Fairchild entered Saturday's game in left field for the injured Angel Martinez (foot) and went 0-for-2 in a 9-1 loss to Boston.
Fairchild saw his first game action in the majors since being called up Friday after Steven Kwan was placed on the bereavement list. Martinez, who was removed after four innings, underwent an MRI following the game. If Martinez is forced to miss time, Fairchild and the lefty-hitting Petey Halpin could form a platoon in his place.
