Situation: LL Majors. No outs. Bases loaded.
Play: Batter/Runner hits a hard one-hopper towards shortstop. As the SS fields the ball Runner 2 (on 2nd) plows him to the ground and ball rolls away.
I think that it is a double play. Batter/Runner out, Runner 2 out, and Runner 3 (who crossed the plate) returned to third.
Result: 2 outs, runners on 2nd and third.
Am I correct?
Bonus points for citing LL Rulebook support.
Thanks!
