Triston

Casas

There’s a shroud of mystery and uncertainty swirling around Casas as he continues to work his way back from last year’s serious knee injury. The Red Sox acquired veteran slugger Willson Contreras to take over at first base, which likely limits the former top prospect to DH until further notice. It’s too early to write Casas off completely since he’ll be just 26 years old on Opening Day but there are more questions than answers at this stage of his career. There should be some clarity regarding his immediate outlook and role based on how he performs in Grapefruit League action. He seems likely to open the year back in Triple-A Worcester but it wouldn’t be shocking to see him make Boston’s season-opening roster, especially if the Red Sox decide to move either Jarren Duran or Masataka Yoshida.

Casas is a bit of a forgotten man in Boston, but the soon-to-be 26-year-old could be the favorite for DH duties as of now. Casas has had some unfortunate injuries in his brief career, including a season-ending knee injury last season, but he has an .800 career OPS in 251 MLB games. He was once one of the top prospects in baseball and still could have a bright MLB future ahead of him.

The Cardinals will get righties Hunter Dobbins, Yhoiker Fajardo and Blake Aita and will send Boston $8 million, according to Passan. Contreras, who is owed $41.5 million for the next two years or, if his option is picked up, $54 million for the next three, will apparently be waiving his no-trade clause to take over as Boston’s first baseman. That means Triston Casas could open up in Triple-A if healthy, though if he impresses in the spring, there’s also the chance the Red Sox could go with him and Contreras splitting time between first and DH. The Cardinals figure to install Alec Burleson at first, which would open an outfield spot back up for Jordan Walker alongside Lars Nootbarr and Victor Scott II. Contreras hit .257/.344/.447 with 20 homers in 135 games last season in his first year since giving up catching.

While the Red Sox are hopeful that Triston Casas will be able to return early during the 2026 season, it sounds like they’re trying to secure a backup plan just to be on the safe side. The Red Sox already completed one trade with the Cardinals — acquiring right-hander Sonny Gray — and it’s unclear if the discussions around Contreras were a part of those talks or a separate discussion. Even if a deal were to be consummated, the 33-year-old slugger holds a full no-trade clause and would need to approve the swap.

The Mets missed the playoffs despite Alonso’s huge year on offense, and the team is now “preaching defense or in the words of Stearns, ‘run prevention,’” which means that Alonso may not be the best fit. However, the Red Sox have an opening at first base and need the power that Alonso could provide them. Even if Triston Casas (knee) were to begin the year healthy, he and Alonso could split the first base and designated hitter roles.

Casas is three months removed from major knee surgery after suffering a patellar tendon rupture in the first week of May. The 25-year-old is not yet close to baseball activity, but the team is excited by the progress he is making in the training room. “He’s in a really, really good place physically and mentally,” said team president Craig Breslow. Casas had previously claimed he would be ready by Opening Day, and while there’s a long way to go before we can feel as confident as he is, he’s certainly off to a good start in his recovery.

It was previously reported that the Rays would not be interested in trading Díaz, but they have since struggled to the point where the playoffs are looking less likely, and they are entertaining the possibility. Cotillo suggests that “Red Sox decision-makers were privately wondering if the Rays could make Díaz available” and that the first baseman “fits the roster perfectly as a clear upgrade over the Abraham Toro/Romy Gonzalez platoon at first base.” Díaz is also under control beyond 2025, which the Red Sox like because “privately, the club is not guaranteeing that Triston Casas, who is rehabbing from a season-ending knee injury, will be the starter in 2026.”

Casas underwent season-ending left knee surgery last month after suffering a patellar tendon rupture. The 25-year-old first baseman is expected to be off crutches in the next few weeks and will spend the next few months rehabbing down in Fort Myers. It sounds like there’s a chance he’s ready for spring training and could be in next year’s season-opening lineup.

The move opens up a spot on the 40-man roster for Alex Bregman. Casas will miss all of 2025 after undergoing season-ending surgery on his left patellar tendon, and there’s no guarantee he’ll be ready for the start of 2026, either.

Casas suffered a left patellar tendon rupture on Friday night and is facing a lengthy absence. Historically speaking, it’s one of the more challenging injuries to make it back from, with recovery times typically in the six-month range. There should be an update on his long-term prognosis at some point in the coming days. Fantasy managers shouldn’t expect him back until the outset of the 2026 campaign.
