Happens a lot in college baseball. My son was playing in the Coastal Plains summer league. An opposing hitter hit a home run off my son's teammate and mouthed off to him as he rounded the bases. The next time the kid came up, my son was pitching and drilled him between the shoulder blades with a fastball. The batter screamed at the ump to throw my son out of the game for the intentional bean ball. The ump said, "the next time you hit a home run, keep your mouth shut". Old school baseball policed itself.
