Ok, I'll play the sucker:
B1 is "OUT!" caught by the second fielder who gained possession of the ball, which was still legally "in flight" (since it had not yet touched the ground or any object other than another fielder). This second fielder held the ball long enough to demonstrate control, and then voluntarily released the ball in the act of throwing it (even if it did go out of play).
My consolation is that Jim Porter really wanted to make this call, too, but piked out (I mean that in the nicest possible way, Jim

) - probably at the thought that Carl usually has something obscure hidden "up his sleeve" on such apparently simple P'sOTD.
Cheers,
