Playing in St. Louis, the Cardinals began looking west for a place to move to in the 1980's. The team was tired of playing at Busch Stadium, also home of the St. Louis Cardinals (MLB). After the 1987 season, the Cardinals moved to Arizona, and Sun Devil Stadium. Prior to the team's first season at Sun Devil Stadium, more expansions were completed at the stadium. Over 1,000 seats were added, along with an athletic complex on the south end of the stadium, a scoreboard, and four video boards. In 1989, a three-story, 60,000 square-foot building was constructed atop the upper deck on the west side, that contains two 30-suite levels, a modern press box, and eight additional private suites. Today, Sun Devil Stadium has over 72,000 seats. The main grandstand is in the shape of a horseshoe. Additional seating is located in the south end zone. The video/scoreboards are located beyond the south endzone. Fans who attend games at Sun Devil Stadium receive outstanding views of the surrounding area. The Cardinals played their last game at Sun Devil Stadium on December 24, 2005. In August 2006 the team moved into University of Phoenix Stadium in Glendale, AZ. Arizona State University continues to play at Sun Devil Stadium.
