Reds star Trevor Bauer is taking his support for Joe Kelly to his feet ... rockin' "Free Joe Kelly" cleats for Cincy's game Wednesday -- and the tribute is pretty amazing!!
As we previously reported, Kelly is set to undergo a 5-game suspension as soon as he comes off the Dodgers' injured list ... and it's all because MLB says he threw at cheating Houston Astros players last month.
But, dozens of guys in The Show -- including Kelly himself -- think it's all B.S. ... saying Joe didn't actually hit anybody, and he really wasn't involved in the near brawl on the field either.
