Alexander Blockx: In Focus

Alexander Blockx has qualified for the Next Gen ATP Finals presented by PIF for the first time. The 20-year-old will be the first Belgian player to compete at the 20-and-under event.

Born to Ukrainian parents who were both professional athletes, Blockx’s father, Oleg, was a track athlete specialising in hurdle races, while his mother, Natalia, was a swimmer. Despite this diverse sporting background, Blockx has never played any sport besides tennis.

Blockx is under the guidance of Philippe Cassiers, who has coached the rising star since the 6’4” Antwerp native was aged four. A highlight of their partnership came in 2023, when Blockx became the junior No. 1 in singles and doubles.

In 2025, Blockx won two ATP Challenger Tour titles and the 20-year-old recorded his first win at an ATP Masters 1000 event in Cincinnati, where he defeated Marcos Giron.
