MLB Rumors: Red Sox Trading Triston Casas?

March 18, 2026
Boston Red Sox first baseman Triston Casas rounds the bases during 2025 game.

Triston Casas is back in trade rumors, but is it really the right time? 

The Boston Red Sox brought in Willson Contreras to take over at first base, and with Casas also missing Opening Day, his long-term fit with the club looks a lot less certain than it once did. 

But even with his name starting to circulate again, this feels like the wrong moment for Craig Breslow to seriously entertain moving him. 

Casas still has upside, yet his value is nowhere near where Boston would want it to be right now.

Triston Casas still has intrigue for Red Sox trade talks

There’s a reason teams would still ask about Casas. 

He is only 26, he finished third in American League Rookie of the Year voting in 2023, and the offensive ceiling is absolutely still there. 

In that 2023 season, he slashed .263/.367/.490 with 24 home runs in 132 games, and over his big league career he has posted a strong 118 OPS+ with 45 home runs. 

For clubs out there looking for a long-term first baseman, that kind of profile will always get attention, even more so when the player is controllable through 2029.

That said, the stock is just not where it used to be. 

Injuries have derailed much of his momentum, first with rib issues that limited him to 63 games in 2024, then with the left patellar tendon rupture that ended his 2025 season after just 32 games. 

He hit only .182 with a .277 on-base percentage before going down last year, and he still is not cleared for full game action. 

Casas has been taking live at-bats in minor league games and has shown some encouraging signs with the bat, but he is not yet running the bases normally or playing the field. 

That's not exactly the profile of a player you try to cash in on right now.

Red Sox may be smarter to wait on a Casas move

It's a tricky situation for Boston. 

Yes, Contreras gives the Red Sox cover at first base, and yes, the roster crunch could eventually force a bigger decision. 

But trading Casas now would almost certainly mean selling low on a player who still has middle-of-the-order upside. 

Even some mock trade chatter out there involving the Los Angeles Dodgers and Bobby Miller comes with the same holdup. Boston would need to believe the return is strong enough to justify giving up on Casas before he reestablishes his value.

Let Casas keep building back up, let him prove he is healthy, and let him show that the power and plate discipline are still intact. 

If he returns around May and starts looking like the hitter who mashed 15 homers with a .317/.417/.617 line in the second half of 2023, then the conversation changes completely. 

Until then, the Red Sox can listen, but this does not feel like the best time to make a Triston Casas trade.
