Major League Baseball coordinated with commercial landscaping firm BrightView and a “creative experience company” called BaAM Productions to reshape the 159-acre former movie set in Dyersville, Iowa. The site is known to be a popular tourist destination drawing up to 100,000 visitors in a given year. 

BrightView’s Murray Cook told the Des Moines Register he felt the result has a similar feel to old Comiskey Park, the legendary southside stadium that the White Sox team at the center of the “Black Sox” controversy covered by the film. "Obviously this one's in a cornfield," he added. Cook had consulted with MLB on previous pop-up venues at Fort Bragg and Williamsport, Pennsylvania, the home of the Little League World Series. 

The new Field of Dreams complex was completed in time for the announced Yankees-White Sox 2020 game date, which was pushed back a year because of COVID-19. Local NBC affiliate KWWL has a pregame walkthrough of the field here.
