Memphis' chief rivals have been those based in Nashville. Located approximately to the northeast and connected to Memphis by Interstate 40, Nashville has fielded several teams which have competed in the same leagues as Memphis' teams since the late 19th century. The Redbirds entered the rivalry when they joined the Pacific Coast League in 1998. The teams have been division rivals ever since. Memphis will join Nashville as members of the Triple-A East in 2021. In 2009, Memphis clinched the American Conference North Division title, finishing the season just two games ahead of Nashville which spent the majority of the season in first place. Similarly, Memphis finished the 2014 season two-and-a-half games ahead of Nashville despite trailing the Sounds for most of the season.
