User: How do you play Baseball?
Assistant: Baseball is a game between two teams involving a baseball, which is a ball that is about 2 inches in diameter, and a bat used to hit the ball. Two teams alternate turns pitching and hitting the ball. The hitting team attempts to score as many runs by advancing through the four bases, prior to their team getting three outs during their turn hitting. The pitching team's objective is to prevent the hitting team from scoring runs. Games traditionally last 9 innings, with each team having the opportunity to both hit and pitch 9 times. The team with the most runs after 9 innings wins the game.
