Acosta signed a minor league contract with the Rays on Thursday and will be invited to major league camp, Marc Topkin of the Tampa Bay Times reports.
Acosta was with the Rays organization last season, but played sparingly and elected to be a free agent after the conclusion of the season. He'll return to the team and act as no more than a third-string catcher while Justin O'Conner is sidelined with a back injury.
