Vacherot vs Blockx Prediction 30 September 2026
🔊 Valentin Vacherot and Alexander Blockx are appearing at a 500-level event in Tokyo for the first time, following Blockx's sensational run to the US Open quarter-finals. The upcoming tournament will be a debut for the 21-year-old Belgian, and equally so for his more experienced and higher-ranked opponent Valentin Vacherot. The match will also be their first meeting at professional level. That makes the outcome all the more interesting, particularly given that Blockx is the slight favourite in the odds.
Head-to-Head
📊 Valentin Vacherot and Alexander Blockx have no previous meetings on record.

Valentin Vacherot Player Overview
Valentin Vacherot arrives in Tokyo after an inconsistent run - just four wins from his last ten matches. Most recently, at the ATP 250 in Chengdu, he lost in the first round to Lloyd Harris, a player ranked outside the top 100, despite having previously won two matches against opponents of a comparable level to the South African during Finland's Davis Cup tie. Vacherot holds 83% of his service games, which keeps him competitive even when he struggles to maintain rhythm during rallies. However, his set-winning percentage (44%) is lower than his upcoming opponent's, and he has been bagelled in four of six possible sets, pointing to difficulties sustaining concentration over the full course of matches.

Alexander Blockx Player Overview
Alexander Blockx has shown more consistent form - the same four wins in recent matches, but with a more stable pattern of results, having recently made a surprise run to the US Open quarter-finals, knocking out, among others, top-10 player Flavio Cobolli. The Belgian holds 77% of his service games and has a slightly better set-winning percentage than his upcoming opponent (46 against 44), which matters for controlling the full distance of the match. Blockx hits winners less frequently than Vacherot, but he compensates through rally play and effective returning, converting nearly 40% of break points.

Key factors
- Valentin Vacherot lost the second set in 5 of his last 6 matches.
- Alexander Blockx recently reached the US Open quarter-finals, while Vacherot went out in the third round of that Major.
- Alexander Blockx's set-winning percentage is slightly higher than Vacherot's.
- The two players have comparable serving stats, but the Belgian is stronger on return.
Expected scenario
The match may favour Alexander Blockx on the back of better recent results and a more consistent record in converting sets. That said, the contest could be close in certain phases, largely due to Valentin Vacherot's more effective serve. However, once rallies develop, the Belgian is likely to wear his opponent down, and early in games he may also put the Monégasque under pressure with aggressive returning.
⭐ Editor's Pick
Valentin Vacherot's poor results during the North American hard-court swing, along with a difficult start to the autumn hard-court series, lead us to side with the current odds favouring the lower-ranked Alexander Blockx. Despite having had no match practice since the US Open, his results at that Major alone tip the balance in the Belgian's favour. The main scenario for this match is that Alexander will be the closer to victory, thanks to greater consistency throughout, against an opponent who may largely rely on a powerful serve. Our prediction: Blockx to win.
