‘Does this little guy also want to try a ball?’
That was the question that started it all for Alexander Blockx, who began playing tennis at age four. Blockx’s brother Maxime, three years his senior, was taking tennis lessons and while Alexander was watching courtside, coach Philippe Cassiers uttered the phrase that kickstarted the Belgian’s journey in the sport.
To this day, Blockx is coached by Cassiers, a 15-year partnership that has featured great success. Blockx became the junior No. 1 in singles and doubles in 2023, the same year he won the Australian Open boys’ singles event.
Competing mostly on the ATP Challenger Tour this season, the 19-year-old is living out his dream as a professional tennis player, a pinch-me moment for someone whose start in tennis was nearly accidental.
“It wasn’t planned for me, I was just going with to see [my brother] a bit,” Blockx recalled to ATPTour.com. “Eventually when we got there, the coach asked my parents, ‘Does this little guy also want to try a ball?’ I said, 'Yes', and I started playing and never stopped.”

Cassiers, who runs a tennis academy outside of Antwerp, instantly noticed Blockx’s natural ability.
“There was a little boy sitting on the bench next to mommy and daddy — and that was Alexander,” Cassiers said. “I asked, ‘Do you want to try?’ He stood up and was like, ‘Let’s do it’. We threw him a couple balls and you could tell he was really motivated, ready to play right away. He wasn’t scared. He was ready to go for it and it was really fun. I talked to his parents, ‘Maybe we should try training for the little one as well’. We have been working ever since.”
Blockx is not the first professional athlete in his family. His father Oleg was a track athlete, excelling in hurdle races while Blockx’s mother Natalia was a professional swimmer.
The #NextGenATP teen has never played any sport besides tennis. As a child, he was too busy dominating tennis tournaments, even above his age group.
“You have big dreams, but when I realised I was good at the sport was when I was playing with guys older than me, two or three years older than me. Because against my age and a year older, I barely lost a game every time we played until the age of 14,” said Blockx, who is 24th in the PIF ATP Live Race To Jeddah.
“First, I played the Belgian tournaments. I was winning almost everything and then my coach said, ‘Okay, now we are going to play a higher age group'. I started winning everything so we started playing international to see how that goes. In under 12s, I played 45 matches and won 42 I think. So then we were like, ‘Okay, there’s real potential'. At the age of 12, I realised I want to go all in and it might actually work out.”
Currently No. 264 in the PIF ATP Rankings, Blockx has gained more attention since the start of 2023, when he became Belgium’s third junior Slam champion and first at Melbourne Park. Jacques Brichant (1947) and Kimmer Coppejans (2012) triumphed at Roland Garros.

“It was amazing. Also because of the way I won it, 11/9 third-set tie-breaker [in the final],” Blockx said. “The whole week I played some good players: [Joao] Fonseca, against Learner [Tien] in the final.”
Blockx this year has made three semi-final appearances on the ATP Challenger Tour, with two of those runs coming prior to a two-month injury layoff in the middle of the season. Blockx was playing his second match in what was supposed to be a five-week Asian swing in April when he tore a ligament in his right ankle, sidelining him until mid-July.
Now back at full health, Blockx showed flashes of his best level last week when he made his Davis Cup debut, which he labelled as, “one of the best experiences of my life so far on a tennis court”. Blockx represented his home country against Italy and pushed former World No. 6 Matteo Berrettini to three sets.
One key element in Blockx’s breakthrough, according to Cassiers, has been his charge’s genuine love for the sport.
“He has a passion for tennis that is really unbelievable,” Cassiers said. “It's becoming more of an obsession at the moment. He’s really, really into the game. I see many players during the last years, and I’ve never seen a player this passionate and obsessed with the game and [with] the will to improve.
“Off the court, he’s following websites, Challenger TV, YouTube and all these things. You can ask him very hard questions, ‘In 2020, who played the quarter-finals of Madrid?’ Or whatever, he is going to be able to give you an answer with the scores. Off the court, he’s still busy with tennis things.”
