Ultimate Tennis Showdown (UTS) is the world’s newest, most exciting, innovative tennis league, playing an entirely reinvented game format. The year-round league was founded by Patrick Mouratoglou, who previously coached WTA legend Serena Williams and is now the coach of 2-time grand slam champion Simona Halep and young Danish star Holger Rune. In addition, Patrick also mentors several promising players, including Stefanos Tsitsipas, Coco Gauff, and Alexei Popyrin. UTS introduces a modern format consisting of 40-minute intense matches, a lightened code of conduct, and unique novelties. For instance, UTS cards strongly emphasize strategy and add to the suspense. Live coaching and mid-match interviews allow fans to get inside the player’s minds and immerse into their universe. UTS organised its first events proof of concept following the Covid-19 lockdown. World-famous players that have already participated include Daniil Medvedev, Taylor Fritz, Stefanos Tsitsipas, Matteo Berrettini, Alexander Zverev, and many more. In 2023, UTS returns with four events worldwide. The first three events will occur in the US, Europe, and Asia. Finally, a Grand Final will be held in December in the Middle East.
