Photographer's Areas
The ball is "in play" if it hits any of the railings defining the photographer wells and bounces back onto the playing field. The vertical rails in the middle of the wells are considered in the wells and are out of play.
Ball Hitting Roof Trusses
A batted ball hitting a roof truss in fair territory shall be judged fair or foul in relation to where it lands or is touched by a fielder. If caught by a fielder, the batter is out and base runners advance at their own risk.
A batted ball hitting a roof truss in foul territory is a foul ball, regardless of where it lands or is touched by a fielder. If caught by a fielder, the batter is out and the base runners advance at their own risk.
Outfield Area
The hand-operated scoreboard in left field is part of the left field fence. A ball must clear the scoreboard (defined by yellow horizontal line) to be a home run. If a batted ball hits the cyclone fence under the scoreboard and above the padded wall, and the ball lodges behind the padded wall, it shall be ruled a ground-rule double whether it lodges behind the wall on the fly or on a bounce.
The ladder and the handle attached to and to the right of the scoreboard are beyond the padded wall. A fly ball striking either the ladder or handle shall be ruled a home run.
Dugouts
A ball must enter the dugout to be considered a dead ball.
Movement of Roof
If a game is started with the roof closed, it may be opened when, in the opinion of the home club, climactic conditions warrant such opening. However, roof may be opened only once during a game and shall commence only between innings after the umpire crew chief has been notified. Prior to opening of roof, the visiting club may challenge the opening if it feels a competitive imbalance will arise. The crew chief will make a final decision based on the merits of the challenge.
If a game is started with the roof open, it may be closed during the game. The decision to close the roof shall be made by the home club, and may be made solely for the comfort of its fans. Play will continue during roof closure if possible. However, the umpires have the right to stop play during this process if they determine it is necessary to do so.
These policies may be modified from time to time as more experience is gained with the roof and its impact on play.
