Willson Contreras Trade Creates Uncertainty for Triston Casas' Red Sox Role

The Boston Red Sox' acquisition of Willson Contreras has created uncertainty for Triston Casas' future with the club. Contreras is expected to be the primary first baseman, potentially sending Casas, 26, to Triple-A to shake off rust after an injury-plagued two seasons, including a ruptured patellar tendon that limited him to 29 games last year. Casas, who still has minor-league options, could eventually split first base and designated hitter duties with Contreras. His current trade value is low due to his recent injury history and lack of production.
