The Kansas City Royals and Hallmark Cards announced a partnership to develop a new downtown ballpark as part of a $3 billion stadium project in Kansas City.

The proposal calls for constructing a new baseball stadium in the downtown area, which would be integrated with mixed-use development surrounding the facility. The partnership brings together the Major League Baseball franchise with the greeting card company headquartered in Kansas City.

The project represents a significant investment in Kansas City's downtown area and would relocate the Royals from their current home at Kauffman Stadium, where they have played since 1973. The current stadium is located in the Truman Sports Complex in eastern Kansas City.

Details about the timeline for construction, specific location within downtown Kansas City, and financing arrangements for the $3 billion project were not immediately available. The mixed-use development component suggests the ballpark would be part of a larger urban development initiative.

The announcement marks the latest in a series of Major League Baseball teams exploring new stadium projects or relocations to downtown areas in recent years.
