The Red Sox made a significant splash last month by completing their second trade with the Cardinals this offseason, acquiring first baseman Willson Contreras. The move was designed to solidify the position and move away from the platoon approach Boston has relied on in recent seasons.
With Contreras now in the fold, questions naturally arise about how the Red Sox will deploy Triston Casas during the 2026 season. Speaking with reporters at Fenway Fest in Boston on Saturday, Casas said the acquisition did not serve as a wake-up call.
“The first baseman position for this team has lacked, over the last couple of years, the production from that spot,” Casas said. “As of right now, the way that it is, he’s a better player than me and has been for his entire career. To upgrade a position that has been deficient for the last two years is exactly what the team needed. Hopefully, I can come back to the player I was a couple of years ago and know what I can be and contribute to the team in whatever fashion and at whatever position they see fit for me.”
Casas, 25, is currently rehabbing from a ruptured patellar tendon in his right knee, an injury he suffered in a collision while running down the first-base line on May 2. While he’s targeting an Opening Day return, the severity of the injury—combined with his recent injury history—made it impossible for Boston to structure its 2026 plans around the assumption he would be ready at the start of the season.
If healthy, Casas could split time with Contreras at first base and at designated hitter. However, Boston still has Masataka Yoshida on the roster, and he will also need time at DH.

After completing the trade, chief baseball officer Craig Breslow reached out directly to Casas to explain the organization’s thinking.
“It’s no secret that Triston has tremendous potential,” Breslow said before addressing the media about the Contreras acquisition. “But he also hasn’t been able to stay on the field the last couple of years thanks to two really unfortunate—but significant—injuries.”
The Red Sox aren’t questioning Casas’ upside. Instead, they’re acknowledging a pattern that has limited his availability at the major league level—and adjusting accordingly.
“I had a chance to talk to Triston this morning, and what I told him is exactly what I’ll share with all of you,” Breslow said. “We still have a ton of confidence and belief in Triston. What he needs to do is commit to doing everything possible to get back on the field. He’s doing that right now.”
Casas understands why Boston made the move and believes he can still carve out a role on the 26-man roster.
“I don’t have any expectation for that,” Casas said of his role. “I expect (Contreras) is going to get a lot of reps at first base. I don’t think he’s been playing the position for very long, but his defensive numbers have been quite stellar considering the change from catcher to first base. I think everybody’s impressed. I expect him to get that role, at least to start the season, but there’s going to be a lot of turnover on the roster like there is every year. Hopefully, I can find a spot to make my mark.”
Both Breslow and manager Alex Cora have emphasized that getting healthy is Casas’ primary objective early in camp, and it’s likely he’ll be behind other position players when the team reports to Fort Myers next month. Casas hopes to appear in spring training games ahead of his early-season return and plans to let his role sort itself out.

“I’m trying to control what I can,” Casas said. “It hasn’t worked out for me how I imagined it, but that doesn’t mean this year I can’t rewrite that script.
“I’ve had no wake-up calls my whole life. I’ve tried to stay ahead of the curve, and this is going to be no different.”
If Casas can stay healthy and put together productive full seasons, it would provide a major boost to the Red Sox lineup and roster flexibility. He burst onto the scene during his rookie campaign, finishing third in American League Rookie of the Year voting after hitting .263 with 24 home runs, 21 doubles, and an .856 OPS in 132 games.
A cartilage tear in his rib cage limited him to just 63 games in 2024, and the knee injury cut short his 2025 season after only 29 appearances.
Casas has the talent to be an impactful major league hitter, but injuries have slowed the start of his career.
“I definitely believe in my abilities and think they’re up there with the best in the game,” Casas said. “I’ve just got to be on the field and stay healthy to get that sample size.
“I’ve had good stretches as a major league player. I’ve had mostly bad ones. I see and know the habits of the best, and I think I’m right there with them. I haven’t shown it on the field yet, but mentally, I still believe I have the potential to be an All-Star-caliber player.”

Casas has been participating in baseball activities, but there’s still doubt he’ll be ready for Opening Day.
“I definitely want to make an impact from the first day,” Casas said Saturday. “That’d be 11 months from the surgery. So that would be a tight squeeze in terms of the relative overall consensus of how long it would take to recover from what I had injured, but it’s not unrealistic. I’ve talked to other players who have had the injury and they’ve said 11 months is very reasonable. So as of right now, not too sure. Not trying to get ahead of myself, but I do see myself progressing well enough to maybe get into some spring training games. We’ll see how that goes because that’s a benchmark as well.”
He said he’s increasing the volume of baseball activities, but doesn’t want to rush anything within his rehab.
“Right around the 12-month mark is typically when all activity is supposed to return to normal,” Casas said. “That’s for me to I guess decide in a couple months — how I’m feeling up at that point. But I like the way I’m progressing. I’ve met every benchmark that I’ve had to up to now. I don’t know if it’s a good thing or a bad thing, but I surprise myself a lot just expecting pain in certain exercises that I don’t have and I’m happy about that."
SORTING OUT THE LINEUP
With spring training less than a month away, the Red Sox still have work to do as they finalize their roster for the 2026 season. That uncertainty hasn’t stopped Cora from locking in one key lineup decision with Contreras expected to hit cleanup.
“I know Willson will probably hit fourth. I know that one,” Cora said Saturday at Fenway Fest at Fenway Park.
Contreras represents the most significant addition of Boston’s offseason. With first base a revolving door in recent seasons, the veteran slugger arrives as the club’s clear everyday option.
“Willson’s going to bring a lot,” Cora said. “He hits the ball hard. It’s a good at-bat. He drives the ball to right-center, but last year, he pulled the ball a little more than usual, which is awesome for us.”
While Contreras appears cemented in the heart of the order, the rest of the lineup remains very much in flux — particularly at the top.
Cora admitted he has no clear answer yet for who will lead off, with Roman Anthony and Jarren Duran both expected to be in the mix.
“I’m not there yet, to be honest,” Cora said. “Usually by this point, I have a pretty good idea what we’re going to do. But honestly, I have no idea. We have to wait and see what the roster is going to look like. A few positions are going to be battles, and that’s going to dictate what we do.
“For the first time in years, I don’t know how we’re going to do it.”
Outside of Anthony and Duran, there are few obvious leadoff candidates on the roster. Cora emphasized his desire to build a balanced lineup, alternating left- and right-handed hitters — even if the roster remains heavily left-handed.
“I still believe we’re very left-handed,” Cora said. “But at the same time, we were very left-handed last year and still scored runs. We just have to create balance — by trades, free agency, or developing guys. We’ll see where we’re at when we get to Fort Myers.”

Despite persistent offseason speculation, it does not appear the Red Sox are eager to trade from their outfield depth. That means Duran and Wilyer Abreu are expected to report to camp in February.
Breslow addressed rumors suggesting the club has shopped Duran or Abreu to reporters at Fenway Fest.
