OBR Balk where does it say this?

[lc_huxter]

Situation. R1 only. RHP. Where does it say in OBR that he can not do the following.

RHP in the "stretch" picks his left leg straight up and turns his whole body while incontact with the rubber with his right foot. He then steps directly towards first base and throws the ball to first.


He do the exact same thing trying to pick someone off at 2nd or 3rd, but not 1st? I have also heard that a RHP can do the same thing as LHP.

Ofcourse we called this a balk and no one argued with us, but I would like to know where it says you can not do this in the OBR book.

Thanks
