UTS 4

The fourth edition of UTS took place on May 24 and 25, 2021.

It was played on the clay courts at Mouratoglou's academy rather than the hard courts. A rule change meant that each player would only have one serve per point. This season also introduced 'KO Mode', where if a player is leading by 10 points, the quarter is declared over.

"The Demon" Alex de Minaur was the defending champion, but chose not to participate.

"The Tornado" Corentin Moutet won the event, defeating "The Hotshot" Taylor Fritz 12–14, 15–11, 13–12, 16–8.
