Park Factors

<< 9/18 September 19, 2025 9/20 >>

Last Updated: 12:23 PM

Temperatures are in the 70s and 80s for nearly all the outdoor games on Friday, aside from Minnesota where it will be in the high 60s. Coors Field is once again the clear top park for offense with the high-altitude venue expected to play close to its season-long average.

The overall weather effect is just on the positive side of neutral Friday without any particular forecast having much of an impact. The most notable wind on the slate is in Tampa where it's expected to blow in from left at single-digit speeds. Steinbrenner Field has been highly receptive to wind this season, and the direction has proven to have an impact on the game even at lower speeds. The short porch in right should be just as accessible as usual.

An 80° day in Cincinnati would be an excellent forecast for home runs in years past. As has been discussed here, Great American Ball Park has been downgraded this season as home runs have been significantly fewer than expected given the fly balls hit in that stadium. Despite this, GABP is still rated on the positive side for homers on Friday.

Three parks are flagged for possible rain delay on Friday - CHW, MIN, and STL.
