It's a warm day across most of the league Sunday afternoon with half of the outdoor games above 80° and the rest above 70°. Coors Field is the top venue for offense where the high-altitude stadium is playing a bit more hitter-friendly than usual with mid-80s and low-end air pressure.

Some of the best hitting weather on Sunday is in St. Louis where the hot temps are paired with 10 mph wind blowing out to center. Busch Stadium is normally pitcher-friendly, but it will play close to neutral this afternoon given the conditions.

There's a decent amount of rain in the forecast this afternoon, including in Kansas City where Kauffman Stadium is rated the next best run environment behind Coors. The scoring boost in Kansas City typically comes from additional hits inside the yard as the huge outfield is difficult to clear even when conditions are good. It will be humid with wind blowing out for Blue Jays / Royals.

The small outfields in Chicago and Cincinnati present some of the best home run spots on Sunday with temps in the 80s expected at each. Both games are flagged for a possible rain delay.

The wind continues to blow in at Tampa, making Steinbrenner Field, not as appealing for home runs as it had been earlier in the summer. The open-air minor league venue has played noticeably different this season depending on the wind direction. The shallow right field fence is still one of the top home run targets in the league.

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