The Phillies have agreed to acquire standout catcher J.T. Realmuto from the Marlins for catcher Jorge Alfaro, right-hander Sixto Sanchez, left-hander Will Stewart and $250,000 in international bonus slot money, sources told MLB.com on Thursday. The deal, which is pending the completion of physicals, has not been confirmed by either club. The Phillies were able to draw from a deep farm system to agree to the deal, with the 20-year-old Sanchez ranked as their top prospect by MLB Pipeline (27th overall).
