8.3.5 SITUATION J:
R1 is at second when B2 hits to F6, who tries to tag R1 but misses. F6 then overthrows first into dead-ball area. R1 remains at second, but B2 has touched first at the time of the throw.
RULING: Because it was the second play by an infielder, R1 is awarded home, and B2 is awarded third.
