How to say it...

[umpire99]

I had a play in the first inning of a game last night where a coach claimed that his player had hit the catcher's mit on his swing. When he asked my why I didn't call it, I said "he didn't hit the mit." Later, I go to thinking that it might have been better if I had said, "I didn't see him hit the mit." How should I have said it?
