2 strike 2 outs
 

With a runner on first 2 strikes and 2 outs the batter checks his swing. R1 is running and thrown out. Do you allow the deffenese to ask for help on the check swing?

The Long Answer
 

Yes.

Yes. This could allow the defense an advantageous fourth out by preventing the batter from coming up the next inning.

Why wouldn't you?

A better question is why would they? The inning is over, unless i'm missing something.

I agree with everyone here, its great stratagy on the defense to get the batter out and keep him from coming up first the next inning.

You're missing something. See post #3: http://forum.officiating.com/basebal...tml#post677009

From a coaching perspective - Who is the batter? Maybe he's a "sure" out and I'd be happy to see him leading off the next inning.

That's not a reason to ask, it's a reason not to ask. :p

Exactly!

But then the question was why wouldn't one ask.

I was responding to Stu Clary's question, and that was not it.

We clearly agree that the defense might or might not have a reason to ask!

Do not allow the appeal
 

The defense made a play. The defense will not have a choice.

Ah-ha! Thank you.

Not according to FED interpretations..........

SITUATION 20: Two outs, R3 at second base. On a 1-2 pitch, R3 attempts to steal third base as the batter attempts to check his swing. R3 is thrown out at third base for the third out. The defense now wants to appeal the check-swing on B4 so that if he went around, he struck out and would not come back to bat in the next half-inning. U1 checks with the base umpire and U2 confirms that B4 did indeed swing at strike three. RULING: Since B4’s out is a “fourth” out, the defense may select the out which is most to its advantage. B4 is out for out No. 3 and the batter following him in the lineup will bat first in the next half-inning.

Actually on the check swing appeal the batter is the 3rd out and the throw unnecessary. But I would expect any good catcher to make the throw because he does not know what the result of the appeal will be.
