Donaldson is dealing with a jammed thumb and he is listed as day-to-day, Gregor Chisholm of MLB.com reports.

EDGE Analysis

Donaldson is out of the lineup Saturday due to some lingering thumb soreness after being jammed in Friday's game against the Red Sox. He is considered day-to-day, so there is hope that Donaldson won't miss much time beyond Saturday. Darwin Barney will slide over to start at third base for Saturday's contest.
