As far as other Mets' full-season affiliates, St. Lucie is the second-most offensive friendly park in the pitcher-friendly Florida State League, Binghamton is a fair park in a fair league and Las Vegas is an offensive park in an offensive league. Only Abuquerque, Reno and Colorado Springs are better for offense than Vegas among PCL parks.
Marshall has a great note about the pitching leaderboards in the two AAA leagues, the PCL and the International League (IL):
In the PCL, strikeout leader John Ely of the Isotopes had the lowest ERA (3.20), and only seven qualifying pitchers posted a sub-4.00 mark. Back in the IL .... the top 21 pitchers by ERA all had marks below 4.00.
