Hot weather will return for most games on Friday with 8 out of 13 outdoor venues expecting temps in the 80s and 90s.

Some of the best hitting conditions are in Minnesota where it will be 90° this evening with low air pressure for Royals / Twins. Heat and low pressure are good for offense as both help the ball carry a bit farther. Similar weather is expected in St. Louis as the Cubs and Cardinals will enjoy 90° at start time. The normally pitcher-friendly Busch Stadium is playing close to neutral as a result of the good conditions.

Rate Field in Chicago is one of the top parks for home runs this evening as the upper 80s make the small outfield more vulnerable to the long ball. Venues with closer fences are more sensitive to temperature as the extra few feet of carry is more likely to turn a flyout or double into a homer.

It will be cooler on the East Coast on Friday where Yankee Stadium will get temperatures in the 70s with air pressure at the top end of the spectrum. The high pressure and slightly in-blowing wind have the venue rated neutral for home runs and negative for overall run scoring.

The entire left side is deeper than average and the 15-foot-tall fence in right further complicates things for hitters.

Straight-away center is close to home plate but extends to an extremely deep right-field gap.
