There are other kinds of hits, but these are the major ones. These hits can be made by many ways. For example; a single can come from a hit that travelled along the ground (called a "grounder") or that travelled in the air (a "fly ball"). A grounder can often be harder for the other team to stop than a fly ball. This is because when it moves along the ground it has more chance of hitting bumps and the glove or foot of the other teams player than it does if it moves in the air. There are also more ways in which hits can happen but these are the two major ways.
