Clinton Yates explains why he is surprised Rafael Devers is refusing to play first base for the Red Sox. "I know I'm a ballplayer, but at the same time, they can't expect me to play every single position out there. Devers said he spoke with Red Sox chief baseball officer Craig Breslow about the prospect of playing first in Casas' absence. I would like to think that he knows that changing positions isn't easy," Devers said through Red Sox interpreter Daveson Perez. Asked about changing his mind in the event the Red Sox receive little production from the current group of first basemen, Devers reiterated that he's a full-time DH.
