Major League Baseball has played at the “Field of Dreams” movie site. Now baseball is eager to see just how big a crowd will show up for a game at a NASCAR bullring of a track. And Bristol Motor Speedway can hold a lot of people. It’s part of Commissioner Rob Manfred’s push to take MLB to new places. MLB played a game at the movie site in Iowa in both 2021 and 2022. The MLB Speedway Classic will be played Aug. 2 between Cincinnati and Atlanta in a track that holds more than 146,000 for racing. Bristol set a college football record with 156,990 fans in 2016.
