What is ground out in baseball?

Ground out is a type of out in baseball when the batter hits the ball and it rolls along the ground without leaving the infield and a defensive player catches the ball and throws it to a teammate covering first base before the batter can reach the base. This results in the batter being out and not being allowed to continue his turn at bat. Ground outs are a common way for pitchers and defense to get outs in baseball and can be caused by a variety of factors such as poor batting technique, good defensive positioning, or a well-placed pitch by the pitcher.
