Park Factors

It's a mostly neutral weather day on Friday with some of the league's top run environments playing close to their typical form. Temps in the 60s and 70s are expected for every outdoor game this evening with the exception of Sutter Health Park where it will be above 90° at start time. It's a dry heat in Sacramento tonight though (less than 20% humidity) which isn't as good for fly ball distance than if it were more humid. The typical breeze is expected to blow out to center field at slightly lower speeds than it has recently.

Coors Field takes its normal place atop the slate on Friday despite below-average hitting weather in Denver. The cooler 70° temps and low-ish humidity has the high-altitude venue rating slightly worse for offense than usual. Fenway Park is right behind Coors with 70° and light out-blowing wind expected in Boston. Both Fenway and Coors are excellent for runs via balls in play with neither relying on home runs to necessarily produce offense. Both venues happen to be flagged for possible delay/PPD due to rain this evening.

Great American Ball Park and Citizens Bank are rated positive for home runs on Friday despite neutral weather. Both venues have small outfields which naturally produce more homers without the help of the conditions. It's worth noting that GABP is being downgraded by the model this season as it's produced far fewer home runs than expected given the fly balls being hit in Cincinnati.

Cooler temperatures are expected in the Midwest this evening with the offensive environments in Minnesota, Cleveland, and Chicago all being dampened a bit by temps in the 60s.

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