Soderstrom will start at first base and bat ninth in Sunday's game against Atlanta.
The lefty-hitting Soderstrom has now started in three of Oakland's last four matchups against right-handed pitchers and appears to have displaced J.D. Davis as the Athletics' preferred option at the position. Soderstrom is still likely to occupy the strong side of a platoon at first base with either Davis or Aledmys Diaz.
