The Boston Red Sox thought they would be better off with a happy clubhouse than a disgruntled Rafael Devers. A day after trading their erstwhile third baseman to the San Francisco Giants, Red Sox President Sam Kennedy told reporters on Monday night that Devers’ refusal to change positions made it untenable for him to remain with the team. The Red Sox sent the three-time All-Star to the San Francisco Giants on Sunday night for pitchers Jordan Hicks and Kyle Harrison and a pair of prospects. The move comes less than two years after signing Devers to a 10-year, $313.5 million contract.
