American Family Field park factors

American Family Field ranks 23rd of 29 on Savant's 2024 to 2026 run index at 94, and 2026 so far is at 96, close enough to the baseline that the park is behaving the way it has across 2024 to 2026. The most extreme number here is the triples index at 86, 15th lowest in baseball on Savant's 2024 to 2026 view.

Park factor history

Five single seasons and the 2024 to 2026 view Baseball Savant shows by default. Reading them side by side is how you tell a park that has changed from a park that had one odd year.

Statcast park factors for American Family Field. 100 is league average. The strikeout column reads from the hitter's side, so a number above 100 means the park suppresses contact.

The ballpark itself

Elevation is 597 feet, close to the 518 foot league average, so altitude is not doing anything here. Home plate points southeast toward centre field, at 129.0 degrees, which is what turns a wind forecast into a blowing out or blowing in read rather than a guess. The roof is listed as retractable in the MLB venue record, so the run environment changes with the roof call. Playing surface is grass. The average fence sits 372 feet from the plate, level with the league average, and the average wall is 6.9 feet high.

Measured fence distance and wall height from the Statcast park dimensions record for 2026, with the difference against the 30 park average in the adjacent column. Average wall height here is 6.9 feet against a league average of 9.7, and the average home run at this park travels 379 feet.

What it means for a bet

Totals

A genuine run suppressor, and the under is priced accordingly. The profitable version is usually the first five innings, where the park effect is strongest and the bullpen has not had a say yet.

Home run props

Home runs outrun overall scoring here by 8 index points. That is the signature of a park that gives up damage in bursts: quiet innings and then a three run swing. Home run props and team total overs read better than the game total.

Strikeout props

A strikeout index of 111 means the park is quietly adding Ks. A starter arriving from a contact friendly park is usually priced on his season line, not on tonight's venue.

Handedness

The home run index favours right handed hitters by 15 points (109 against 94). When a lineup is stacked the other way, the park is doing less for them than the headline number suggests.

Roof

With the roof open the run index is 98, closed it is 92, a 6 point swing. The roof decision is public before first pitch and the total does not always move with it.

Every index on this page is a 2024 to 2026 figure unless the column says otherwise, and all of it is league relative: 100 is average, not neutral in an absolute sense. Park factors describe the venue, not tonight's pitching matchup, and they are the starting point of a number rather than the whole of it.
