Twins Claim Connor Gillispie

By | at

The Twins have claimed right-hander Connor Gillispie off waivers from the Marlins, reports Bobby Nightengale of the Minneapolis Star Tribune. He’s been optioned to Triple-A St. Paul. Miami had designated Gillispie for assignment last week.

Gillispie, 27, was an offseason waiver claim by the Marlins (from the Braves, who’d signed him to a big league deal) back in January. He parlayed a strong spring showing into a spot in Miami’s rotation to open the season. He made six starts, the first three of which went fairly well (3.86 ERA in 14 innings), before being pummeled for 19 runs over his next dozen innings. The Marlins optioned him to Triple-A Jacksonville at that point, and he hasn’t pitched in the majors since, leaving Gillispie with a bleak 8.65 ERA in 26 MLB frames this season.

Things have gone better in the minors. Gillispie has pitched 33 2/3 innings with a 4.28 ERA. His 15.7% strikeout rate is a well shy of league average average, however, and his 11.4% walk rate is quite high. The right-hander’s average 90.9 mph average fastball this year is down from the 91.5 mph he posted last year with the Guardians’ Triple-A affiliate.

That 2024 season in Cleveland’s system was solid. Gillispie pitched 113 1/3 innings with a 4.05 ERA, a 25% strikeout rate and a 10.1% walk rate. That led to a brief big league debut with the Guardians, wherein Gillispie tossed eight innings of relief and held opponents to two runs with an 8-to-5 K/BB ratio.

Gillispie is in the second of three minor league option years. He’ll give the Twins some depth either at the back end of the rotation or as a long reliever for a reeling pitching staff. The Twins were among the league leaders in most pitching categories for the better part of six weeks before injuries to Pablo Lopez and Zebby Matthews thinned their rotation.

The Twins have since endured a series of short starts, even from some of their more established arms, that has led to a heavily worked bullpen and prompted them to lean heavily on waiver claim Joey Wentz and utilityman Jonah Bride for mop-up work in several blowout games. Minnesota has dropped nine of its past ten games, falling below .500 and sliding considerably down the playoff standings in the American League.

Marlins Select Josh Simpson, DFA Robinson Piña

By | at

The Marlins have selected left-hander Josh Simpson’s contract from Triple-A Jacksonville, as first reported by Isaac Azout of Fish on First and later confirmed by the club. In a corresponding transaction, right-hander Robinson Piña was designated for assignment. Azout notes that Simpson will likely be available to pitch this afternoon in relief of Eury Pérez, who is making his third start of the season and has yet to throw more than four innings in a game.

If Simpson does indeed make it into today’s contest, he will be making his MLB debut. The 27-year-old did briefly get called up to the majors by the Marlins in 2023 but was DFA’d before he had the chance to get into a game. A 32nd-round pick by the Marlins all the way back in 2019, Simpson impressed during his pro debut in following the 2019 draft with a 2.25 ERA between rookie ball and the Low-A level that season. Unfortunately, his development was thrown off track by the cancelled minor league season in 2020. By 2021, he was struggling badly with his effectiveness at the High-A level, and while a move to Double-A the following season saw his numbers improve he never really mastered the Triple-A level in parts of three seasons there.

That is, of course, until this year. In 27 appearances (31 2/3 frames) this year for the club’s Jacksonville affiliate, Simpson has pitched to a solid 3.41 ERA. His underlying numbers are less encouraging, as he pairs a 12.7% walk rate with a strikeout rate on the wrong side of 20%. Simpson’s production this year has largely been thanks to keeping the ball in the park extremely effectively, as he’s allowed just one home run so far with a paltry 26.2% Hard-Hit rate. He’ll need to work on his command if he’s going to find success in the majors, but that ability to miss barrels and limit hard contact should help his arsenal play up a bit as he attempts to make a case for himself as a major league arm.

Making room for Simpson on the roster is Piña, who made is big league debut just yesterday. The 26-year-old product of the Dominican Republic allowed a solo home run but no other traffic in his inning of work for the Marlins yesterday. Piña worked mostly as a starter in Triple-A before his move to the major league bullpen, and had a 3.47 ERA across 13 appearances (11 starts) at the level prior to his promotion. The Marlins will have one week to either work out a trade involving Piña or attempt to pass him through waivers. If he clears waivers unclaimed, the Marlins will be able to outright him to the minors as a non-roster depth option moving forward.

Trade Deadline Outlook: Miami Marlins

By | at

MLBTR has kicked off a new series for Front Office subscribers! Over the next few weeks, we’re going team-by-team and examining every club’s deadline outlook as trade season approaches. There are some teams that’ll be easy to categorize as buyers or sellers, but many still find themselves right on the bubble where their play over the next four to six weeks takes on extra importance.

There’s nuance even for teams that are clearly into buy or sell mode. Where are those organizations from a payroll perspective? Are the buyers all-in for 2025 or just opening a long-term competitive window? Are the sellers committed to a multi-year rebuild, or are they likely to focus only on moving rentals while hanging onto players who are controllable beyond this season? Might the baseball operations leader be on the hot seat, and if so, how could that impact their deadline decisions?

We’ll start the series with a focus on teams that have moved to the far ends of the standings, giving a bit more time for the fringe contenders to clarify their plans. This edition focuses on the Marlins, a franchise which has been undergoing a huge pivot, despite making the playoffs two years ago.

Record: 29-44 (0.0% playoff probability)

Sell Mode

Impending Free Agent: Cal Quantrill

The Marlins have already shipped out a lot of their veteran players in recent years and also made little effort to bolster their roster in the offseason. They signed two free agents this past winter. One of them was Eric Wagaman, who came into this year with 18 games of big league experience and who can be controlled until he reaches six years of service time.

The other was Cal Quantrill, who signed a one-year, $3.5MM deal. The Marlins will surely make him available this summer, though the value will surely be modest. He's a back-end guy, at best, and contending clubs won't pay a huge price for that.

A playoff-caliber starter would fetch a much larger return, but Quantrill has a 5.68 earned run average over his 14 starts this year. There's probably a bit of bad luck in there, with his FIP at 4.43 and his SIERA at 4.49, but his strikeout rate has been subpar in every full season of his career. The Pirates got a lottery-ticket prospect for Martín Pérez last summer, and that's probably what the Marlins will be looking at here.

Controllable Trade Candidates: Sandy Alcantara, Jesús Sánchez, Anthony Bender, Edward Cabrera, Ryan Weathers, Max Meyer, Otto López, Kyle Stowers, Janson Junk, Calvin Faucher, Derek Hill, Dane Myers, Xavier Edwards, Andrew Nardi, Jesús Tinoco, Ronny Henriquez, Nick Fortes

Marlins Outright Luarbert Arias

By | at

The Marlins sent right-hander Luarbert Arias outright to Triple-A Jacksonville, according to the MLB.com transaction log. He’d been designated for assignment last weekend when Miami called up Freddy Tarnok.

Miami added Arias to the 40-man roster at the beginning of last offseason. He was coming off a 3.04 ERA over 68 Triple-A innings and would have qualified for minor league free agency if the Fish didn’t select his contract. That put him on the doorstep of the majors, and he received his first MLB call within the season’s first week. Arias began his career with a three-inning scoreless appearance against the Mets on March 31. He gave up runs in each of his next three outings and was optioned back to Triple-A by the middle of April.

The 24-year-old had another brief MLB stint at the end of April. He’d been on optional assignment in Jacksonville since the start of May. Arias hasn’t had the same success he had there a year ago. His 3.93 ERA over 18 1/3 innings isn’t terrible, but he has recorded only seven strikeouts while issuing 13 walks. MLB opponents tagged him for 11 runs through 9 1/3 frames.

Arias has never been outrighted and has almost no MLB service time. He therefore doesn’t have the right to elect free agency. He’ll remain in Jacksonville without occupying a 40-man roster spot and try to recapture last year’s form. He would qualify for minor league free agency at the beginning of the offseason if he doesn’t get back onto the roster before then.

Marlins Designate Connor Gillispie For Assignment

By | at

The Marlins announced that they have selected right-hander Robinson Piña, a move that was reported earlier. In corresponding moves, righty Adam Mazur has been optioned to Triple-A Jacksonville and righty Connor Gillispie has been designated for assignment.

Gillispie, 27, was claimed off waivers from Atlanta in January. He earned a rotation job to start the season but couldn’t hold it. In six starts, he allowed 25 earned runs in 26 innings, leading to an unsightly 8.65 ERA.

That got him optioned down to Triple-A, where he has since logged 33 2/3 innings with a 4.28 ERA. While that was obviously a big improvement, luck was a big factor. He struck out just 15.7% of batters faced in the minors while giving out walks at an 11.4% clip. If it weren’t for a tiny .161 batting average on balls in play, he would have fared far worse, hence his 6.55 FIP.

He’s now been nudged off the 40-man roster and will likely end up on waivers in the coming days. His minor league work prior to this year was better. From 2021 to 2024, he logged 406 innings on the farm with a 4.12 ERA. His 9.6% walk rate was a tad high but he also punched out 24.1% of opponents. He is still optionable for the rest of this year and one further season, so perhaps a club with a need for depth and a plan to get Gillispie on track could have interest. If he clears outright waivers, he would stick with the Marlins as non-roster depth.

Marlins To Select Robinson Piña

By | at

The Marlins are calling up right-hander Robinson Piña for his major league debut, reports Kevin Barral of Fish On First. The team has not announced the move yet. Piña’s contract will need to be selected to what is currently a full 40-man roster in Miami, so the Fish will need to make a corresponding move in that regard.

Piña, 26, will make his big league debut the first time he takes the mound. He spent the 2017-23 seasons in the Angels system before becoming a minor league free agent and signing with the Phillies ahead of the 2024 campaign. The Phils never added him to the 40-man roster, and Piña again became a minor league free agent this past offseason, signing with Miami in his second run through the open market. This time around, he’ll get that coveted first MLB opportunity.

Piña has certainly earned his call to the majors. He’s appeared in 13 games, 11 of them starts, and tallied 57 innings with a 3.47 ERA, a 22.2% strikeout rate, a 6.2% walk rate and a 46.9% ground-ball rate. Command was an issue for him early in his minor league career, but he’s now turned in consecutive minor league seasons with walk rates that clock in considerably south of average. This year’s 92.8 mph average sinker is up a mile per hour over last year’s levels, and Piña has been consistent all season; he hasn’t yielded more than three earned runs in any appearance and has held opponents to two or fewer runs in 10 of 13 outings overall.

Miami has Edward Cabrera lined up to start today, with Janson Junk, Eury Pérez and Sandy Alcantara listed as probables in their next three games thereafter. There’s no need for an immediate spot starter — barring an injury the team has not yet made public — but they could be looking to add some length with Junk having spent the season in a long relief role. The Marlins also have an off-day coming on Monday, so they could option Adam Mazur and skip the fifth starter’s spot next time through the rotation. Doing so would give them options for how best to use Piña, who’s fully stretched out and has topped 80 pitches in five of his past six appearances.

Marlins To Recall Adam Mazur

By | at

The Marlins will recall righty Adam Mazur to start tomorrow evening’s game against Philadelphia, manager Clayton McCullough told reporters (including Daniel Álvarez-Montes of El Extrabase). He’ll go against Ranger Suárez in his team debut. SportsGrid’s Craig Mish first reported that Mazur was likely to get the call. He’s already on the 40-man roster, so the Fish only need to make an active roster move involving a pitcher.

It’s not a big league debut for the 24-year-old Mazur. He took the ball eight times for the Padres last summer. The former second-round pick struggled in his first look at MLB hitters, giving up a 7.49 ERA through 33 2/3 innings. He’d only had five Triple-A starts at the time, as San Diego was pressed into calling him up by injuries to their more established starters. The Padres optioned him back to Triple-A just before the trade deadline.

Three days later, Mazur was on the move. The Marlins acquired him as part of the return for Tanner Scott and Bryan Hoeing last July. Mazur has been on optional assignment to Triple-A Jacksonville for the better part of a calendar year. He struggled over eight starts there last year but has posted better numbers this season. Mazur owns a 3.62 ERA with a 22.2% strikeout percentage and tidy 6.5% walk rate. He has allowed home runs at an elevated rate, but it’s a generally solid performance to earn him his first call to loanDepot Park.

Miami has been operating with a four-man rotation of Sandy Alcantara, Eury Pérez, Cal Quantrill and Edward Cabrera. They lost Max Meyer and Ryan Weathers to injury and have been utilizing bullpen games to handle the fifth starter role. McCullough didn’t specify whether Mazur will get more than one start for this recall, but it stands to reason that he’ll get a real rotation opportunity at some point this year. Alcantara, Quantrill and potentially Cabrera could all be in trade discussions this summer. Quantrill also left tonight’s start early with a leg issue, though McCullough said postgame that it was just a cramp (via Isaac Azout of Fish on First).

Marlins Select Freddy Tarnok

By | at

June 15: The Marlins made it official today, with left-hander Anthony Veneziano optioned to Jacksonville and right-hander Luarbert Árias designated for assignment as the corresponding moves. Árias was added to the club’s 40-man roster in November. He has a 10.61 ERA in 9 1/3 big league innings so far in his career. He has a 3.93 ERA at the Triple-A level this year but with an 8.5% strikeout rate and 15.9% walk rate.

June 14: The Marlins are selecting righty Freddy Tarnok onto the big league roster, reports MLBTR’s Steve Adams. Miami will need to make corresponding active and 40-man roster moves.

Tarnok joined the organization on an offseason minor league deal. He has been working from the rotation at Triple-A Jacksonville. He’s not going very deep into games — he has yet to work more than five innings — but he has managed alright rate production. Tarnok carries a 4.79 earned run average while striking out more than a quarter of opponents. He’s averaging north of 95 MPH on his fastball while mixing in a slider, curveball and changeup. Tarnok is coming off his best start of the season, striking out six across five scoreless innings against Tampa Bay’s affiliate last weekend.

That earns the 26-year-old his first MLB action in two years. Tarnok is a former third-round pick of the Braves who was a solid prospect. Atlanta dealt him to the A’s in the three-team Sean Murphy trade over the 2022-23 offseason. Tarnok had made one relief appearance as a Brave and pitched five times for the A’s. He allowed eight runs in 15 1/3 career innings. His ’23 season ended when he underwent right hip surgery. That lingered into last year and ultimately ended his tenure in green and gold. Tarnok was claimed off waivers by Philadelphia but didn’t make an MLB appearance for the Phils and was outrighted off the 40-man roster at the beginning of the winter.

Miami needs a fifth starter after losing Max Meyer and Ryan Weathers to the injured list. They welcomed Eury Pérez back from his Tommy John rehab on Monday to fill one spot. They haven’t settled on the final spot, though Janson Junk worked nearly six innings of relief during a bullpen game today against Washington. Junk could assume a more traditional rotation role moving forward, but they used another five relievers this afternoon. Tarnok gives them a fresh arm capable of working multiple innings with Pérez slated to start tomorrow.

Marlins Place Ryan Weathers On 60-Day IL With Lat Strain

By | at

The Marlins announced that left-hander Ryan Weathers has been placed on the 60-day injured list due to a lat strain. Righty Eury Pérez has been reinstated from the 60-day IL, as was reported last week. Isaac Azout of Fish on First reported on Weathers prior to the official announcement.

It’s an unfortunate development for Weathers, who has had a stop-and-start career with his flashes of promise usually proving to be brief. A seventh overall pick of the Padres, he was once a top 100 prospect but struggled in his first tastes of the majors. He had a 5.73 earned run average through his first 143 big league innings when the Marlins traded for him in 2023.

In Miami, he showed some hints of a breakthrough last year. He logged 86 2/3 innings over 16 starts with a 3.63 ERA. His 21.8% strikeout rate was around average, while his 6.5% walk rate and 46.6% ground ball rate were both strong marks. Unfortunately, injuries capped the overall workload. A strain in his left index finger sent him to the IL in June and it took him over three months to return, with his final three starts occurring in September.

This year, injuries have interfered again. In mid-March, he suffered a forearm strain that sent him to the IL to start the year. He was reinstated from the IL and put up some decent numbers, with a 3.28 ERA, 22.5% strikeout rate, 7.8% walk rate and 40.6% ground ball rate in five starts this year. Unfortunately, he’s now on the shelf again. The specifics of the injury are still lacking but the fact that he’s been quickly placed on the 60-day IL after just starting on Saturday doesn’t bode well.

The move will seemingly remove any chance of Weathers being a summer trade candidate, as he will be on the shelf past the deadline. Players on the IL can be traded but it wouldn’t make much sense for the Marlins to flip him when his value is low. He can be retained via arbitration for three seasons after this one. The silver lining of the injury absences, for the Marlins, is that he won’t be able to increase his salary very much.

The Fish will have other opportunities to trade him in the future, ideally after he has shown a strong run of health to build value. Or perhaps Weathers can be a part of a competitive club in Miami, depending on how long this ongoing rebuild takes to bear fruit.

For now, the Marlins will proceed without Weathers in the rotation. Pérez jumps into a group that includes Sandy Alcantara, Cal Quantrill and Edward Cabrera, with guys like Valente Bellozo also in the mix. Max Meyer is on the IL himself but his hip impingement seems minor and he could be back shortly.

With the club sporting a 24-39 record that has them ahead of only the Rockies in the National League, it’s expected that they will be broadly open to trades. In recent years, players like Luis Arráez, Jazz Chisholm Jr. and Jesús Luzardo have been sent out of town even with years of club control remaining. As mentioned, Weathers is far less likely to be moved now, though he will ideally be able to jump back into the rotation late in the year and build some more innings going into 2026.

Poll: Should The Marlins Trade Ryan Weathers?

By | at

When it comes to trade candidates on the Marlins, the majority of the focus has been squarely on right-hander Sandy Alcantara. A recent Cy Young award winner who missed last season while rehabbing Tommy John surgery, Alcantara is earning a healthy salary on a team that is seemingly always looking for opportunities to lower its already-meager payroll and has enough team control remaining for rival clubs to convince themselves to part ways with prospects they’d never consider dealing for a rental arm.

That all makes Alcantara a sensible and attractive trade candidate on paper, but a major issue with those plans has emerged this year: he simply isn’t pitching very well. The righty’s 7.89 ERA through 12 starts is the worst mark among starters with at least 50 innings this year, and even more advanced metrics like his 5.04 FIP and 4.85 SIERA are the 11th- and tenth-worst figures in the sport respectively. It’s going to be hard to convince opposing teams to pay a premium for Alcantara as he’s currently pitching, and that’s a problem for a Miami club that’s in the midst of a deep rebuild.

While Alcantara might not be pitching like the front-line starter the team was hoping to be able to market to needy clubs this summer, another intriguing arm has inserted himself into the discussion with a strong start to the season: left-hander Ryan Weathers. The 25-year-old started the 2025 campaign on the injured list due to a forearm strain he suffered during Spring Training, but in four starts since returning he’s looked nothing short of excellent with a 2.49 ERA, 25.3% strikeout rate, and a 43.1% ground ball rate. Those peripherals don’t quite live up to that ERA, but even his 3.60 SIERA to this point in the year puts him on par with arms like Merrill Kelly and David Peterson who have established themselves as solid mid-rotation, playoff-caliber starters.

On top of his solid performance, Weathers would also be extremely attractive as a trade candidate because he’s making less than $780K this season and comes with plenty of team control. The southpaw won’t be a free agent until the end of the 2028 season, so even clubs facing tight budget restrictions in the short term or who aren’t interested in adding long-term salary commitments could have interest in his services if he’s made available. Weathers’ combination of strong results and a team-friendly contract situation could make him an extremely valuable trade asset for the Fish this summer.

With that being said, there are certainly strong reasons to think the Marlins may not want to part ways with the southpaw. Weathers is still just 25 years old and has yet to complete a full, healthy big league campaign with the club. Four starts is a small sample size that could make him difficult to market, and while good health should allow him to get more like ten to twelve starts under his belt before trade season kicks into high gear, it’s possible he’ll take a step back and wind up pitching closer to the 3.63 ERA and 4.11 FIP he posted in 16 starts last season going forward. Even if he does keep this level of success up, there’s certainly an argument to be made that Weathers could be dealt at a later date when he’s more established and teams might feel more comfortable surrendering a large trade package for him.

What’s more, Weathers’ three seasons of team control after this one could make the Marlins a bit more reluctant to trade the lefty. Miami surely hopes to be competing for the postseason again before 2029, especially with players like Kyle Stowers, Connor Norby, Agustin Ramirez, and Xavier Edwards showing themselves to be solid pieces this year. A potential front three of Eury Perez, Max Meyer, and Weathers under long-term team control would go a long way to making the Marlins legitimate contenders sooner rather than later, and many of those aforementioned pieces only have one more year of team control than Weathers does. Moving someone like Edward Cabrera, who has the same amount of team control remaining as Weathers but is two years older, could also be a preferable option given that Weathers is set to hit free agency ahead of his age-29 season.

Of course, many of the reasons that Weathers would be difficult to part ways with now could be argued as reasons he should be traded at some point. His injury history may make him less valuable in trade, but the Marlins are seeing right now with Alcantara what struggling after a major arm injury can do to a player’s value. The lefty’s youth would mean he’s in the prime of his career when the Marlins will hopefully be trying to contend again, but it also would make him a prime extension candidate for a club with deeper pockets than Miami. The collection of talent the club has at its disposal is impressive, but it still leans much more towards pitching than offense, so swapping a player like Weathers for a bat with similar control could go a long way to improving the team.

How do MLBTR readers think the Marlins should handle Weathers this summer? Should he be kept off the market entirely, shopped aggressively, or moved only if a team makes an overwhelming offer? Have your say in the poll below:
