The stadium was built in 1968 and holds 9,558 people, making it the oldest and smallest stadium in the Cactus League. The stadium underwent an extensive $20 million renovation from 2002 until 2006 and was rededicated on March 3, 2006. The renovation included the main stadium, the Major League Fields and the Minor League Complex on site. The Arizona Sports and Tourism Authority, a municipal corporation charged with funding renovations of Cactus League stadiums throughout Maricopa County, funded $12 million of the renovations.
The Angels and the city government announced an agreement in May 2021 to keep the team's spring training in Tempe through at least 2035. The deal includes extensive renovations of the stadium and the surrounding complex, including a new home clubhouse, team offices, a team store and an outfield concourse.
