This is pretty damn freakin' awesome ... Charlie Sheen just delivered the most epic pump up video in Cleveland Indians history ... going full Ricky "Wild Thing" Vaughn fire up the tribe faithful.
Sheen -- who played Vaughn in the epic 1989 comedy -- just donned his old CLE uniform complete with the signature horn-rimmed glasses while screening the movie in his home.
Watch what happens next ... and try not to get PISSED that Major League Baseball didn't let this guy throw out the first pitch.
