Full-count

[dani]

A closed fist should equate to zero balls or strikes. Half the time the pitcher can't see the fingers the catcher is putting down, so lets not worry about the in/outfielders.

Two closed fists raised should be reserved for situations where there are 0 balls and 0 strikes on the batter. An example would be the signal given after a pickoff move(s) prior to the first pitch being delivered to the plate, etc. The signal for three balls and two strikes should be three fingers raised on the left hand and two fingers on the right.
