Charles Barkley -- I FIXED MY BUSTED ASS GOLF SWING!!!!

IT'S A MIRACLE!!!!!!!!

Charles Barkley -- owner of the WORST swing in the history of golf -- somehow found a way to ditch the remarkably awkward hitch in his stroke ... and now golfs like your average terrible player.

Miracle.

Barkley debuted the new swing at the American Century Championship tournament near Lake Tahoe ... and was APPLAUDED loudly by the crowd ... which was clearly expecting something more turrible.

FYI -- Barkley has finished dead last in the tournament on 5 separate occasions including last year.

Maybe there's hope ...
