The day was March 6 when Tommy Joseph's season reached its highest point. He caught nine innings of a Grapefruit League game won praise from Roy Halladay and twice singled off Stephen Strasburg. The rest of the catching prospect's first full season in the Phillies system is a nightmare. The Phillies sent Joseph home for the rest of 2013 director of player development Joe Jordan said Thursday. The 22-year-old is still hampered by concussion symptoms. It is the third concussion of his young career. And it could force Joseph to play a position other than catcher. Jordan said the team is hopeful Joseph can remain behind the plate where his value is highest but the organization may talk about a switch before 2014 begins. Joseph acquired in the Hunter Pence trade last July played in just 36 games and hit .179 with a .514 OPS. When Joseph departed big-league spring training the plan looked simple. Joseph with a solid season could ascend to the majors in 2014 as Carlos Ruiz's heir. Now that path is decidedly less certain.
