From THIS year's repertoire of fields?
Hmm...
1) Green River CC (bad everything)
2) Lynnwood HS (bad lighting at night, horrible infield, short dimensions)
3) Chief Sealth HS (bad location, infield usually not prepped)
Not in my list of worst fields, but a field I was very UNimpressed with, especially after all the hype, was Steve Cox field. The infield and mound are the only nice parts of the place...the dimensions are short, the outfield grass is lumpy and uneven, the dugouts are TINY...etc.
