Sloan Park is an American baseball park in Mesa, Arizona, that opened in 2014. The primary operator is the Chicago Cubs and the ballpark serves as their spring training home and is also the home of the Arizona League Cubs of the Arizona League and the Mesa Solar Sox of the Arizona Fall League. Sloan Park was built and paid for by residents of the City of Mesa, approved by ballot measure. It was primarily built to house spring training operations for the Chicago Cubs, who had previously played at nearby Hohokam Stadium. The stadium design was led by Populous. The dimensions of the playing surface closely match those of the Cubs' regular home stadium, Wrigley Field. There are many secondary fields at the park, most of which are training and practice fields.
