Arizona Fall League

The league's inaugural season was 1992, during which each team played a 54-game schedule that ended in early December. The divisions and teams that season were:

• Northern division: Grand Canyon Rafters, Scottsdale Scorpions, Sun Cities Solar Sox
• Southern division: Chandler Diamondbacks, Phoenix Saguaros, Tucson Javelinas

The league's first game was played on October 6, 1992, with the Grand Canyon Rafters defeating the Scottsdale Scorpions, 6–4.

Before the 1994 season, the Javelinas relocated from Tucson to Peoria, to limit travel distances to the Phoenix metropolitan area. All teams have been located in greater Phoenix since then.

Since 1995, when the Diamondbacks became the Desert Dogs, no team has changed its nickname. However, each team has changed its location at least once during its history. The most recent change was by the Desert Dogs, who moved from Phoenix to Glendale in 2013.

For the 1998 season, organizers rostered players onto each Arizona Fall League team from a single division in MLB:

In 2007, the United States national baseball team and China national baseball team played several games against AFL teams; both teams were later competitors in baseball at the 2008 Summer Olympics. In 2019, the Mesa Solar Sox participated in the Vamos a Tucson Mexican Baseball Fiesta in early October, facing teams of the Mexican Pacific League.

In 2019, the league adopted a new logo. In 2020, the season was cancelled due to the COVID-19 pandemic.

A number of future MLB All-Stars have had stints in the Arizona Fall League; over 300, per the league's website. These include David Wright (2003), Dustin Pedroia (2004), Andre Ethier (2005), Bryce Harper (2010–2011), Nolan Arenado (2011), Mike Trout (2011), Mookie Betts (2013), Aaron Judge (2014), Gleyber Torres (2016), and Ronald Acuña Jr. (2017). In 1994, Michael Jordan played for Scottsdale during his time away from the NBA. Similarly, former NFL quarterback Tim Tebow played for Scottsdale in 2016 during his foray into professional baseball.
