I was not impressed

[CecilOne]

BR hits grounder to SS, hustles to 1st. BU in position, SS muffs ball, finally picks it up and throws. BU judges that BR will beat throw, reacts too soon and starts to signal safe. BU realizes the throw gets there in time, stops signal, yells and signals out (third to end inning). Much yelling and complaining by offense team, including "once called safe, she stays safe"

Finally, BU says to offense coaches "yes, I was wrong to judge too soon and signal too soon, but the call is right, she is out".

Not impressed by (1) jumping the call, don't know about (2) comment to coaches. What do you think about (2)?
