Invented in 1895 version of softball called “Kitten Ball.” Game was invented to occupy the idle time of Minneapolis firemen. Regular games were played by the two first teams during the summer of 1895. Although the scores were high at first, the games were extremely interesting and closely contested. The first two teams to play the game were the Engine Company team and the Truck team. In 1913, the Minneapolis Park Board adopted the game officially for the park board playground and gradually grew in popularity, although it was called Diamond Ball instead of Kitten Ball.
