It will be an arduous rehab for Boston Red Sox first baseman Triston Casas.
The 25-year-old is out for the season after undergoing surgery for a ruptured patellar tendon, which he sustained in early May while trying to beat out a chopper back to the pitcher.
One awkward misstep cost Casas his season and could affect his offseason routine. Here is what Casas had to say on the injury, via Chris Cotillo of Mass Live:
Triston Casas described this rehab process as “living his worst nightmare.” He is targeting Opening Day and his doctors believe he’s going to make a full recovery. Described the injury as feeling like his knee was “hit by a sledgehammer.”

The Red Sox have tried to patch the loss with guys like Romy González, Abraham Toro, Nick Sogard, and even Kristian Campbell, but none of them represent Casas’ upside.
However, for as much talent as Casas possesses, he is also no stranger to significant injuries. Casas has played 100 games just once since becoming a full-time Big Leaguer in 2023, when he appeared in 132 games. Just last summer, Casas was out for an extended period with torn cartilage in his rib cage and was limited to 63 games.
Now, he faces perhaps his greatest challenge yet.
Hopefully, Casas can make a full recovery for Opening Day 2026 and rediscover some of his 2023 momentum. That campaign saw him bat .263 with a .856 OPS, a 129 OPS+, 24 home runs, and a third-place finish in the American League Rookie of the Year vote.
This year felt like Casas was still trying to find that groove as he struggled mightily at the plate. Through 29 games and 99 at-bats, he had a .182 batting average, a .580 OPS, a 63 OPS+, and three home runs.
Health is the key for Casas, but he also needs to produce to grow into the franchise first baseman Boston so desperately needs.
