Catcher calling a time out...

[Saltydog]

There's always the option of asking the coach 'So, ya gonna send him, 'cause I'd like to get on with the game'. This works best coming from Umpire, but works 'ok' coming from defense.
Option two, catcher walks down to third. Hands ball to third baseman. Walks back to plate and takes his postion behind plate. Pitcher mounts rubber and third throws him the ball. I think by LL rules if catcher is ready to receive and pitcher is on mound the runner has to be on the base. Pitch the ball with him off and he's out.
I'm sure someone will correct me if I'm wrong :-)
