Overview The American Association of Professional Baseball is a Major League Baseball Partner League, the top level of pro baseball outside MLB's farm system. Its clubs play across the Upper Midwest and Great Plains and into Canada, from Winnipeg and Fargo-Moorhead to Kansas City, Chicago and Milwaukee, over a 102-game season from early May to early September. One league deal covers league marks, its own broadcast and streaming platform, and assets in every member ballpark. On site League games are built as affordable family nights out, with fireworks, giveaways and in-stadium promotions. The ballparks include Impact Field next to O'Hare in suburban Chicago, Franklin Field outside Milwaukee, Wisconsin Brewing Company Park in Oconomowoc and Haymarket Park in Lincoln, and the league is adding a club in Blaine, Minnesota, at The Farm, a new sports and entertainment district. The All-Star Game and Home Run Derby, the playoffs and Opening Day are the league's marquee moments, and partners can carry their brand through all of them. Audience League attendance has topped 1.4 million for five straight seasons, the best average among MLB Partner Leagues. Fans split 55% men and 45% women; about a third are 25 to 39, almost as many are 40 to 59, and 14% are under 18. About 36% report household income above $100,000. AABaseball.com draws about 200,000 unique visitors a year, and league and team social accounts pass 600,000 followers. Talent and Influencers The league is a proving ground for players headed back to affiliated baseball. Seventeen alumni played in the majors this past season, five of them in their first call-up, and more than 65 have reached MLB overall, with nearly 500 player contracts sold to MLB organizations. Commissioner Joshua Schaub leads the league, and its Hall of Fame honors owners, managers and players, among them former big-league catcher Chris Coste. Game broadcasts and the league's social team turn those players into weekly content for fans across every market. Track record The broadcast footprint now reaches more than 70 million homes through FanDuel Sports Network, SI TV, Marquee Sports Network, NESN and others.
