PREGAME CRITERIA FOR SAFECO FIELD ROOF
The Club President, after consultation with stadium operations personnel and the Head Groundskeeper, shall determine the roof configuration for the start of the game. In his absence, a joint decision will be made by the VP of Ballpark Operations, VP Associate General Manager and Head Groundskeeper.
The following factors will be considered when determining whether the roof shall be open or closed at the start of a game, always keeping in mind that Safeco Field is considered an “outdoor” facility.
1. Fan comfort and their enjoyment of the game.
2. Current weather conditions (rain, temperature/wind).
3. Weather forecast for throughout the game.
While there shall be no definitive temperature standard used to determine roof closure, temperatures between 40-50 degrees at field level with strong wind gusts are generally considered uncomfortable for our fans. Under those conditions, particularly if there are threatening skies, closing the roof is a recommended policy.
IN-GAME ROOF MOVEMENT
The guidelines spelled out in MLB’s 2009 Bulletin D-16 shall apply to roof movement during games at Safeco Field with the exception of Paragraph B (Opening a Closed Roof): It is the policy of the Mariners that if a game starts with the roof closed, or if the roof is closed during the course of a game, it shall remain closed for the duration of the game.
It is also the policy of MLB and the Mariners that should it start to rain in the middle of an inning, the roof can be closed during play after proper consultation with the crew chief and the visiting club. There is no need to wait until the end of the inning.
