There hasn’t been a full-fledged changing of the guard just yet in men’s tennis, but there has been a gathering of the arms.

While Roger Federer, Rafael Nadal, Andy Murray and Novak Djokovic have held a near monopoly on Grand Slam titles since 2005, a number of rising talents have shown enormous potential over the last few seasons.

With the emergence of these young players, the ATP World Tour now features more depth than it ever has. Even in the nether regions of the top-100 rankings, there exist young players who can shock the world’s best on any day.

Grigor Dimitrov and Milos Raonic have long been hailed as the next big tennis stars, and their results so far have backed up the hype. But to make good on that promise, they’ll have to finally break through and win a major.

Teenagers like Nick Kyrgios and Borna Coric aren’t as far along in their development as Dimitrov or Raonic are, yet in their short professional careers, they’ve both shown the ability to produce monumental upsets.

Big hitters like Bernard Tomic and Jack Sock have also flashed serious game over the years. Joining them on the list of top young talents is the sinewy David Goffin, who grinds away at less-glitzy tournaments and racks up wins and confidence.

The following slides will examine what makes these players the best talents under 25 while also highlighting other prospects on the rise. Be prepared to hear these names often over the next few years.

10. Pablo Carreno Busta

Age: 24

Spain has been a breeding ground for top-quality players over the last decade, and the next one may be Pablo Carreno Busta.

Carreno Busta made his biggest leap in 2013, skyrocketing from No. 654 to No. 66 in the rankings and winning that year’s Most Improved Player of the Year award based off his success at the Futures and Challenger levels.

In 2014, Carreno Busta spent his first full year on the ATP World Tour with notable results, including a third-round finish at the U.S. Open. He also defeated top-20 players Kevin Anderson and Gael Monfils in Monte Carlo before falling to Djokovic in the third round.

The red clay is like a second home for Carreno Busta. It’s his most comfortable surface, and the dirt rewards his game. What he lacks in power and flash he overcomes with grit and patience.

Carreno Busta may not have overwhelming talent like his peers do, but his consistent baseline game and clay-court prowess make him a player who should hover around the top 30 in the future.
