too late to call infield fly?

Why would this be unfair?
Would you have allowed a run to score if a runner had crossed the plate when the IF wasn't called?
Now where if the fairness.

Answer this, what is the purpose and intent of the rule?
If you can understand the purpose/intent of a rule then you can apply it correctly.
This applies to all rules and all codes.

Purpose and intent = a correct enforcement of any rule.
