Sounds like the Reds are trying to give Homer a crashcourse in learning the art of "changing speeds". Dick Pole's rep with the changeup and Homer's need to learn it probably had alot to do with his hiring. But once the season starts, the "art of changing speeds" needs to be put on the backburner.
I am more concerned in getting Homer's breaking pitches up to a highly consistant level at this time. Save the offspeed development for a later date.
