Timing of Score - No Tag Up

[marvin]

The CCA softball umpires manual (college softball) does have the timing play signal in the section on umpires to umpire signals.

The reasoning:

"This alerts all umpires to the possibility of a time play and verifies that all umpires are aware that there are two outs."

I remember years ago this signal being taught in ASA umpire clinics (but I have not done ASA softball recently).
