Nashville SC joined Major League Soccer on Feb. 29, 2020 in front of the largest attendance ever recorded for a soccer match in the state of Tennessee. In its inaugural MLS season, Nashville SC defied expectations by becoming the second MLS expansion side to win and advance to the Conference Semifinals in the 2020 Audi MLS Cup Playoffs. Nashville SC returned to the Audi MLS Cup Playoffs in its sophomore season after becoming just the seventh team in MLS history to go unbeaten at home in a season. The Boys in Gold again qualified for the Audi MLS Cup Playoffs in both 2022 and 2023, becoming just the third team in league history to reach the postseason during the team's first four years in existence. Nashville SC inaugurated GEODIS Park, the largest soccer-specific stadium in the United States and Canada, in front of a sellout crowd of 30,109 on May 1, 2022.
