What's The Call?

You are right there is a typo. It is R2 and R3 that are on 2B simultaneously.

But you can't invoke LBR, because it is only valid if a runner is not in contact with a base.

To another poster, don't assume that the offense was stupid. By forcing a play out at 2B, this gives R1 an opportunity to score. Especially if R2 and R3 split on the play.

The correct ruling is that F1 MUST make a play to resolve the incorrect runner on 2B (R3), but if no play is made after a certain amount of time, you kill the play and return R3 to 1B.
