Double Play

[greymule]

The only time you call them out for two runners on the same base without a tag is if the pitcher has the ball in the circle and is not making a play on the runners. Give everyone time to make a mistake and then call time and take the runner not entitled to the base off of it.

But you don't declare anybody out. In this very rare case, if nobody moves and the pitcher doesn't make a play, you call time and send the following runner back a base, at least in ASA. (I don't think the book deals with this situation, but that what I heard at a clinic.) I can't imagine this happening at anything above pee-wee level.

Purely theoretically, in OBR, if two runners were on 2B and the pitcher wanted to pitch to a batter, that is entirely legal. Of course, the following runner has to be careful not to pass the preceding runner. But technically play can resume, even with two runners taking a lead off 2B. Chances are you will not see this in the upcoming World Series.
