Interferance?

[mcrowder]

I would not keep the ball live. Once the BR picked up the ball intentionally, I have a dead ball. I forget the rule reference, but I believe somewhere near the rules regarding balls that get lost in an offensive jersey, you'll find enough reasons to call this ball dead the instant the offense controls it.

He's not out on interference, for all the reasons stated above. But the ball is no longer live (so no further play at 1B or anywhere else - nothing to interfere with).
