Soccer announcer's cry after a goal

ITSIN

Think of what a commentator might shout when the ball crosses the line—it’s a quick, excited phrase that sounds like it’s confirming the score. The answer is a contraction often heard in sports broadcasts.

This clue plays on how a soccer announcer might excitedly shout "It's in!" after a goal, but squished together as "ITSIN." The wordplay relies on hearing the phrase as one continuous word rather than separate ones. It’s a common crossword trick where spoken language gets condensed into a single answer.
