Redbirds–Sounds rivalry

The Redbirds–Sounds rivalry is a Minor League Baseball rivalry between Tennessee's two Triple-A baseball teams, the Memphis Redbirds and the Nashville Sounds. The teams compete in the West Division of the International League. Their games are played at Memphis' AutoZone Park and Nashville's First Horizon Park. From 2012 to 2015, the rivalry was incorporated into a promotion called the I-40 Cup Series.

Separated by an approximately 200-mile (320 km) stretch of Interstate 40, competition between professional baseball teams from Memphis and Nashville began in 1885 in the original Southern League. The cities later fielded teams in the Southern Association and modern Southern League. The rivalry between the Redbirds and Sounds began in 1998 when both teams became members of the Pacific Coast League and continued in 2021 following placement in the Triple-A East, which became the International League in 2022.

Through the completion of the 2024 rivalry series, the Sounds lead the 27-year series versus the Redbirds with a win–loss record of 231–197 (.540). Since the first Redbirds–Sounds game played on May 17, 1998, the Sounds have led the all-time series for all but one day. A Memphis win on August 24, 2000, tied the record at an even 22 games apiece. Nashville won the next day's game and has not again relinquished the lead.
