Casas (knee) conceded Monday that he won't play in any Grapefruit League games, Tim Healey of The Boston Globe reports.

EDGE Analysis

Casas had hoped to play in some spring training contests before the schedule concluded, but he will run out of time. He has yet to do any baserunning or sliding, and a clearer timetable for his game readiness won't be available until he checks off those boxes. Casas is working his way back from patellar tendon surgery on his left knee, which he underwent back on May 4.

Casas said recently that he has yet to test out his surgically repaired left knee with running or sliding, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Casas believes he will be ready to play "for some affiliate" Opening Day and doesn't rule out the possibility that it could be with the Red Sox, but it's unlikely. His rehab from patellar tendon surgery has come along well, but the 26-year-old still has some boxes to check before being cleared to play in games. With Willson Contreras set to man first base, the Red Sox can afford to proceed with caution with Casas. When Casas is ready to return to the big club, he will be in the mix for starts in the designated hitter slot.

Casas (knee) will be doing individual drills when the Red Sox have their first full-squad workout Sunday, Ian Browne of MLB.com reports.

EDGE Analysis

He'll be taking part in drills similar to the rest of the team. For the first time in three seasons, Casas does not enter camp as the primary starter at first base, as offseason trade acquisition Willson Contreras will handle the position. That leaves designated hitter as a potential landing spot for Casas once he's healthy, and he could provide a boost to a lineup that, on paper, lacks power. Any of Boston's four main outfielders could also slot in at DH, however, and Masataka Yoshida will be in the mix as well. Casas, who is recovering from May 2025 knee surgery, isn't expected to be ready for game action by Opening Day.

Casas (knee) said last week that being ready for Opening Day would be a "tight squeeze," Tim Healey of The Boston Globe reports.

EDGE Analysis

Casas added that doctors have told him a typical recovery from patellar tendon surgery is 12 months, which would point to him being ready for his season debut around May 1. The first baseman has been rehabbing at Boston's spring training facility in Florida this offseason and hopes to play in some spring training games. The Red Sox traded for Willson Contreras in December to take over at first base, so they can proceed cautiously with Casas' rehab.

Casas (knee) agreed to a one-year, $1.61 million contract with the Red Sox on Thursday to avoid arbitration, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Casas' 2025 campaign was disappointing, to say the least, as he slashed just .182/.277/.303 across 112 plate appearances before suffering a season-ending knee injury in May. His path to regular playing time at first base has seemingly disappeared as well, following the Red Sox's acquisition of Willson Contreras (shoulder) from St. Louis in December. It's worth noting that Casas has minor-league options remaining, so the team may decide to send him back to Triple-A Worcester if his struggles continue into spring training.

Casas (knee) could begin the season at Triple-A Worcester following Boston's acquisition of Willson Contreras (shoulder), Jen McCaffrey of The Athletic reports.

EDGE Analysis

Casas is working his way back from surgery to repair a ruptured left patellar tendon and could be ready to go Opening Day. However, with Contreras added to the mix, the Red Sox could choose to proceed cautiously with Casas, who has minor-league options remaining. A trade of an outfielder (likely Jarren Duran) could allow both Contreras and Casas to play regularly between first base and designated hitter, though Masataka Yoshida also looms as a DH option. A clearer plan for Casas should be revealed during spring training.

Casas (knee) has been at Boston's training facility in Fort Myers since the end of the regular season, Lauren Campbell of MassLive.com reports.

EDGE Analysis

It's unclear the type of activity in which Casas has been engaged, but Red Sox manager Alex Cora continues to have faith in the young first baseman, who was limited to 29 games last season. "That's great for a young guy to know what he needs to do to compete," the manager said. "He's done that. Hopefully we can get him heathy." The shortened 2025 season was the second consecutive one for Casas, who was limited to 63 games in 2024 due to a fractured rib. Casas is not a lock to return as the starting first baseman, and the Red Sox are rumored to have interest in free agent first baseman Pete Alonso.

Red Sox chief baseball officer Craig Breslow on Monday would not commit to Casas (knee) being the team's starting first baseman next season, Christopher Smith of MassLive.com reports.

EDGE Analysis

Breslow also noted that while Casas is "doing really well" in his recovery from surgery in May to repair a ruptured patellar tendon in his left knee, he could not guarantee the 25-year-old will be ready in time for Opening Day. If healthy, Casas is the heavy favorite to break camp as Boston's primary first baseman, but the Red Sox are keeping their options open at this early juncture of the offseason. Injuries have limited Casas to just 92 games over the last two seasons, and he slashed only .182/.277/.303 across 29 contests in 2025 before his knee injury.

Casas (knee) will be off crutches in two weeks and expects to be ready for Opening Day next season, Jen McCaffrey of The Athletic reports.

EDGE Analysis

Casas spoke to reporters Tuesday for the first time since he underwent surgery a month ago to repair the ruptured patellar tendon in his left knee. He will spend most of the summer rehabbing at Boston's spring training complex in Florida.

The Red Sox transferred Casas (knee) to the 60-day injured list Saturday.

EDGE Analysis

Casas underwent surgery in early May to repair the ruptured patellar tendon in his left knee and will aim to return in 2026. The move corresponds with the Red Sox selecting Marcelo Mayer's contract from Triple-A Worcester while placing Alex Bregman (quad) on the 10-day injured list.
