An advancing base runner has a right of access along the base path. If a runner interferes with a fielder fielding a batted ball, the runner is out. If a runner intentionally interferes with a fielder or a throw to prevent a double play, both runners are out. The boundaries will be defined at the start of the game and enforced by both coaches . The orange safe bag is no longer in-play, once a play at first is over.
All further play is from the white portion of the bag.
If any part of the fielder touches the orange part of the safe bag, the runner is safe. If any part of the runner touches the white part of the safe bag, the runner is out. A tag out is legal at first. A batter running may touch the white part of the bag if there is no play at first. A batter who overruns first base may not be tagged out as long as they return directly to the bag, without starting a deliberate move towards second base.
