If the ball becomes blocked due to offensive equipment not involved in the game.

Effect:
a. The ball is dead.
b. Runners are returned to the last base touched at the time of the blocked
ball.
c. If the blocked ball prevented the defense from making an out, the runner
being played on is out.

If a thrown ball enters the on deck circle (which the on deck batter has vacated) and contacts one or two bats that the on deck batter left there, do we have a blocked ball?

What if a thrown ball hits the batter's discarded bat?
