Batters Interference

Technically, runners always return to the base last touched at TOI. Very often, that's equivalent to TOP.

Note that with R1 and R3, with less than 2 outs you can have the following sequence of events:
1. R1 attempts to steal 2B.
2. BI as F2 throws to 2B.
3. R3 attempts to steal home.
4. the throw to 2B retires R1.
5. R3 scores.

Because R1 is retired, the batter interference is ignored and the run scores. The defense does NOT have an option here (as I had a coach once ask). The batter will resume his time at bat.
