Marlins Announce Several Roster Moves
The Marlins announced a quartet of roster moves this morning. Infielder Graham Pauley and lefty Dax Fulton were optioned to Triple-A Jacksonville. Right-hander Stephen Jones‘ contract was selected from Double-A, and outfielder Heriberto Hernandez has been recalled as well. Miami had an opening for Jones on the 40-man roster after this week’s DFA of veteran righty Chris Paddack. However, with top prospect Robby Snelling confirmed to be Friday’s starter and needing a 40-man spot, the Fish will now need to make a 40-man roster move between today’s game and tomorrow’s game in order to get Snelling onto the roster.
It’s the first time in nearly a year that Pauley has been sent to the minors. He’s taken the majority of Miami’s reps at third base this season but has struggled immensely, batting just .173/.225/.293 in 81 turns at the plate. Pauley didn’t offer much with the bat last year, either, but his .224/.311/.366 slash (184 plate appearances) was miles better than what he’s posted so far in 2026. Pauley is actually chasing fewer pitches off the plate and making contact on a higher percentage of his swings, but because he’s swinging less often in general and thus taking more called strikes, his walk and strikeout rate have both trended in the wrong direction.
A brief reset for the 25-year-old Pauley could do him some good. He turned in a strong .263/.342/.511 batting line (127 wRC+) in 37 games with the Marlins’ Jacksonville affiliate in 2025, walking at a quality 9% clip against a tiny 11.6% strikeout rate. Given that Pauley plays an above-average third base, Miami would surely take even average offense out of his bat.
With Pauley looking to get back on track in Jacksonville, the Fish will likely turn third base over to utilityman Javier Sanoja, although fellow infielders Leo Jimenez and Christopher Morel could potentially mix in as well. Morel was signed to be the primary first baseman and is a poor defender at third base, but he does have experience there. Connor Norby — who also has experience at third base — has been the primary option at first base, but the Marlins could at least consider sliding him back across the diamond on occasion. Broadly speaking, manager Clayton McCullough will have plenty of scenarios to consider, though none of them stands out as ideal.
Jones, 28, will make his big league debut the first time he gets into a game. He’s a former Rockies draftee who spent the 2025 season in the Padres system and signed a minor league deal with the Marlins over the winter. Jones has opened the 2026 season with 16 2/3 innings and a 3.24 ERA. He’s surrendered six earned runs on 10 hits and a problematic 13 walks, tacking on 19 punchouts in the process. Jones’ 25.7% strikeout rate isn’t supported by his well below-average 8.5% swinging-strike rate, however, and his colossal 17.6% walk rate presents an obvious red flag. He’ll get an opportunity to show he can hack it in the majors, but he’ll need to both improve his ability to miss bats and, more importantly, scale back on those walks if he’s to have any staying power.
Marlins Recall Dax Fulton For MLB Debut
1:45pm: The Marlins have now officially announced that they have recalled Fulton and optioned Kempner.
11:32am: The Marlins are set to recall left-hander Dax Fulton from Triple-A Jacksonville, Isaac Azout of Fish on First reports. Righty William Kempner, who made his own big league debut last night, will be optioned to Jacksonville in his place. Fulton has been a starter for the vast majority of his professional career but will make his debut in the Miami bullpen, Azout adds. Barry Jackson of the Miami Herald reports that left-hander Robby Snelling is still on track to make his big league debut Friday in place of recently DFA’ed veteran Chris Paddack.
Kempner tossed only eight pitches in last night’s debut, so it’s not a matter of him being unavailable. Perhaps the Marlins simply wanted another lefty in the ‘pen after Andrew Nardi tossed 22 pitches yesterday, or perhaps they preferred to add some more length after using five relievers Tuesday. Whatever the rationale, Fulton will head to Miami for his first call to the majors. He’s made five starts and two relief appearances this season in Jacksonville but been hit hard: 20 innings, 17 earned runs, 23 hits, 11 walks, three hit batters and 24 strikeouts.
It’s been a shaky start to his year, clearly, but Fulton is a former second-round pick and well-regarded prospect whose path to the majors has been set back by injuries. Most notably, he underwent an internal brace procedure on his left UCL in June 2023. (Fulton also had Tommy John surgery as an amateur.) That 2023 surgery wiped out his entire ’24 campaign. Fulton returned in 2025 with 103 2/3 innings, posting an unsightly 5.38 ERA with more encouraging underlying marks (3.55 FIP, 23.8% strikeout rate, 47.3% grounder rate).
Fulton is a towering 6’7″ southpaw who’s listed at 245 pounds. He’s sitting 93.6 mph on his heater and can ramp the pitch up to 96-97 at times. The big lefty’s other go-to offerings are a low-80s curveball and an upper-80s changeup, though he’ll occasionally sprinkle in a sinker.
Whether the move to a relief role has any permanence remains to be seen. The Marlins have a good bit of rotation depth even after Paddack’s DFA and offseason trades of Edward Cabrera and Ryan Weathers. The current staff includes Sandy Alcantara, Eury Pérez, Max Meyer and Janson Junk. Snelling, who sits 26th on Baseball America’s just-released update of their top-100 prospects, seems ticketed for a debut Friday.
Fellow lefty Thomas White, ranked even higher at No. 11 overall, will likely debut at some point this season. The Fish also have talented lefty Braxton Garrett in Triple-A — he started last night and is thus not a candidate to return to the big league rotation Friday — alongside swingmen Ryan Gusto and Bradley Blalock. Jacob Miller and Karson Milbrandt, the team’s second- and third-round picks in 2022, are both in their second stints at the Double-A level (with the latter throwing very well at present).
That stock of arms could make the bullpen Fulton’s clearest path to carving out a lasting spot on the big league roster, but he’ll likely need to get back to his pre-surgery form with another stint in Triple-A regardless. If he’s up to provide some length in the bullpen for the next couple days, he’ll be a candidate to be sent back down to Triple-A on Friday — assuming Snelling is indeed promoted for his debut that day.
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.
Marlins To Add Three Players To 40-Man Roster
The Marlins are going to be selecting three players to their 40-man roster ahead of today’s Rule 5 protection deadline, reports Christina De Nicola of MLB.com on X. They are infielders Deyvison De Los Santos and Jared Serna as well as left-hander Dax Fulton. The 40-man roster will be full when the moves are official.
De Los Santos, 22 in June, just arrived with the Marlins at the trade deadline. He was one of two young players that the Fish received when trading lefty A.J. Puk to the Snakes in July. He went on to hit .240/.284/.459 while striking out in 28.4% of his plate appearances after the deal, leading to an 85 wRC+.
The Marlins are undoubtedly hoping that he can get back to the form he showed prior to the trade. In 87 contests this year ahead to the deal, he produced a robust .325/.376/.635 slash line while launching 28 home runs, leading to a 159 wRC+.
De Los Santos is a divisive prospect because the power is exciting but most of his other tools are considered weak. He has played both infield corners but isn’t well regarded for his glovework. He doesn’t take walks or provide much on the basepaths.
Still, a rebuilding club like the Marlins could give him some at-bats and see if the homers make him valuable regardless. The Fish have guys like Jake Burger, Jonah Bride and Connor Norby in their corner infield rotation but De Los Santos will give them some depth there. He already had 99 games of Triple-A experience and could make his major league debut at any time.
Serna, 23 in June, is also a new Marlin. He was one of three players to come from the Yankees as part of the Jazz Chisholm Jr. trade from this summer. He has slashed .265/.358/.435 over his four minor league seasons, walking at a solid 10.8% clip while keeping his strikeouts down to a 16.6% level, production leads to a 123 wRC+.
He may be ticketed for a utility role down the line, as he has played shortstop, second base, third base and a bit of right field as well. His shortstop defense isn’t considered especially strong, so he may end up playing those other positions a bit more. Prior to the trade, he had never played above High-A, so a major league debut might not be imminent. The Marlins did put him into 39 Double-A games and 6 Triple-A games after the swap, but he’s probably ticketed for more time in the upper levels of the minors next year.
Fulton, 23, is unlike the other two in that he was actually drafted and developed by the Marlins. A second-round pick from 2020, he has posted some strong numbers but hasn’t pitched since undergoing surgery on his ulnar collateral ligament in June of 2023. Prior to that surgery, he posted a 4.27 ERA in 229 2/3 innings across multiple levels from 2021 to 2023. His 10% walk rate was a bit high but he punched out 27.6% of batters faced. He will presumably need some time to get back into game shape after missing all of 2024, but he will eventually provide the Marlins with some pitching depth when he is back to full strength.
Marlins’ Dax Fulton To Undergo Elbow Surgery
Marlins pitching prospect Dax Fulton is expected to miss the remainder of the 2023 season due to elbow surgery, Barry Jackson and Craig Mish of the Miami Herald report. The 21-year-old Fulton will undergo a repair but not full reconstruction (i.e. Tommy John surgery) of the ulnar collateral ligament in his pitching elbow. Internal brace and primary repair procedures that are less invasive than a full replacement/reconstruction of the UCL have gained popularity in recent years, though such operations still require lengthy recovery periods.
Fulton becomes the latest in a deep crop of Marlins pitching prospects to incur a major injury setback, although given the sheer volume of quality pitching in Miami’s system and the general attrition rate of pitching prospects, injuries throughout the group were inevitable. Sixto Sanchez has had multiple shoulder surgeries, while Max Meyer and Jake Eder both underwent Tommy John surgery last year.
Fulton isn’t necessarily as touted as that trio, though Keith Law of The Athletic ranked him among the game’s top 100 prospects heading into the season. The former No. 40 overall draft pick pitched to a combined 3.80 ERA in 118 1/3 frames between High-A and Double-A in 2022 and opened the 2023 season back at Double-A. With a strong showing in Pensacola, a promotion to Triple-A was likely — and an eventual 2023 look in the big leagues likely wasn’t entirely off the table.
Fulton already had Tommy John surgery in high school. A second surgery to address the ulnar collateral ligament in his left elbow before he’s even turned 22 years old is an ominous development, but the Marlins are currently hopeful that he’ll be ready for spring training 2024, per the Herald report.
The Marlins placed Fulton on the minor league injured list last month. Prior to landing on the shelf, he’d made six starts and a relief appearance in Double-A Pensacola, pitching to a 5.18 ERA with a 26.4% strikeout rate against a rough 12.8% walk rate. Scouting reports on Fulton tout his plus breaking ball, and Law credits him with a plus changeup as well. Fulton isn’t a flamethrower by today’s standards, topping out at 96-97 mph with his heater and averaging a few ticks shy of that max output.
If Fulton is indeed back to full strength next spring, he could still reach Triple-A next year and be on the doorstep of the big leagues, though with just 33 innings pitched this year, his workload will figure to be monitored. He’s not yet on the 40-man roster and won’t be eligible for selection in the Rule 5 Draft until the 2024-25 offseason, so the Marlins don’t yet need to worry about exhausting his minor league options. The focus for now will be on getting the promising lefty back to full strength and ready for the ’24 campaign.
Marlins Open To Trading From Rotation Surplus Again This Offseason
As last year’s offseason was getting started, reports emerged that the Marlins were considering trading from their stock of young starting pitchers in order to bolster their position player mix. In the end, they did trade Zach Thompson as part of the Jacob Stallings trade, though stopped short of a more headline-grabbing deal.
It seems that strategy is still in play, with Barry Jackson and Craig Mish of the Miami Herald reporting that the club will again look to swap some pitching for some more offense. The report lists ace Sandy Alcantara and the club’s top prospect Eury Perez as the two “untouchable” arms on the team, with the others apparently available for the right price.
In addition to the Thompson trade, there were a few other ways in which the club’s rotation surplus was reduced in the past year. Prospect Max Meyer made two starts before Tommy John surgery put him out of action for the rest of this year and potentially all of next year as well. Sixto Sanchez has continued to deal with shoulder issues, not having thrown in a game since 2020. Elieser Hernandez struggled enough that he got bumped to the bullpen and later optioned to the minors.
Those setbacks aside, the club still has a mix that includes Alcantara, Pablo Lopez, Edward Cabrera, Jesus Luzardo, Trevor Rogers, Braxton Garrett, Daniel Castano, Nick Neidert, with the report listing Lopez, Cabrera and Rogers as logical trade candidates. It also says the club would consider dealing prospects to a rebuilding team in order to get MLB-ready players. Though Perez is apparently not on the table, Jake Eder and Dax Fulton are mentioned as possibilities.
Lopez, 26, is no stranger to trade rumors, having been frequently mentioned both as someone who could be moved and as someone garnering interest around the league. It was reported last week that the Marlins and Yankees had discussed a deal prior to the deadline that would have seen the Fish acquire Gleyber Torres and infield prospect Oswald Peraza, though the Yanks apparently balked at the deal. There’s no real hurry for the Marlins to deal him, as he can be controlled through the 2024 season via arbitration. He’s in his third straight strong season, registering a 3.66 ERA through 25 starts this year. Perhaps most importantly, he has stayed healthy and put aside some concerns after he missed some of last year with shoulder issues. He’s making $2.45MM this year and will get a raise for next season via arbitration, though he will still be plenty affordable and should find lots of interest from other teams.
The 24-year-old Cabrera would make for a very different trade chip, having much more control but less of a proven track record. He just made his MLB debut last year and missed about six weeks this season due to elbow tendinitis. He only has 15 MLB starts on his ledger so far but has shown promise in that time, registering a 3.71 ERA in his young career. He came into this year with just 40 days of MLB service time but was optioned in the spring and didn’t get recalled until June 1, which should lead to him coming just shy of the one-year mark at the end of this season, even if he remains in the big leagues for the rest of the campaign. That means he should still have six years of control beyond this one, though he is in his final option year, which will mean he will need to hold a spot on an MLB roster starting next year or else be designated for assignment.
Rogers, 24, broke out last year with a 2.64 ERA over 25 starts but has regressed here in 2022. He has a 5.85 ERA through 19 starts and has been on the IL for over a month due to back spasms. He should still hold appeal given his previous showing and four remaining years of control, but he’ll certainly have diminished trade value compared to a year ago.
Eder, 23, was a fourth-round draft pick in 2020. The lefty made 15 Double-A starts last year with a 1.77 ERA before undergoing Tommy John surgery in August. He’s out for this year and might be limited in 2023, though the Marlins are hoping to deal him to a rebuilding club, who may not be so concerned about the short-term outlook. Fulton is also a left-hander but much younger, turning 21 in a couple of months. He was a second round pick in 2020, having since climbed up to Double-A. Between High-A and Double-A this year, he has a 4.05 ERA across 102 1/3 innings.
Whether the club can work out a deal with will of course depend upon lining up with another club. A team with designs on immediate contention would likely be more interested in Cabrera, Rogers or Lopez, while a rebuilding club would lean towards Eder and/or Fulton. It will also depend on what that theoretical other club has to offer the Marlins in return. As Jackson and Mish note in their report, the Marlins will be using the final weeks of the season to audition certain position players and evaluate their future roles. JJ Bleday, Lewin Diaz, Jerar Encarnacion and Peyton Burdick are all listed as players trying to secure jobs on the 2023 team. How they fare in those auditions could have an impact on who the Marlins look to target in trades to improve their lineup. The team as a whole has been about 12% below league average at the plate this year, as indicated by their 88 wRC+, a mark that places them 26th in the majors.
