Rupp is not in the lineup Wednesday for the second straight day, according to CSN's Jim Salisbury.
Rupp has been in a prolonged slump at the plate that has dropped his average from .277 on Aug. 14 to .259 as of Wednesday, so manager Pete Mackanin decided to give him back-to-back days off for the second time in a week. A.J. Ellis will start behind the plate again Wednesday in Rupp's place.
