Although these aren't terrible seats overall, 133 is one of the sections you will want to avoid at PNC Park.
The left field foul pole is a little bit of an obstruction depending on which seat you purchase. Why risk it?

You're far from home plate and in the far corner of the ballpark. Did I mention these are bleacher seats? Which means the seating won't be nearly as comfortable as sitting in the infield or down the baselines.

If you get in the lower rows of this section, you won't have to worry about the obstruction.
