Was watching the MN vs. GA game and saw a ruling that had me puzzled. GA hitter (Hugo) at plate, runner on 1st, batter swings through pitch and hits catchers mitt with back swing. No steal or throwing attempt was made. Batter was awarded first base due to catchers interference according to announcers. Did the umpire just get this way wrong, or is there some specific rule that was applied? I thought MN coach would go ballistic, but she was calm about umps explanation which made me think there is some rule I am unaware of. I thought if the batter hits the catcher on back swing (weak interference) and no play is attempted ball was dead, and all runners must return if steal was made. If someone can educate me on this I would appreciate it.
