Yankees infielder Jazz Chisholm backs up Red Sox DH Rafael Devers, who refused to play the infield when asked this season.

The Red Sox moved a reticent Devers from third base to designated hitter after they signed Alex Bregman, who’s now on the injured list. Then in May they asked Devers to fill in at first base when they lost Triston Casas to season-ending surgery. But Devers did not budge: He will only be Boston’s DH.

Chisholm’s own approach to position flexibility stands in sharp contrast. He admitted that he thought he was done with the third base experiment last season after the Yankees let Gleyber Torres walk as a free agent. Second base is clearly a spot he feels comfortable in, but the Yankees want to keep veteran infielder DJ LeMahieu there now.
