3rd base coach contacts runner

[NCASAUmp]

I agree with Mike. A pet peeve of mine is to see or hear about an umpire who called a runner out for getting a high-five from their base coach on an over-the-fence home run. I mean, come on.

The only way I'd call the out in the sitch provided is if somehow, the collision DID help the runner. For example, if the runner rounded 3B with a wide path (no fat jokes, guys), and the throw came home. If the collision stopped the runner's progress towards home and allowed him to more easily get back to 3B, then I'm calling the out.

In all likelihood, these are rare cases, and most of them may not result in an out. It's your judgment as to whether or not the bump "physically assists" the runner. Not "touches," not "makes contact with." "Physically assists" is the correct terminology.
