Running Start behind Third

[greymule]

In appeals, the OBR book speaks of tagging the runner or the base "missed or left too soon." It doesn't include "or at which the runner got a running start." (Of course, the "appeal" of BOO doesn't require a tag, either.)

However, that could be simply an oversight, and the BRD is carefully compiled. It's hard to believe that a running start has to be appealed, though.

I've wondered whether it's still a violation if the runner backs up behind the base to get a running start but then remains at the base (or runs partway to the next base and then retreats)?

Similarly, I was once called out when I tagged up on 3B on a long fly, and the 3B coach whacked my rear at the moment the outfielder caught the ball. Would I still have been out if I hadn't run home?
