Softball and baseball are mostly identical in lots of respects, yet you will notice some major differences between the two kinds of sports as you start to compare. And you should know the difference if you are planning on coaching entry-level softball if the experience you have has been for baseball, or vice versa. So the following will give you an insight in some of the differences:
the youth baseball program, particularly at advanced levels, features the pitching mound which pitchers throw from (younger levels might call for the hitter to hit the tee or just from the ball that is pitched from the coach). That is not the case for a softball game at all levels. Pitchers deliver the ball on the ground level with batters. The other main pitching difference will be that the softball pitcher delivers a ball in a secretive motion; the baseball pitcher can throw sidearm or overhand if they want. Using the best softball bats will help a great deal too.
