Carlos Alcaraz followed the example set almost two decades ago by Rafael Nadal, with the Spanish teenager clocking up his 30th season win for a place in the final four of the NextGen Finals on Thursday.
The 18-year-old became the youngest man since Nadal in 2004 to win 30 times in a season.
Alcaraz did it with a 4-0, 4-1, 2-4, 4-3(3) defeat of Argentine Juan Manuel Cerundolo, reaching the semis of the Under-21 competition with a flawless 3-0 group record.
Victory took 84 minutes, with Alcaraz saving nine of 10 break points in the 84-minute success.
“I’m very happy to get to the semi-finals,” Nadal’s heir-apparent said.
“To be able to play in the semi-finals here is amazing. To play these kinds of matches and at this level,
“I’m playing really, really well and feel very comfortable in Milan. I want to end the year with a title.”
Alcaraz has been on fire this week under the eye of former ATP No. 1 coach Juan Carlos Ferrero, losing just one set so far.
