Please refer to Commissioner's Bulletins regarding opening and closing retractable roofs.


It is the desire of the Milwaukee Brewers to have the roof open as much as feasible. The Brewers philosophy on the pre-game positioning of the roof and walls is to provide the playing and viewing of the game in the best environment possible.

The most current weather forecast thru the anticipated normal conclusion of the game is taken into account when the decision to have the roof and/or walls open or closed is made.

The umpire chief/crew is informed of the current weather information and the decision that was made as to the roof/wall pre-game position.

In general, in-game movement of the roof and walls at Miller Park will be utilized in the same manner as a field tarp would be used in an open-air facility.

If the roof/walls are open for the start of the game, adverse developing weather conditions would generally be the reason the roof and/or walls would be closed.

If the roof and/or walls are closed at any point before or during the game, an improvement in the current weather conditions, and/or adverse temperatures or high humidity inside the ballpark, will be the reasons to open the roof/walls. An unforeseen reversal of weather conditions would be the only reason for a closing of the roof/walls again under this scenario.

The designated Brewers staff to communicate the various roof/walls positioning to the umpire chief/crew would be the Vice President – Miller Park Operations and, as an alternate, the Head Groundskeeper, who also monitors the weather conditions.
