Stefanos Tsitsipas, 9. It was a triumphant season for the 20-year-old. Four ATP finals, two wins (Next Gen Finals and Stockholm) and two losses (Barcelona and Rogers Cup, against Rafael Nadal). Best ranking (15) and fourth round at Wimbledon.
A tennis beautiful to see. Flair and talent are the innate qualities in Tsitsipas; if he were to achieve mental strength and regularity, he could do well in the Slams, too. Top player! Alex De Minaur, 8.
The final of the ATP Next Gen Finals must give him confidence. However, his solidity of his tennis is excellent starting points. At 19, he can improve a lot and the three finals (lost) in 2018 are already a good business card.
On the launch pad! Frances Tiafoe, 7. Good season for the American. First ATP 250 title, in February at the Delray Beach International Tennis Championships, and second final of the year in May, lost at the Millennium Estoril Open.
He has the qualities to become the best American player of his generation. Growing! Jaume Munar, 6. He still has to show his best tennis. He can still grow, especially in clay tournaments, where, like many other countrymen, he gives the best of himself.
Will he be famous? Hubert Hurkacz, 6. The Pole can definitely use his serve as a winning weapon. This season he has achieved the best results in the Grand Slam tournaments. However, he still needs to make improvements from the physical and technical point of view.
However, a positive season! Taylor Fritz, 6. Reaching the third round at the US Open 2018 is his best career result in a Major, so far. This result balances a shaky season, in which the expectations on him were many.
Passing grade! Andrey Rublev, 5. He was the real big disappointment of the year, among the Next Gen youth. After his spectacular 2017, everyone expected the leap of quality. The Russian, on the other hand, partially disappointed expectations, despite the fact that the start of his season in Australia was brilliant.
