Within a very short space of time, twice, I have witnessed a well-respected long-term race-caller nominate the wrong horse in a close finish.
I acknowledge that race-calling is a particularly demanding job but equally, it is very disconcerting to those punters whose runner is being incorrectly called.
Perhaps it is time to give this "trouper" a gentle tap on the shoulder(NB. not NSW).

Cheers.
