just 15 1/3 innings for the club with a 5.87 ERA and 5.22 FIP between the 2023 and ’24 seasons.
Those struggles in Milwaukee culminated in Junk eventually being bounced around the majors in the second half of last year. Junk was designated for assignment by the Brewers in late July and was claimed briefly by the Astros before being DFA’d once again and finding himself in Oakland. Junk appeared in just one game for the club but surrendered seven runs without recording an out and was eventually outrighted off the club’s 40-man roster in September of last year. He then reached minor league free agency during the offseason and signed a minors pact with the Marlins back in February.
Junk’s time with the Marlins organization has seen him pitch extremely well at Triple-A Jacksonville. In nine appearances (eight starts) for Miami’s affiliate, he’s pitched to a 2.48 ERA with a 22.5% strikeout rate in 45 1/3 innings of work. For a pitcher with a 4.03 career ERA across five seasons at the Triple-A level, it’s a noticeable step forward, and those impressive minor league numbers were clearly enough to get the attention of a Marlins club that’s always looking for extra arms who can pitch in flexible roles. He’ll join the Miami bullpen for the time being, where there should be opportunities for advancement into a late-inning role if he performs well given the club’s lackluster 5.09 bullpen ERA.
As for Bachar, the soon-to-be 30-year-old hurler is in his second season with the big league Marlins. He’s posted a 4.50 ERA in 36 innings of work as an up-and-down reliever for the club to this point, and while that league average (101 ERA+) production is hardly exciting, it’s the sort of effectiveness that should keep him in the conversation for appearances with the rebuilding Marlins going forward. Brantly, meanwhile, heads to the 60-day IL after sustaining a lat strain in April. That’ll keep him out of commission for at least another month, though a trio of Liam Hicks, Agustin Ramirez, and Nick Fortes seem perfectly capable of holding down the fort while Brantly is on the shelf.
Marlins Sign Janson Junk To Minor League Deal
The Marlins announced that right-hander Janson Junk has been signed to a minor league deal. The Beverly Hills Sports Council client will be in major league spring training as a non-roster invitee.
Junk, 29, spent 2024 bouncing around the league. He started the year with the Brewers as a depth arm, getting frequently recalled and optioned back down to the minors. The club designated him for assignment in late July when Devin Williams came off the 60-day injured list. Junk was put on waivers and claimed by the Astros, then went to the Athletics via another waiver claim about a month later. The A’s outrighted him off their roster shortly thereafter and he was able to elect free agency at season’s end.
Around those transactions, he was only able to toss eight innings in the majors. He also got limited big league work in the previous three campaigns, so he now has a 6.75 earned run average in 40 innings in his career overall. His 18% strikeout rate in that time is subpar but his 5.8% walk rate has been good and his 44.3% ground ball rate around average.
His minor league track record has naturally been larger and more impressive. Over the past four years, he has tossed 367 innings on the farm with a 3.83 ERA, 20.5% strikeout rate and 7.2% walk rate. That includes 60 1/3 Triple-A innings in 2024, working both out of the rotation and bullpen, with a 3.58 ERA, 21.3% strikeout rate, 8.3% walk rate and 46.3% ground ball rate.
The Marlins have a fair amount of uncertainty on their pitching staff. In the rotation, they recently traded Jesús Luzardo and lost Braxton Garrett to season-ending surgery. Eury Pérez will return from his surgery this year, but probably not until the All-Star break. As of now, Sandy Alcántara, Ryan Weathers, Edward Cabrera and Max Meyer project as the front four, with guys like Valente Bellozo, Adam Mazur and others in the mix for back-end jobs.
In the bullpen, the Marlins traded away Tanner Scott, A.J. Puk, Bryan Hoeing, Huascar Brazobán and JT Chargois at the deadline. They current have no relievers with more than four years of service time, with Anthony Bender the only one over the three-year mark and Andrew Nardi the only other one beyond the two-year line. In short, it’s wide open.
Since Junk has pitched both as a starter and reliever, he’ll give the Fish a bit of extra depth in both departments. If he makes it to the majors, he is out of options, which will limit his roster flexibility. If he does get a roster spot, he has less than a year of service time, so he can be cheaply retained for the foreseeable future.
A’s Designate Janson Junk For Assignment
The A’s have designated right-hander Janson Junk for assignment and recalled left-hander Brady Basso from Triple-A Las Vegas, the team announced Thursday.
Junk was claimed off waivers just six days ago. He made his first and only appearance for Oakland last night in a nightmare outing wherein he faced eight batters and allowed them all to reach base (six hits, two walks). Junk was charged with seven earned runs and did not record an out.
Disastrous as that outing was, Junk has been quite effective in Triple-A this season and had a nice year at that level with the Brewers in 2023. He’s pitched 50 innings with a 3.60 earned run average for the Triple-A affiliates of the Brewers and Astros this season, and last year the now-28-year-old righty logged 140 innings with a 4.18 ERA, 15.8% strikeout rate and 7.4% walk rate for Milwaukee’s top affiliate in Nashville. Junk’s calamitous outing with the A’s sent his career ERA in 40 major league innings careening from 5.18 to 6.75. He’s been far better in Triple-A, with 266 innings of 4.26 ERA ball and consistently strong walk rates.
Basso, 26, made his big league debut earlier this season and tossed 3 1/3 innings. The former 16th-round pick breezed through six Double-A starts this year (2.84 ERA, 30.5 K%, 2.9 BB%) and has now appeared in 16 Triple-A games (12 starts). In 67 2/3 innings in Vegas, he’s logged a 5.19 ERA while fanning 26.4% of his opponents against a 7.5% walk rate.
Athletics Claim Janson Junk
The Athletics announced that right-hander Janson Junk has been claimed off waivers from the Astros. Outfielder Miguel Andujar was moved to the 60-day injured list to create roster space, as Andujar’s season is already over due to a core surgery.
Junk’s August has been bookended by a pair of waiver claims, as the Astros initially plucked him off the Brewers’ wire at the start of the month. He didn’t receive any playing time in the majors during his limited time with Houston, and he struggled to a 6.14 ERA in 14 2/3 innings with Triple-A Round Rock. Junk was used exclusively as a starter with Round Rock, as opposed to his usage as both a starter and reliever with Triple-A Nashville earlier this season, when he had a 2.55 ERA over 35 1/3 frames.
Junk has generally decent numbers across parts of four seasons at the Triple-A level, but that hasn’t translated into much success (or even regular playing time) during his brief stints in the big leagues. Over 40 career MLB innings with Los Angeles and Milwaukee since he debuted with the Angels in 2021, Junk has a 5.18 ERA, 20% strikeout rate, and five percent walk rate.
Since the rebuilding A’s are looking to evaluate talent and fill innings over the remainder of the season, Junk might well get another opportunity to show that he can do against big league hitters. Junk will be out of minor league options next year, so Oakland or any other team will need to designate the righty for assignment before trying to send him back to Triple-A.
Astros Designate Janson Junk For Assignment
The Astros announced that they have signed outfielder Jason Heyward and optioned outfielder Chas McCormick, two moves that were previously reported. To open a 40-man spot for Heyward, right-hander Janson Junk has been designated for assignment. The club also reinstated right-hander Ryan Pressly from the injured list and optioned left-hander Bryan King.
Junk, 28, was just claimed off waivers from the Brewers at the start of this month and has been kept on optional assignment since then. He made four starts for Triple-A Sugar Land, allowing 10 earned runs in 14 2/3 innings.
Since the trade deadline has passed, the Astros will have to put him back on waivers in the coming days. He could perhaps garner interest from clubs in need of innings. He only has four major league frames on his track record so far, with an unimpressive 5.18 ERA. But from 2021 to the present, he has tossed 356 2/3 minor league innings with a 3.84 ERA. His 20.4% strikeout rate in that time is a bit below average but his 7.4% walk rate is strong and he’s also had solid ground ball rates.
He will be out of options next year but can still be optioned for the rest of the 2024 season. He has less than a year of service time and can therefore be controlled well into the future, but he will have less roster flexibility by the next campaign.
Astros Claim Janson Junk
The Astros claimed right-hander Janson Junk off waivers from the Brewers, tweets Todd Rosiak of the Milwaukee Journal-Sentinel. Junk was designated for assignment when Milwaukee reinstated Devin Williams from the 60-day injured list. Houston already had an open spot on the 40-man roster, so no additional moves were necessary. Junk has been optioned to Triple-A Sugar Land and will give the ‘Stros some additional depth.
This is the final option year for Junk, 28, who’s pitched in the big leagues in each of the past four seasons. He’s only received scattered looks during his time with the Angels and Brewers, logging a combined 40 innings with a 5.18 ERA, 18.8% strikeout rate, 5% walk rate and 44.8% ground-ball rate. He’s worked both as a starter and reliever in his pro career, and though he’s primarily spent the season in the bullpen with the Brewers’ Triple-A Nashville affiliate, he’s frequently worked in multi-inning stints throughout the summer.
Junk’s big league numbers may not be particularly sharp, but he sports a tidy 2.55 earned run average in 35 1/3 Triple-A frames this season. He’s punched out 23.6% of his opponents there against a 10.1% walk rate. Junk has been outstanding of late, too. He’s rattled off 17 straight scoreless frames in Nashville, logging a 19-to-7 K/BB ratio along the way and only yielding a dozen hits in that time. In parts of four Triple-A seasons, Junk has a 4.15 ERA over the life of 251 1/3 innings.
