The best place to sit to try and find shade is in the corners and in the upper deck. The upper deck has good protection from part of the retractable roof even when it is open. Sitting on the upper deck and near the corners of the field will give fans the best chance at shade and are a good place to sit to stay cool in the hot Arizona weather (opt for seats in Sections 300-302, and 330-332 for some of the best shade at the ballpark).

And just be sure to avoid the right field seats at all costs, as these are the worst for getting the shade and are likely to be some of the hottest.
