The captain of an opposing team may challenge the legality of a bat after the batter steps to the plate but prior to the batter reaching base, and ask that the bat in question be compared to the NHSSC's list of ASA-approved single-wall bats. If the bat does not appear on the list in question, and does not indicate that it is a single-wall bat, the bat shall not be used and the team possessing the bat shall lose one point in the standings.

2.   If a ball travels on the fly (i.e. it does not hit ground, ceiling, fielder, etc.) and hits the rear wall uninterrupted below the “Green Monster” line, it is a ground rule double. If it travels on the fly and lands above the “Green Monster”, it is an automatic home run. If it is interrupted, (i.e. hits a fielder’s glove or ceiling) and then hits the back wall on the fly, it is a LIVE ball and all runners must advance as necessary.

3.   A ball hit off the ceiling is a live ball and MAY be caught for an out on the fly. As soon as it touches the ground, the runner(s) must be thrown out either by force or tag.

4.   A ball hit in foul territory may be caught for an out, either off the ceiling or on the fly. If a foul ball touches the side walls, it is a dead ball.

5.   If a ball becomes lodged in the netting, it will be a ground rule SINGLE.

incorrect batter reaches base and the error is caught by the opposing team the batter will be called out.  However, the opposing team must alert the umpire to the error before the first pitch is thrown to the next batter.

10.  If a catcher interferes with a batter’s swing the batter is automatically awarded first base.

11.  Home plate, bases, and foul lines are all to be considered fair territory.  Balls that land between the foul lines and then leave fair territory prior to first or third base will be considered foul, unless the ball is touched by a fielder while the ball is in fair territory.  Balls that land in fair territory past first and third base will be considered fair, regardless of whether the ball rolls into foul territory. 

12.  Pinch batters are allowed in case of injury.  However, the injured batter may not return to the game and the pinch batter will permanently take the batter’s place in the batting order. If no substitutes are available, the injured batter shall be called out.


Section Six – Running 

1.Runs are scored by advancing through the bases in order.

2.A runner will be called out if he interferes with a ball in play unless said ball is first touched by a fielder or the runner is on base, if he is forced to a base that is tagged by a fielder, if he is tagged directly by a fielder, if he leaves a base before a pitch crosses home plate, if he passes a runner who precedes him in the batting order, or if he leaves the base paths to avoid being tagged. 

3.Stealing is not allowed.

4.Runners advancing to first base must use the right “runner’s base,” while fielders may use the white base.  In the event of a ball hit to the outfield, and the runner intends to advance to second, he may round the base using the white base.

5.A runner may overrun first base without penalty.  However, the runner may be tagged out in the event of an aggressive move towards second base.

6.In the event of two runners finding themselves at the same base, the runner who touches it first is entitled to it.  The other runner is automatically out.

7.Runners may not slide headfirst while advancing a base.  However, a slide back towards an overrun base is allowed.

8.Each team may, without objection from the opposing team, utilize no more than one courtesy runner per inning. A courtesy runner is only allowed when the batter has stopped on first base, and only the last batter out from the previous inning may serve as a courtesy runner. Courtesy runners still occupy their spot in the lineup, and do not take the place of the batter for any purpose other than running the bases. The invocation of the courtesy runner rule must be announced to the umpire and the opposing team captain before the courtesy runner relieves the batter of his position on base. If the opposing team objects to the courtesy runner, the original batter must remain on base. Except for this provision, pinch runners are only allowed in case of injury.  However, the injured runner may not return to the game and the substitute batter shall take the runner’s place in the batting order.  If no substitute is available, the injured runner shall be called out.

9.On all plays at home, the runner may tag EITHER home plate or the “strike plate” as to avoid a collision. There is no automatic force play, and it is the runner’s responsibility to not interfere with the fielder.
