Ashley Marshall has a nice study at MiLB.com to create simple five-year minor league park factors. It’s not news that it is hard to hit homeruns in Savannah’s Historic Grayson Stadium. However, it turns out that relative to league average, Grayson Stadium with a HR park factor of .480 is the hardest stadium in which to hit a home run. Relative to league scoring, it is the second furthest from league average among actively used parks (behind only Sacramento).
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.
