Remember when Dwight Gooden charged the mound and PUNCHED PAT COMBS IN THE FACE?!
Doc sure does ... and tells TMZ Sports if there's anyone questioning his fighting ability, they need to watch that video!
Of course, the 55-year-old MLB legend is gearing up for a celebrity boxing match against 29-year-old comic Catfish Cooley on March 7 in Atlantic City.
Some people are concerned for Gooden since Cooley is a big dude who squats 600 pounds -- but Doc tells us HE CAN SWING, BRO!
