Could also throw him into a trade. Lack of options limits his value but he's still young enough that he could have 4-5 good seasons as a viable back-up in MLB. Catching is just that thin/weak around the league (though you sure wouldn't know it watching the Dodgers).
Even the Braves, despite having last year's ROTY and three more years of Sean Murphy (who's making JT look good right now) have rostered Jonah Heim, Austin Wynns, Sandy Leon, Joey Bart, Chadwick Tromp and Jair Camargo this year. Several of those guys could have been Phllies (and one was a few years ago).
