Park Factors

Wednesday's slate features mild temperatures in the 60s and 70s for most outdoor games, along with possible rain at a handful of parks. The main exception is the pitcher-friendly Busch Stadium where it will be a dry 90° with light wind blowing in from center.

Coors Field sits atop the slate for the best run environment on Wednesday. It will be a slightly below average hitting day in Denver with temps dipping just under 70°.

Cool weather is expected in the Northeast this evening with Boston and New York featuring temps in the mid-60s. Hit-friendly Fenway Park is still rated positive for runs while Citi Field takes its usual place on the pitcher's end of the slate.

Those parks flagged for possible delay on Wednesday include COL, TB, WAS, KC, MIN, BOS, and NYM, with The Padres / Mets game in Queens appearing the most threatened. As is typically the case, the stormy weather across the slate is associated with higher humidity levels, which is better for fly ball distance (green "H"s in the chart below).

Similarly, the 18-foot-tall fence in center offsets the close distance to home plate.
