The future looks very bright on the ATP Tour. Young players have been making waves all season, notching victories over top players, achieving rankings milestones and generating new fans and excitement. But which young players are destined for stardom? While there's no guarantee, we've ranked the top 10 ATP young guns, aged 20 and younger for you here. Have a read and let us know what you think.



1. Borna Coric Of all the players aged 20 and under on the ATP Tour, Coric has the highest ranking—and he won’t be 19 until November 14. He’s already notched wins over Rafael Nadal and Andy Murray in addition to reaching three tour-level semis. And the results match the game. Coric has a mature, physical style that can grind down opponents.

The Croatian is often compared to Novak Djokovic, and when you watch him you can see why. He’s lean, lithe and quick, he’s a fantastic defender, but he can be a big-time shotmaker when he wants to.



Coric will have to add more attack to his game and learn to position himself more offensively on the court in the years to come, but with his attitude, professionalism, stamina and athleticism, he looks like a definite Top 10 talent.

2. Nick Kyrgios The only thing that will keep Nick Kyrgios from becoming a Grand Slam winner is his head. He’s the most talented shotmaker of his generation, with an explosive serve, a monster forehand, and a knack for performing in the clutch. He’s already scored two Grand Slam quarterfinal appearances, notched wins over Roger Federer and Rafael Nadal, and proven that he belongs—and thrives—on the big stage.



But Kyrgios, unlike Coric, is prone to losing the script and letting his emotions and his lust for the spotlight override his decision-making on the court. Oftentimes, he lets his mind wander. Sometimes his thirst for drama seems to spur him on to magical moments, but at other times it clearly hurts his focus. And some of the things he says and does on the court has caused the media in his own country to turn against him--it's not a good dynamic for a rising player to have.



As of now Kyrgios possesses top 10 talent but lacks the mindset to match.



3. Thanasi Kokkinakis The Aussies are in luck. They’ve got two of the brightest stars on the ATP Tour. Kokkinakis, still 19, has already won three five-setters this year, and in two of them he battled back from two sets to love down. That’s impressive all by its lonesome, but Kokkinakis has impressed in many other ways in 2015. He’s gone 13-0 in qualifying matches this year, which has helped him raise his ranking from 150 to his current slot at 72. He also proved resilient when he won the Bordeaux Challenger this spring after missing the Rome cutoff due to a fire at Fiumicino Airport.

Kokkinakis possesses a lanky frame at 6’5”, but moves remarkably well for his size, serves big and hits big, but with a lot of margin. The Aussie has a great game for today’s slower, higher-bouncing surfaces, and a great fighter’s mentality on court. He’s going to be a good one. Maybe great.



4. Andrey Rublev The Russian is explosive, lightning-quick and fiery, and once Andrey Rublev puts a bit more muscle on his sinewy frame, he could be one of the most dangerous—and successful—players on tour. At just 17 Rublev has made big waves on the senior circuit in 2015, going 8-7 at the tour-level and rising from just inside the Top 500 to his current ranking of 190.



In May, Rublev became the first teenager to win matches at five different ATP events since Rafael Nadal in 2004.

Pablo Carreno Busta in three sets.



Rublev could be the future of Russian tennis, but that’s not all—he could be the future of tennis, or at least a big part of it.



5. Alexander Zverev He’s tall lanky and looks to be still growing into his body. But German Alexander Zverev is already proving to be a potential star at the ripe age of 18. Though he hasn’t matched his breakout semifinal performance from Hamburg last summer (yet), he’s held his own as a known quantity at the ATP-level this season, going 8-6 since March.



A very powerful ball striker who is comfortable on any surface, Zverev could be a player in the ilk of



6. Hyeon Chung Hailing from South Korea, the 19-year-old has had a breakout season. Paced by his beautiful, versatile backhand and cool, calm on-court demeanor, Chung become the second man from his nation to break into the ATP’s Top 100 in April. Earlier in the year, Rublev had become the third-youngest to win a match at the Miami Open when he defeated world No. 54in three sets.Rublev could be the future of Russian tennis, but that’s not all—he could be the future of tennis, or at least a big part of it.He’s tall lanky and looks to be still growing into his body.
