Funny you should mention that, because that's exactly what caused me to find this rule in the first place. 2 years ago, bottom of 7, we're up 1...2 outs, opponent has runner on 3rd. Batter puts up his hand, steps out of the box...and a coach from the dugout yells "Time" loud enough for our CF to hear it. Pitcher stops...ump calls balk and tieing run scores. Hit on the next pitch and we lose. Ump had no idea he had blown it.
