Here's what the protagonist in a movie said (I'm typing what I heard, may or may not be grammatically correct): "Balls in your court".
In that phrase, the term 'balls' is shortened version of "Ball is..."
What I don't understand is that how do I write a grammatically correct sentence which has a shortened version of "Ball is in your court" that sounds like "Balls in your court"?
Is it "Ball's in your court" OR "Balls in your court" (as I mentioned above) OR is it something else?
I'm skeptical about "Ball's in your court" because that apostrophe would imply that it's about something related to the ball; it just feels out of place.
I hope the question is clear otherwise let me know. Thank you.
