Fastpitch softball is a competitive team sport played on a diamond-shaped field. It involves two teams, each consisting of nine players, who take turns batting and fielding. The game is played with a round ball and a bat, and the objective is to score runs by hitting the ball and running around four bases. The pitcher throws the ball at high speed, typically underhand, making it a fast-paced game. The rules of fastpitch softball are similar to baseball, but there are key differences, such as the distance between bases and the pitcher's mound. Fastpitch is popular at various levels, including youth leagues, high school, and collegiate competitions, with organizations like USA Softball and NFCA governing the sport.
