Thanks, all.
I posted this dilemma on the baseball site also. Concensus there, and here, is to SLOW DOWN and see the whole play.
To be slow and make the right call is always acceptable. (The alternative of fast and wrong would never be acceptable.)

P.S. I did hear the fan but I didn't react or even look up. It was a rather cold, windy day and perhaps that one comment just happened to get blown directly at me?
