So leftfield/3rd base line is generally out of the sun for 12:30 games? I was just curious because it looks like that area faces East but maybe the right field upper deck cuts out the sun?
Well you need to sit fairly far back in the lower deck. My seats in 312 are always in shade, so I am presuming the entire 300 level down the 3rd base line is also shaded regardless of time of day. 200 level ought to be too, though it's possible the lower few rows may not be at first.
(however, be wary of the last couple of sections down towards the corner, the shade comes from the upper deck and roof which ends, I recall the last section in 300 level towards the LF foul pole can be in the sun)
