Wagner is out of the lineup for Wednesday's game against Atlanta.
Left-hander Martin Perez is on the bump for Atlanta, so the left-handed-hitting Wagner will head to the bench while the Padres go with Fernando Tatis at second base and Miguel Andujar at designated hitter. Since being called up from Triple-A El Paso on June 9, Wagner has staked his claim to a strong-side platoon role by producing a serviceable .276/.432/.310 slash line over 13 games.
