Reading this thread over and wanted to introduce new info. Most readers have read about a new mechanic for a third strike not caught. Signal safe and verbalize no catch. Others disagree that a new signal is needed or that the new mechanic just hasn't gained universal acceptance.

I wanted to introduce a new and possible alternative. Hold 3 strikes up high with pinky ring and middle finger to alert both benches of the call and verbalize no catch. Let the resulting action lower your arm. It avoids the awkwardness of the safe signal after a strike. I like it.
