The Ultimate Tennis Showdown (UTS) is an international individual tennis league first played in 2020. The competition was organized by tennis coach Patrick Mouratoglou, and Alex Popyrin — entrepreneur and father of Alexei Popyrin, in response to the disruption of the tennis season due to the COVID-19 pandemic.
The events use a modified scoring format, with matches divided into timed quarters, and players allowed to play power up "cards" during matches to impact the game.
