Rounders is a bat-and-ball game that originated in England and is often considered a precursor to modern baseball. It is played between two teams, typically consisting of nine players each. The objective is to score runs by hitting a ball and running around four bases arranged in a diamond shape. The game is played on a grass field, and the team in the field tries to get the batting team out by catching the ball or touching the bases before the runners arrive. Rounders is popular in schools and recreational leagues, especially in the United Kingdom and Ireland.
