Personally, I would send a tenner in the post to stick behind the bar for the guy as a way of an apology with a short note stating that you didn't mean to be unsporting and to have a pint on your dollar.
No need to do that, no matter what HE still missed the putt!
If you had not done it chances are the match would have finished the same anyway, you will never know though...
