A ballpark can have a significant impact on MLB betting decisions.

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.

As it stands, the Athletics are planning to leave Sacramento for Las Vegas at the end of the 2027 season. Sutter Health Park is the permanent home of the Sacramento River Cats, the Triple-A affiliate of the San Francisco Giants.

Ahead of the arrival of big-league baseball, the ballpark underwent major renovations, including the installation of improved technology to maintain the grass surface and the construction of a new clubhouse.

Tropicana Field, home of the Tampa Bay Rays, is the only other ballpark with a capacity of under 34,000.
