<P> Chase Field 's roof is opened or closed depending on the game - time temperature . When the decision is made to close the roof , it is left open for as long as possible before game time in order to keep the grass growing . Even when the roof is closed , the park 's windows allow enough sunlight to play in true daylight without overheating the stadium . </P>
