Which MLB Park Is the Smallest?
The Athletics have the smallest ballpark in the majors with a capacity of 13,416. Sutter Health Park is the temporary home of the Athletics after they departed Oakland at the end of the 2024 season. If everything goes to plan, the Athletics will relocate to Las Vegas for opening day of the 2028 season.
It is the permanent home of the Sacramento River Cats, the Triple-A affiliate of the San Francisco Giants. To prepare the stadium for the Athletics’ arrival, the ballpark underwent major renovations, including the installation of improved technology to maintain the grass surface and the construction of a new clubhouse.
With the Tampa Bay Rays returning to Tropicana Field for the 2026 season, Sutter Health Park is by far the smallest MLB stadium.
Tropicana Field is the only other ballpark with a capacity of under 34,000.
