Tyler Barnes announced this morning that the roof will be closed. Apparently, MLB doesn't want it moved during the game, and cool temperatures are anticipated as the game goes on. What the Brewers do during the regular season is fine. If it gets cold, they close the roof. However, the Astros kind of blew this for everybody when they wanted to get "creative" about how they used the roof during their last postseason appearance. Given that the Diamondbacks also have a retractable roof, I'd bet that there'd be little or no fuss on their part if the roof were closed mid-game. On the other hand, if the Brewers were playing a series against the Cardinals, you can bet that there'd be a fuss.
