Alexander Blockx
Alexander Blockx is a Belgian professional tennis player who broke through to the top of the game with a run to the Madrid Open 2026 semi-finals as a qualifier — winning five matches in a row, including a quarter-final victory over defending champion Casper Ruud and a first career win over a top-10 opponent. Born in Antwerp on 8 April 2005, Blockx had spent years on the Challenger circuit and reached the Next Gen ATP Finals before that Madrid breakthrough lifted him to a career-high ranking and into the top 40 for the first time.

Playing Style & Strengths
At 6 ft 4 in, Blockx is a physically imposing player whose game is built around his size and athletic foundation. He is a right-hander who uses his serve as a platform to build points, with heavy groundstrokes from both wings. What became evident during his Madrid run was his ability to maintain a high level across multiple rounds, beating a different quality of opponent each time and adjusting his approach accordingly — a tactical intelligence beyond what his tour experience would suggest.
His clay game is newer than his hard-court game, but his physical attributes translate naturally to the slower surface, and Madrid demonstrated that the clay game was there once his confidence on the surface arrived. He had said before that run that he never had much confidence on clay; his results since have changed that assessment.
Blockx Betting Tips & Predictions
Blockx is a credible value pick in outright markets at tour level, particularly now that Madrid confirmed he can beat top-10 players across multiple rounds. His physical, baseline-heavy game makes him difficult to dismiss on slower surfaces, and his hard-court experience is his deepest. He is best backed at longer prices in Masters and ATP 500 events rather than as a short-priced favourite. Follow our tennis betting tips for the latest Blockx predictions.
