This play brings us back to an interesting point, is it a good idea to use the fist pump for a strike signal, considering it is the same signal that is used for signalling outs. As evidenced by the play in question, there is no doubt that if the plate umpires strike signal was some sort of point to the right (or basically anything that didn't resemble a out call) instead of a fist pump (out call looking signal), we probably wouldn't be talking about this play.

The vocalization of "no catch" is a good idea, but I don't think that saying that can be relied upon. I like the idea of signalling safe because it atleast indicates that there was no catch.

Personally, I give a full fingered point out to the right without turning my head. On a caught third strike, I give the out signal. If a third strike is not legally caught (thanks Sal), I signal strike but not out. I feel that is the most proper way to do it. The runner isn't safe yet, or out for that matter. The signal just indicates what happened, a strike. My default manner of signalling gives me the least chance for error. No out signal, just a strike signal. (While I realize that the head turn strike call is expected at higher levels, with one or two umpires, I feel I can miss something if I do that, so I don't turn my head)

As this situation shows, too much can go wrong signalling strikes with a fist. IMHO. Your mileage may vary...
