The Atlanta Braves and Cincinnati Reds are playing the first MLB regular season game ever in the state of Tennessee after a rain delay before the first pitch. They are wrapping up a three-game series Saturday night at the MLB Speedway Classic on the diamond constructed on the infield at Bristol Motor Speedway. This racetrack is called “The Last Great Colosseum.” Organizers threw a big party mixing NASCAR themes with baseball with star Tim McGraw performing. Players for both teams stood in the back of pickup trucks and rode around the half-mile bullring racetrack. But a tarp came out as rain picked up before the first pitch was thrown.
