How would you handle this?

This happed a few weekends ago. LL game: Top of first, runner on first.. batter hits a ground ball towards the first baseman.. ball deflects off his glove into runner.. I blew this call last year and called the runner out.. this year.. NO CALL.. One of the assistant coaches came out after the completion of the play to ask why the runner was not out.. I explained.. he walked away no problem.. as soon as the deflected ball struck the runner.. an over agressive parent would not shut his trap about how the runner was out because he got hit by the ball. I tried to ignore it.. but the man just got louder.. (after a pitch or two to the next batter) I called time and pointed in the direction of this man and yelled "quiet now".. the man shut his mouth for the rest of the game.. after this half inning the coach came up to me and said hey you made the right call.. went over to the "fan" and explained it to him.

My question is, should I have handled this guy differently... should I have gone to the coach and had him take care of this guy.. or just ignored it all together, even though I felt that it was distracting to both teams involved? Thanks!
