A home run is a term used in baseball to describe a hit that allows the batter to round all the bases and score a run without stopping. This typically occurs when the ball is hit over the outfield fence, making it impossible for fielders to catch it. Home runs are exciting moments in a game and can significantly impact the score. There are different types of home runs, including solo home runs, which score one run, and grand slam home runs, which score four runs when the bases are loaded. Players known for hitting many home runs, like Babe Ruth and Barry Bonds, are often celebrated for their power and skill.
