Singleton was optioned to the minors, as were the following players (optioned, reassigned, whatever):
Joe Sclafani, Jake Buchanan, Tyler Heineman, Michael Feliz, A.J. Reed, Eury Perez, and Cesar Valdez.
A couple of notes:
After a Spring in which he "hit" .125/.176/.292, Singleton's optioning combined with A.J. Reed - who I'm sure was sent down for Triple-A experience/service time considerations - leaves Tyler White as the short-term heir apparent to 1B and a virtual lock to start at 1B at Yankee Stadium next Monday afternoon.
I thought this was Jon Singleton's year.
