Runner Breaks Up Double Play


 
We have all heard a base coach instruct a base-runner to "break up the double play". What do the umpires do when we believe that a runner actually did attempt to do this?

With bases loaded and one out, the batter (B1) grounds to the 2nd baseman. The 2nd baseman throws to 2nd base for the force out. The runner from 1st base (R1) slides out of the base path in an attempt to prevent/alter the throw to 1st base. The throw is made to 1st base, but the speedy B1 had easily beat the throw and is safe at first. At the end of playing action, one run had scored and runners are at 3rd and 1st base.

Since R1's slide did not prevent a throw to 1st base and B1 was easily safe at 1st base, is there any action for the umpires?

Call
On a force play, the runner must slide in a direct line between the two bases (NF 2-32-2f)The penalty for an illegal slide on a force-play slide is that both the runner and the batter-runner are out (NF 8-4-2).

So in the play below, both R1 and B1 are out and the inning is over.
