An "at-bat" is a term used in baseball to describe a player's turn to hit the ball. It begins when the player steps into the batter's box and ends when the player either hits the ball, walks, strikes out, or is hit by a pitch. Each at-bat is recorded and contributes to the player's overall statistics. At-bats are important for evaluating a player's performance. The number of at-bats helps determine batting averages and other metrics, such as on-base percentage. Players like Babe Ruth and Ted Williams are often analyzed based on their at-bats to assess their hitting skills and effectiveness in games.
