The visitor's bullpen at Minute Maid is difficult to see as it is behind the left-center field wall. It can only be seen through the outfield wall, so there are no sections that get a particularly good view of it. The best option would be to sit in the Crawford Box in section 100 because then you may be able to look over your shoulder and through the wall into the bullpen.
