MLB has been diligent in recent years to try and expand baseball's fan base and reach audiences that normally don't follow along. Some of that has been on the international side as the league has played games in Tokyo, Seoul, Mexico City, and Monterrey. However, MLB is also looking to expand the game's appeal within the US and the 2025 Speedway Classic featuring the Atlanta Braves taking on the Reds might be the most successful example by the numbers.
For those that are somehow unaware, the Speedway Classic is a game that will happen on August 2 on a field that the league has built inside of Bristol Motor Speedway.
