Warm-up Pitches

[Paddy]

We only use the 5 pitches in the first inning and 3 pitches there after and don't time it.
But my question is how do you time it ?
I don't carry a stopwatch. Do you have a game clock that indicates seconds on the field that tell you that a minute has passed. Like they use at WC for the 20 seconds.

And this sounds very strange, first of all you call it at 50 sec. instead of 60.
Second a catcher doesn't need to throw down.
Third don't you need to make sure the batter and you are ready and call Play Ball before you can call the pitcher for not delivering on time ?
