The D-backs president and CEO, though, also wants to keep his customers happy, and when it comes to deciding whether the roof should be opened or closed, there is no way to please everyone.
After looking at the weather forecast for Monday which calls for temperatures in the upper 80's to low 90's with plenty of sunshine, Hall decided to close the roof.
"It's because of the temperature," he said. "I think if we did not have a sellout today and had plenty of inventory to be able to move people if they complained about the heat or sun, we would have it open. When it's sold out and it's 88-90 degrees, it's just a little too uncomfortable and we don't have anywhere to relocate them. If you're sitting on the first-base side, first of all, you can't see very well, and secondly, that sun coming right down on you is very uncomfortable."
The team plans on having the roof open for Wednesday's afternoon game because it is not a sellout and the team will be able to relocate fans who are uncomfortable.
"As long as we're consistent," Hall said. "We're going to push the envelope as much as we can, but fans can know what to expect."
The team has a roof hotline that fans can call to check on the status of the roof. The recording at 602-379-ROOF is updated daily.
