What the fungo is 'rag ball'? FOX Sports Detroit explained:
Rag ball is a drill using a softer version of a baseball called an Incrediball. A coach, in this case Omar Vizquel, stood about 25-30 feet away from the pitcher and sharply hit it to make the pitcher react quickly to catch it.
Sounds a little more safe than the same exact drill my college team would do with a real baseball. MFPFP.
Joba 'midge' Chamberlain won, of course.
