In reply to:

That was a good get" is an example of noun verbing, one that sports commentators seem to like. Then I checked Merriam-Websters online dictionary only to find that it lists "get" as a noun with one meaning being "a return of a difficult shot in a game (as tennis)". I haven't researched it further, but I'd bet it originated from nouning a verb. There are probably a lot more like it.

A try in rugby, perhaps? As I understand it, in the early days of the game, when a player crossed the opposition's line and dotted the ball down, he was allowed to try to kick a goal, hence "a try".
