The Boston Red Sox's hopes of seeing Triston Casas thrive this season have been dashed with his season-ending injury. With the team now in search of a replacement, manager Alex Cora is well-equipped with options from within the organization. Among the leading candidates is Rafael Devers, who is currently at designated hitter but could transition to first base. While some evaluators caution against asking him to switch positions mid-season, others note his versatility. Meanwhile, Marcelo Mayer, currently in Triple-A, stands out as a promising alternative, having the athleticism to switch to first base. Other options include Romy Gonzalez and Abraham Toro, who have seen time at first since Casas's injury. The team might also consider moving Trevor Story to first base or exploring outfielders like Wilyer Abreu for the role. Each choice carries its potential risks and rewards, but the Red Sox remain focused on maintaining offensive prowess in the wake of Casas's absence.
