A player is NEVER forced to slide.

I must disagree with the other posters. There is no "must slide" rule in any league and under any set of rules. Some local leagues employ such a rule, but I think it is wrong.

In Little League, a runner is required to either slide or attempt to get around a fielder with the ball waiting to make the tag. They are not allowed to crash the catcher, or otherwise use contact to break a ball loose.

My opinion is that players still need to be responsible for their own bodies. There are times when sliding is not the wisest choice. There are times when sliding could injure a player. A late slide is usually responsible for serious injuries to the ankles. Under no circumstances should a player be required to slide.

Instead, players should simply be aware that they are expected to either slide or avoid contact. This puts them back into a position where they can do what is best for their own safety.

Don't force them to slide. Just make them slide or attempt to avoid contact.

Sincerely,
Jim Porter
