After a successful double steal attempt where a batter interfered with the catcher’s play, what is the umpire's call?

In the scenario described, after a successful double steal attempt where the batter interfered with the catcher's play, the appropriate ruling is that R2 is declared out for interference. This is rooted in the rules surrounding interference in baseball, specifically when a batter hinders or obstructs a fielder attempting to make a play.

When the batter interferes with the catcher trying to field the ball or make a play on a baserunner, the interference is recognized by the umpire, leading to the declaration of an out. In this case, R2, the runner who was stealing second base, is the one affected by the interference and is therefore ruled out.

The other options involve either R1, who is stealing to third base, being called out wrongly or suggesting that the play is dead or requires R1 to return to first base, which does not align with the consequences of the interference rule in this context. The ruling focuses solely on the impact of the batter's interference on R2's attempt to reach second base.
