Every game always has something new—minor plays, big events, whatever.
Among my favorites are completely unexpected events which get challenged or require rule checks to sort out how an unexpected event gets ruled by the umps or requires extended review, etc.
If you have one that comes to mind, share it here.
I’ll start with this rule check on a base runner who was thrown out at second, but then charged back to first base obstructing the play there:
Not only did the Mets lose this one, but it had two weird calls:

The first one is a great example of an outlier situation happening before and there being a rule which explicitly describes what happened:
“a catch is legal if the ball is finally held by any fielder, even though juggled, or held by another fielder before it touches the ground. Runners may leave their bases the instant the first fielder touches the ball.”
The obstruction one just reminds me of when someone learns a new word and then tries to use it every chance they get, except it’s an umpire trying to force a fairly obscure rule.
