Wagner is out of the lineup for Sunday's game against the Orioles.
With the Orioles sending southpaw Trevor Rogers to the hill for the series finale, Wagner will give way to Nick Solak at designated hitter. Wagner had started the last four games against righties, going 4-for-8 with a double and four walks. The 27-year-old could have a fairly clear path to a strong-side platoon role until the Padres get Miguel Andujar (hamstring) back from the injured list.
