What happens if R1 has touched second base when F6 throws the ball into dead-ball territory, but B2 has not touched first?

In this scenario, R1 has legally touched second base when the ball is thrown into dead-ball territory, causing a play to be ruled dead. When a ball goes into dead-ball territory, the runners on base are awarded the bases they have legally touched at the time of the throw.

Since R1 has successfully reached second base, he is awarded home plate as part of the dead-ball rule, which allows for the advancement of runners. However, B2 has not yet touched first base, which means he cannot advance as far as R1 can. Consequently, B2 is allowed to advance to first base as part of the ruling on the dead ball.

This ruling aligns with standard baseball rules that dictate how runners advance during instances of dead plays while also considering the position and actions of the runners at the time the ball went dead.
