What is the difference between a run and a home run?

Answer 1

A run is a point scored by a team, whether it's accomplished by stealing home or trotting home after a walk with the bases loaded. There are many ways to score a run, and a home run is one of them. A home run can account for as many as four runs (if the bases or loaded) or as few as one (a solo shot).

Answer 2

The only difference is that a Grand Slam will score 4 runs on a single swing of a bat whereas just a solo Homerun will score only 1 run on a single swing of a bat.

Answer 3

A grand slam is a home run with runners on every base.
