How it plays

Every number is an index where 100 is league average. There is no such thing as one park factor — this park does different things to a triple than it does to a home run, and the only honest version is the whole row. Off 15,205 plate appearances in 2026.

	2026	2024-2026
Runs	96	94
Home runs	96	102
Triples	63	88
Doubles	95	87
Singles	97	96
Walks	111	106
Strikeouts	113	111
Value on contact	101	100
Expected on contact	99	98

How much of this is the park? Across 2022–2026, this venue's single-season value-on-contact index moved by ±0.9 points (a 2-point spread over 5 seasons). The league median is 3.0. Read a single season's figure with that much slack in it — the walls do not move, and the number does.

By the batter's side

Runs	94 RHB	96 LHB
Home runs	103 RHB	89 LHB
Value on contact	100 RHB	102 LHB

7,502 right-handed and 7,703 left-handed plate appearances — each side is half a season, so read these with at least the slack the combined figures carry — the band above is ±0.9 on twice this sample.

What FVR does about it

Every luck gap we measure at this park has −0.0010 subtracted from it, off 3,453 balls in play here this season. That is the number behind every board on this site, which is the only reason it is printed. It is not on the 100-is-average scale above: it is value on contact per ball in play, so it cannot be added to or subtracted from any index in this table. The two can even point opposite ways — Savant's runs index counts all offense, ours is only the residual against what the batted balls deserved.

The lore

American Family Field

The Brewers' home since 2001 has the only fan-shaped convertible roof in North America — and has twice taken in games other parks could not host.

The Roof

North America's only fan-shaped convertible roof can open and close in under 10 minutes above the diamond at American Family Field. The park opened in 2001, designed by NBBJ and engineered by Arup, replacing Milwaukee County Stadium. It opened under the name Miller Park; after the Miller Brewing Company's agreement expired at the end of 2020, a 15-year naming-rights deal with Madison-based American Family Insurance put a new name on the building.

The Brewers are the only major-league club it has housed, and the 2026 season is its 26th. The field is natural grass — Lo-Mo Kentucky bluegrass laid in 2009, yielding truer hops and fewer bad bounces than the original turf. Dimensions run 344 down the left-field line, 400 to center, 345 down the right. The 2002 All-Star Game ended here in a tie after 11 innings when both rosters were exhausted, a finish that drew enough criticism to change All-Star Game rules. Between innings, the Famous Racing Sausages — a mascot race that began as a dot-matrix scoreboard animation before it became a live event — run the warning track.

Borrowed Ground

The roof has also covered teams that had nowhere else to play. In April 2007, a snowstorm in Ohio forced the Cleveland Indians to move a home series against the Angels to Milwaukee. Seats were sold for ten dollars each, and total attendance for the three games topped 52,000. When Joe Borowski came in to close for Cleveland, the park played "Wild Thing" as a nod to Major League, and the Indians mascot slid down Bernie Brewer's slide after home runs.

In September 2008, Hurricane Ike's landfall in Houston relocated a Cubs-Astros series to the same field. Carlos Zambrano threw the first no-hitter in the stadium's history in a 5-0 Cubs win. Ted Lilly carried a no-hitter into the 7th inning the following afternoon.

The Plaza

Three iron workers — Jeffrey Wischer, William DeGrave, and Jerome Starr — died during construction when the Big Blue crane collapsed on July 14, 1999. A bronze statue called Teamwork stands on the home plate plaza.
