Sloan Park, home of the Chicago Cubs during Spring Training, recently completed a construction project to enhance its player development environment with new training, technology and support spaces designed to elevate performance and operational efficiency. Located in Mesa, the main clubhouse building at Sloan Park received a 6,400-square-foot addition, with a female staff locker room, umpire locker room, and a multiuse open office and meeting area to support the growing needs of the organization. Another 18,000-square-foot building that houses pitching and hitting tunnels, a video analysis room, and a suite of support spaces designed to integrate advanced training technologies is scheduled to open before pitchers and catchers report to 2026 Spring Training camp on Feb. 11.

“As a firm deeply rooted in Arizona, we take great pride in contributing to a project that strengthens one of the region’s most iconic sports destinations,” said Mark Phillips, AIA, Associate and Team Leader at CCBG Architects, which served as the local architect of record for the project. “This expansion enhances the Cubs’ ability to train, develop, and support athletes at the highest level, and it reflects the collaborative spirit shared by the entire project team.”

Sloan Park opened in 2014 as a state of the art complex replacing Hohokam Stadium and quickly became the largest spring training venue in Major League Baseball, with a capacity of 15,000. Designed to echo the character of Wrigley Field, the facility attracts record crowds each spring and serves as a year round community asset. The project is owned by the City of Mesa and the Chicago Cubs baseball organization.

The lead architect is Populous, with Mortenson serving as general contractor. The full squad is expected to report for its first workout on Feb. 16, with the team’s first Cactus League game vs. the White Sox on Feb. 20 at Sloan Park.
