Yeah, you just signal or relay 4 to the umpire and the batter takes his base. The pitch clock is off to side of the on deck circle closer to the plate, looks ridiculous, I saw it on the MLB network. I don't mind the intent walk rule, and the batter having to keep a foot in the box, but this other s*** can be enforced by an umpire (catcher visits, speed between pitches, etc)
