Rupp is out of the lineup Sunday against the Padres, Todd Zolecki of MLB.com reports.
Rupp has been phenomenal at the plate in recent outings, having gone 8-for-23 with three home runs over the last seven days. However, he'll have the day off as the Phillies opt to start Carlos Ruiz behind the plate against San Diego. Rupp will likely return to the lineup Monday when Philadelphia begins their series against the Dodgers.
