Park Factors

Last Updated: 1:30 AM

Mild weather is expected on Thursday with temps in the 70s and minimal wind impact across the slate. Air pressure is on the high side at most venues, which is a factor that reduces fly ball distance.

Aside from the higher pressure, most of the variance on Thursday has simply to do with stadium differences between the parks, with the small outfields in Philadelphia and Chicago helping those venues rate positive for home runs. Overall, it's a fairly neutral slate of park factors tilting slightly in favor of pitchers.

The left-field corner is particularly deep while most of the outfield perimeter is closer than average. A 21-foot-tall fence compensates for the short distance down the right field line.-0.27+0.05+1.08+0.36
