Last summer, Minor League Baseball sent the biggest baseball that could legally travel the highway on a road trip across the country—all to unite Minor League clubs and their fans around setting a Guinness World Record.

The 8-foot, 1,200-pound spectacle drew crowds as it traveled from ballpark to ballpark, giving fans a chance to add their signature and become part of baseball history—resulting in a 69.2% lift in attendance across all tour stops.

The tour culminated at MLB’s NY headquarters. Commissioner Manfred added the historic final signature and Guinness certified the record at 6,750 signatures.
