So Sunday we are playing and the opposing team hits a deep ball down the right field line my right fielder turns to run after it and the Home plate umpire shouts Foul Ball, Foul Ball, Foul Ball, Let it Go, so my fielder lets it go. Apparently the field umpire pointed fair so the runner rounds the bases. After a conference its decided it was fair and the runner gets a HR out of it. An inning later there's a ball hit and the home plate umpire yells the same thing my fielder not taking a chance goes and gets it when she gets it in the umpire tells her she is wasting time and when he says let it go let it go. (yup this lead to a parent my team getting tossed not that I could blame him). Anybody have this issue ever happen to them? I feel like there has to be some sort of rule on this?
