Boston Red Sox second baseman Dustin Pedroia (knee) is not in Friday's lineup versus the Seattle Mariners.
Josh Rutledge is starting at second base and hitting sixth versus Mariners right-hander Yovani Gallardo. The Red Sox are likely just taking a conservative approach after Pedroia left early on Thursday with a sore left knee.
Pedroia is slashing .288/.366/.374 with a .326 wOBA in 188 plate appearances this season.
