B int?

[tcannizzo]

Had an interesting (at least to me) sitch tonight in a 12-U rec game.

B2 at bat with R1 on 2B with no outs.
B2 swings and misses, ball pops out of F2 mitt and lands in between the feet of B2 who has been standing still in the batter's box.
R1 takes off on the misplay by F2.
F2 goes for the ball under B2.
B2 backs away to allow F2 to get to ball laying still in the RH Batter's Box.
F2 picks up ball and then does not make a play on R1 who is headed to 3B.
So, no call.

BUT, what if F2 picked up the ball as B2 was giving way to F2 and in the process hinders F2 making a play on R1 at 3B?

What should be ruled here?
By the book we would have INT on B2, but really?

This is eerily similar to the OBS discussion in another thread (other board) about a defender's act that causes R to overrun base and subsequently gets put out. Similar from an affect point of view.
