When is tagging used in softball?

Answer 1

You can tag a runner anytime but it's most important to tag a runner when it's not a force out play. When a baserunner runs to the next base without a runner behind him he must be tagged out before reaching base.

Answer 2

When the runner is not required to run to a base she/he must be tagged in order to be out. (like when stealing)

Answer 3

if shes sliding get her on the legs and if shes running tag her on the arm/chest
