4, 2,1 and are great but I loved the one that the guy hits the catcher first and goes after the pitcher. Then he ends up fighting with the entire infield.
My number one would have been the Pete Rose and Bud Harrelson fight from the 1973 NLCS where Rose slid hard into Bud and then a fight broke out. The game was almost called because the fans started throwing stuff on the field
Also remember the $0.10 beer night in Cleveland where the whole stadium poured onto the field and starting fighting with the players.
