What "clean hit" means in baseball

In baseball, a "clean hit" refers to a ball that is hit by the batter and lands in fair territory without being touched by a fielder. A clean hit can result in a single, double, triple, or even a home run depending on how far the ball travels. If the ball is touched by a fielder before landing in fair territory or is caught by a fielder before touching the ground, it is not considered a clean hit.
