Tagging up after a time out is called

[LeenieK]

The coaches of our 13-15 yr old baseball team have had this question all year. Umps can't tell us the answer...Runners on base...our coach calls time-out to talk to the pitcher. Their runners do not tag up after the time-out. Rule book says they must re-tag before the ball is pitched but doesn't tell us how to get the runner out. Our question is...What is the proper way to get the runner out? Does blue just call him out after we call attention to the fact he didn't tag? Do we throw the ball to the base he was on and tag it? Tag the runner??? What??? Does anyone know officially? Thanks all!
