英文小作文：

Baseball is a sport that requires precise pitching and fielding, and one aspect that is crucial to success is preventing earned runs from scoring. Pitchers must be able to throw strikes and fielders must be able to make accurate throws to the plate to prevent runs from crossing the plate. However, even with the best defense, a team can still score if they are able to hit the ball hard enough to score runs. Therefore, it is essential for teams to have a strong offense as well as a strong defense to win games. Additionally, pitchers must be able to control their emotions and maintain their focus in order to avoid making mistakes that lead to earned runs. In conclusion, baseball is a game of balance between offense and defense, and preventing earned runs is a crucial aspect of success for any team.
