Koss is out of the lineup for Sunday's game against the Padres.
Koss will take a seat after he went 4-for-18 with three runs and an RBI while starting at third base over the past five games. He'll cede the hot corner Sunday to Osleivis Basabe, who sticks in the lineup at a different position after playing second base in Saturday's 6-5 loss. Koss and Basabe could form a timeshare at third base until the Giants get Matt Chapman (abdomen) back from the injured list.
