I've never seen this before. Umpires just spent 10 minutes during the game reviewing the rulebook. Bases were loaded. Infield was in. Batted ball passes the pulled in SS and hits the runner going from 2b to 3b. Field umpire 2 immediately calls dead ball. Then the 10 minute reading of the rule book ensues. Ultimately the umpires decide to call a "do over." The batter returned to the plate and continued her at bat at the same point in the count with the runners returned as well.
