Devers has only ever played third base and reportedly took issue with the Red Sox asking him to switch positions (designated hitter and first base) twice in the span of a few months.

The Boston Red Sox traded slugger Rafael Devers to the San Francisco Giants on Sunday in a deal that could shake up pennant races on both coasts.

The Red Sox reportedly felt that Devers didn't "live up" to the "responsibilities" of his hefty contract, which factored into the decision to trade him.
