Carlos Alcaraz has achieved remarkable success in his tennis career so far, completing the career Grand Slam at the age of 22.
Alcaraz became the youngest man to complete the career Grand Slam, doing so by winning the Australian Open earlier this month.
Following his success in Melbourne, Alcaraz took a brief break from tennis, as well as deciding to withdraw from the Rotterdam Open.
That ATP 500 tournament is now underway in the Netherlands, and is followed by another in Qatar, which Alcaraz is set to play in.
What would the score be if Carlos Alcaraz faced prime Roger Federer?
Who is winning and in how many sets?
John Isner recalls hugely enjoyable practice with 17-year-old Carlos Alcaraz
Alcaraz won the Rotterdam Open in 2025, representing one of the 25 career ATP titles secured by the Spanish superstar.
Following the latest title, former player John Isner has been reminiscing about the world number one, sharing insight into a practice session they once took part in long ago.
“I practiced with Carlos in Acapulco in 2021, so he was 17,” Isner revealed on the Nothing Major Show.
“He was ranked 160 and was a wildcard. We had a 5pm practice on Centre Court, it’s the Sunday before the tournament and it’s brutally hot.
“I was hitting with a 17-year-old kid and I’m not making this up, he was so excited to hit with me. He was like this is awesome.
“He was so good! I did tell my coach after that practice that he was going to be number one in the world because the ball just comes off his racket differently, even at 17 years old.
“He would not take mini water breaks. The guy put me in a body bag. It was so hot and he just kept ripping and ripping and ripping.
“I said time-out Carlos! I had to go to the sideline and get a sip of water out there. He was like ‘all good’. He was so nice!”
What has Carlos Alcaraz achieved on the ATP Tour?
Even with Alcaraz’s talent, it was quite the call from Isner, with the former of course going on to become world number one.
But Alcaraz’s achievements have not been limited to that ranking and a career Grand Slam, which is a scary thought considering he’s only 22 years old.
He is already halfway to 50 ATP titles, while his other career achievements include 287 wins compared to 65 losses, and over $60million in prize money.
Will Carlos Alcaraz win the Calendar Slam in 2026?
If not, which Grand Slam is he going to fail to win?
His 2026 season alone epitomises just how lethal the superstar is, with Alcaraz boasting seven wins, one title and $2,771,785 in prize money from the only tournament that he’s played.
That’s a real warning to the rest of the ATP Tour, who may be worried about just how much success the Spaniard will go on to achieve as the years progress.
In Grand Slams alone, he’s now won titles on grass, clay and hard courts, and has a 7-1 record from his major finals.
Those efforts, combined with his charismatic playing style and infectious smile, have helped him gain a huge following inside and outside of tennis.
