Ultimate Tennis Showdown

The Ultimate Tennis Showdown (UTS) is an international individual tennis league that was founded in 2020. The competition was organized by tennis coach Patrick Mouratoglou and businessman Alex Popyrin, father of professional tennis player Alexei Popyrin, in response to the disruption of the tennis season due to the COVID-19 pandemic.

The first three events were held in 2020; the first two were organized at the Mouratoglou Tennis Academy in Biot near Nice and the third was held in Antwerp. In 2021, UTS returned to the Mouratoglou Academy for its fourth edition. After a two-year absence, UTS returned in July 2023 with a series of three events in the United States, Germany, and South Korea, designed to culminate in a new "Grand Final" at the end of the season.

All events use a modified scoring format, with matches divided into timed quarters. Among the features UTS has built into the tournament to differentiate the game are "power-up cards" that can affect the amount of points a player can accrue within a quarter.

Format
UTS matches use a different format in comparison to traditional rules, including matches being divided into timed quarters rather than sets, a 15-second shot clock for serves and the ability to take a coaching timeout once per-set, and "cards" — which allow players to affect the game (such as taking away the opponent's second serve). Until UTS 4, even if a player had a majority in quarters, all 4 quarters were played for averaging purposes. If two players are equal in the amount of quarters won, a 'sudden death' is played, where the first player to win two consecutive points wins the match. Introduced in UTS 4, players only have one serve per point, where lets are played; and 'KO Mode', where if a player is leading by 10 points in the quarter, it is declared over.

The UTS also does not enforce a code of conduct.
