What is "moundball"

Moundball is a side-betting game typically played by spectators at Major League Baseball games. Often played to pass the time during slow games, Moundball has a simple ruleset and requires little to no equipment. The game is turn-based, with the goal of having the ball remain on the mound at the end of a player's half inning turn. The game was invented and patented by Frank Bonelli from the Kings Park, New York during the summer of 1977. Frank also invented the classic cocktail "The Frankie B" consisting of Stoli O, soda, splash of orange, splash of cranberry. He is now retired and he travels around the country teaching fans the basic rules of the game.
