Stephenson is out of the lineup for Sunday's game against the Astros.
It's likely just a standard rest day for Stephenson, who started nine straight games after being reinstated from the injured list May 2. The 28-year-old has enjoyed a good start to the campaign with three doubles, a homer and a .794 OPS through 36 plate appearances. Jose Trevino will step in to catch righty Chase Petty on Sunday.
