On June 4, 1974 the Cleveland Indians played the Texas Rangers and held a ten cent beer night at the field. A week before the game there had been a brawl between the two teams. The crowd got super drunk at the game and began misbehaving.
A father and son ran onto the field and mooned everyone in the bleachers and a woman ran onto the Indians deck and flashed everyone and then tried to kiss the umpire. Then a man ran stark naked and slid into second base as Grieve hit his second home run of the night.
The game took a turn for the worse when Leron Lee of Cleveland hit a line drive that hit Rangers pitcher Ferguson Jenkins in the stomach, causing him to fall down. The fans chanted for Lee to do it again. The fans got worse and started shooting fireworks into the Rangers’ dugout, throwing hotdogs at them, and spitting at them.
In the 9th inning, a fan tried to steal a Ranger player’s hat, making the Ranger fall. The manager thought the player had been attacked and ran onto the field with the Ranger players wielding bats.
The Indian’s fans came at them with knives, chains, and stadium chairs they’d ripped loose. The umpire called for a forfeit in favor of the Rangers.
