Park Factors

<< 7/24 July 25, 2025 7/26 >>

Last Updated: 1:35 AM

Hot weather is in store across most of the league on Friday with 8 out of 13 outdoor games expecting temps above 80° and 5 games above 90°. Some of the best weather is in The Bronx where the high 80s will be paired with 10 mph wind blowing slightly out to right field. Yankee Stadium is receptive to wind and the conditions on Friday make the short porch even more reachable than usual. Similar conditions are forecasted for Baltimore, although with single digit wind speeds.

Boston and Cincinnati are two of the top run-producing venues on their own, and they'll both get a boost from plus hitting conditions on Friday with temps expected around 90°. The additional runs at Fenway typically come from more hits inside the yard, but the park is rated positive for homers this evening as well. For GABP, it's all about the small dimensions as the positive run environment there is solely based on producing more home runs.

Oracle Park is back in action with its typical forecast. It will be in the high 50s in San Francisco with double-digit wind blowing out. Frequent readers of this page know that the out-blowing wind pattern occurs nearly every game at Oracle, but it doesn't translate to the field as expected. The park was built to neutralize wind and remains a bottom-five park for home runs each year despite the "always-out" forecast.

There's lots of rain in the forecast on Friday, although it doesn't appear that many games are severely threatened by a PPD. Those parks with delay risk are highlighted in pink below.

Similarly, the 18-foot-tall fence in center offsets the close distance to home plate. While the tall fences help neutralize homers, they are excellent targets for singles and doubles.+0.19+0.67+1.63+1.91

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.+0.33+0.27+0.76+1.18

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.
