Runner tagging on sacrifice fly

[FP26]

As you described, runners are able to anticipate the release of the pitch by watching the pitcher's arm circle. That enables them to get a moving head start prior to losing contact with the base and timed to the anticipated release. Do your coaches' signals provide that or are they equivalent to saying "go"?

Time seems to crawl when you're anxiously waiting for a signal to start...

Sorry if I was not clear. The third base coach will start moving his arm PRIOR to the ball being caught. Trying to help the runner time the jump. If the player is more comfortable watching the ball to time it herself, we will not force her to use our signals. It is her option.
