OBR rules, 16 year old summer ball, first and second occupied, batter goes to first on ball 3,the base runners advance without a play I'm yelling at the batter telling him its only ball 3 after they advance a base he comes back to finish his at bat.Thats when my partner makes the baserunners go back I'm thinking its up to the defense to know what the count is and they could have got a couple of outs. The coaches didn't argue the ruling, but I felt unsure it was the right call. It didn't make a difference, next pitch was ball 4, I would like to know the correct way to handle this.......Thanks Craig
