MLB did, in fact, build it. The Yankees and White Sox are all set to play Thursday night in Dyersville, Iowa. The town has a population of fewer than 5 thousand people. The field is built in the middle of a cornfield, just like the iconic 1989 ‘Field of Dreams' movie. The makeshift stadium is set to hold 8,000 fans, which is more than Dyersville’s population. The field is just miles away from the original set of the movie.
