For the second year, the ATP NextGen Finals are taking place to show off the young talent on tour, particularly male players 21-and-under who show the most promise. This year, some rules have changed in Milan, and who better to remind fans of those changes than the competitors themselves?

Some of the rules are from last year, but those were already dramatically change the game compared to the rest of the tour. The biggest innovations include shorter, 4-game sets, no line judges with all shots tracked by Hawk-Eye Live and on-court coaching via headsets. On top of that, there has been no lets or ad-scoring. New this year is ball boys not delivering towels anymore and an even shorter warm-up. 

Almost the entire field in Milan this year is new, except Andrey Rublev who reached the final last year. There are some familiar faces, such as Frances Tiafoe and Taylor Fritz, with relative unknown names mixed in including Hurbert Hurkacz, Jaume Munar and Italian wild card Liam Caruana. 

Play began on Tuesday with Alex de Minaur, Andrey Rublev, Stefanos Tsitsipas and Frances Tiafoe scoring wins.
