It can be cured...

Justin Amlung is a former walk-on for the University of Louisville baseball team.  Yet last year he pitched and won the last game of the season for the Cardinals.  Why would someone who could be trusted in such a situation be a walk-on, and not a scholarship player?  You can guess...when Amlung started, according to C.L. Brown of the Louisville Courier-Journal:

He classified himself as a ‘thrower' and not a pitcher.

The implication?  No, not that throwing isn't something real because of the use of quotes.  That he has now, finally, reached the Nirvana of being a true pitcher.  Congratulations, Justin.
