Luarbert Arias

Marlins Outright Luarbert Arias

By Anthony Franco | June 19, 2025 at 9:07pm CDT

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 Select Freddy Tarnok

By Anthony Franco | June 15, 2025 at 10:45am CDT

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.

Sixto Sanchez Elects Free Agency

By Anthony Franco | November 4, 2024 at 9:21pm CDT

9:21PM: Sanchez has chosen to become a free agent, Azout reports (X link).

5:26PM: The Marlins have taken Sixto Sánchez off the roster. Miami announced that the former top pitching prospect went unclaimed on waivers and was sent outright to Triple-A Jacksonville. Sánchez has the requisite service time to become a minor league free agent, though the Fish didn’t announce that he has already done so. Miami also outrighted left-hander Josh Simpson and selected the contract of righty Luarbert Arias.

Sánchez was the centerpiece of the J.T. Realmuto trade return. The 6’0″ righty was regarded as perhaps the best pitching prospect in MLB at the time. Sánchez never came close to meeting those lofty expectations. Shoulder injuries have largely derailed his career, as Sánchez has lost huge chunks of time to the IL over the past half-decade. He didn’t throw a single MLB pitch between 2021-23. Sánchez returned to log 35 2/3 innings in a swing role this season, but he surrendered more than six earned runs per nine. Shoulder inflammation ended his season in early June.

Simpson, 27, has yet to make his MLB debut. He had been on the 40-man roster since the end of the 2022 season. Simpson lost most of this season to an ulnar nerve injury that required surgery. He allowed 14 runs (11 earned) across 16 innings between three minor league levels. He’s also likely headed to minor league free agency.

Arias, 23, would have joined them on the open market if the Fish didn’t put him on the 40-man roster. The Venezuelan-born righty had a nice year in a late-inning role for Jacksonville. Arias posted a 3.04 earned run average through 68 innings. He fanned upwards of a quarter of opponents against a 9.3% walk rate. He’s a pure reliever who can compete for a spot in a wide open bullpen as he tries to earn his first big league call.

Isaac Azout of Fish on First first reported that Miami outrighted Sánchez off the roster.
