Zunino is managing a left shoulder injury and could be placed on the injured list, Marc Topkin of the Tampa Bay Times reports.
The specifics and severity of the injury remain unknown, but Rene Pinto is joining the team in Minnesota on Friday for depth behind the plate. Zunino is 2-for-24 with nine strikeouts over his past eight contests, though it's unclear how much of a factor the shoulder issue has played in his recent struggles, Francisco Mejia should work as Tampa Bay's No. 1 backstop if Zunino indeed lands on the shelf.
