Retractable Roof Policy
The Diamondbacks are required to follow all MLB policies in effect for retractable roof stadiums. In accordance with MLB policy, the following guidelines must be followed:
  • The decision as to whether a game begins with the roof open or closed rests solely with the home club.
  • If the game begins with the roof open:
    • It shall be closed only in the event of impending rain or other adverse weather conditions. The decision to close the roof shall be made by the home club, after consultation with the Umpire Crew Chief.
    • The Umpire Crew Chief shall notify the visiting club, which may challenge the opening of the roof if it feels that a competitive imbalance will arise. In such an event, the Umpire Crew Chief shall make a final decision based on the merits of the challenge.
    • Once the roof is closed during a game, it shall not be reopened.
  • If the game begins with the roof closed:
    • It may be opened when, in the opinion of the home club, the climatic environment has reached a level where fan comfort and enjoyment will be best served by opening the roof to the natural atmospheric conditions. Notwithstanding the foregoing, the following guidelines should be applied opening the roof during a game.
    • The roof may be opened only once during the game.
    • The Umpire Crew Chief will be notified at the commencement of the inning that the roof will be opened at the inning's conclusion.
    • The Umpire Crew Chief shall notify the visiting club, which may challenge the opening of the roof if it feels that a competitive imbalance will arise. In such an event, the Umpire Crew Chief shall make a final decision based on the merits of the challenge.
    • The opening of the roof shall only commence between innings.
    • The roof shall be opened in a pair of 2 minute, 15 second intervals; one interval at the conclusion of an inning and one interval at the conclusion of the next inning.
