Batter Runner Hit By Thrown Ball

[ozzy6900]

R3 & R2, 0 outs

Witnessed this play while doing an evaluation on a JV umpire.

Batter hits a hot grounder to F3. F3 fields the ball but does not step on 1st. Instead, F3 sees R3 half way down the line and fires to F2. The ball hits the BR, in the running lane and the ball ricochets off the BR, over the head of F2 and to the backstop. R3 scores, F2 fires to F5 who misplays the ball and R2 scores. The BR stays on 1st.

1. Do we have 2 runs and a man on 1st?
2. Do we have any interference?
3. If the BR was out of the running lane, would we have interference? (better check your sources before you answer)
