Another Balk play

[isneths]

If the interpretation serves me right, F1 can throw to 2nd to PO R1 who is running to second IF AND ONLY IF his initial motion does not carry him toward the plate.

I. E., F1 lifts leg straight up as R1 is going. As long as said motion goes toward second and not home, F1 is legal in the PO to 2nd.
