situation: man on 1st steals second while pitcher is in the set position. pitcher let's him have the base and then delivers the pitch - after the man on first has touched second. the pitch is fouled off by the batter. Does the runner have to go back to first?
this situation happens a lot in the first year of kid pitch (8 or 9 year olds). the call is usually if the base is touched before the ball is batted, he stays on second.
