I saw the pictures and I am in agreement. Try not end up in the back rows of Sections 534-538 on the Promenade Level. Its right behind the left field wall.
For $27 dollars it might not bother you. It is possible to see the field. But if a ball is popped up or on its way to being a home run, you will have no clue until it lands. You will only be able to see ground balls.
Kudos to Andrew for checking that out.
