1st/3rd base coach sitches

[eureka25]

I got two things that that I would like to hear how you guys handle with the base path coaches.

Sitch 1:
Foul Pop fly down the first base line. First basemen goes after the ball and the first base coach does not move a muscle. 1st basemen runs around the coach and misses the ball. Do you make a call here for a coach interfernce even though no contact was made ??? What is the fule sited ???

Sitch 2:
This happens all the time and I want to hear responses on how you handle the coaches mouths. Ball is hit down the line and the ball is foul territory - Coach yells foul well before the ball is dead or touched. Give me some good responses to come back at him with. On a side note - this really upsets me when a fellow umpire calls it foul way too early also.

Thanks,
Jeff
