The Red Sox optioned Campbell to Triple-A Worcester on Friday, Jen McCaffrey of The Athletic reports.
Campbell has been slumping at the plate and struggling in the field recently, and Boston will send him down to Triple-A to get back on track. In his last 30 MLB games, Campbell slashed .176/.270/.231 with a 28.8 percent strikeout rate. His spot on the active roster goes to Wilyer Abreu (oblique), who is coming off the injured list.
