the pfitz sucks and it doesn't surprise me if there are problems like that.
what they should do is just renovate the park in phases, like harrisburg did. work on the side bleachers/concourse this year, during offseason, work on the grandstand/press box/dugouts.
There is no renovation that will fix its stupid orientation. Why on earth someone saw fit to placing a stadium in a way that the sun blinds the batter from down the LF line between 6 and 7 PM is beyond me
