Catcher's interference

[Jay R]

OBR rules.

R3, 0 outs and a 1-2 count on the batter.

Batter starts to swing at the pitch when the catcher interferes with the BR (bat touches the catcher's glove). The batter misses the pitch and the ball goes by the catcher to the backstop. Do you automatcially call time and administer the catcher's interference or do you let R3 score on the passed ball, in which case the manager would have the option of taking the play as opposed to the interference?
