Blockx vs Cobolli Prediction 5 September 2026
🔊 Alexander Blockx and Flavio Cobolli arrive at the US Open for a match where the rankings and current form tell rather different stories. The Italian is in the top 10, but the Belgian has closed the gap considerably over recent months and is a genuine threat to the favourite. Cobolli will need to justify his higher ranking in a contest that looks close to even on hard courts.
Head-to-Head
📊 The two players have one win apiece in their two previous meetings. In April, Blockx won on clay in Monte Carlo - 6-3, 6-3. In August, Cobolli took revenge on hard court in Cincinnati - 7-5, 4-6, 7-5.
Alexander Blockx Player Overview
Blockx opened his US Open campaign with a win over Tomas Barrios Vera - 6-3, 6-4, 6-2, then beat Marco Trungelliti - 6-3, 6-2, 3-6, 6-1. Across those two rounds he won 6 of 7 sets and conceded more than 4 games in a set just once. Both opponents were ranked outside the top 100, so the demands on his serve and return should increase considerably in the third round.
On hard courts this season Blockx has gone 18-27. He has held serve in 85% of service games, hit aces on 10% of service points, and won 77% of first-serve points. On return, he has broken in 21% of return games. The overall numbers look solid, but a significant share of those wins came at lower-level events. His results against top-50 players are noticeably more modest, and his only recent hard-court meeting with Cobolli ended in defeat.
Match Results: Alexander Blockx
Flavio Cobolli Player Overview
Cobolli has spent more time on court. In the first round he was two sets down against Francisco Comesaña before winning 3-6, 2-6, 6-3, 6-4, 6-4. He then dropped the opening set to Tristan Schoolkate and again turned the match around, winning 3-6, 6-3, 6-4, 7-5. Two comebacks from losing positions speak to his ability to maintain his level over a long match, though another slow start would make things considerably harder for him.
In 2026 Cobolli has won 15 of 24 matches on hard courts. He has held serve in 79% of his service games and broken in 19% of return games - Blockx edges him on both figures. That said, Cobolli has faced opponents ranked in the top 50 far more often and has already beaten Paul, Tiafoe and Blockx himself on the surface. That kind of experience against strong opposition matters in a best-of-five format, where one good run of games is rarely enough.
Match Results: Flavio Cobolli
Key factors
- Blockx has won 18 of 27 matches on hard courts this season; Cobolli 15 of 24.
- The Belgian held serve in 85% of service games, against 79% for the Italian.
- Cobolli has played considerably more matches against top-50 opponents.
- Cobolli won their most recent hard-court meeting in August.
- The Italian has won both his matches at this tournament after losing the first set.
Expected scenario
In the opening set, Blockx has the potential to take an early advantage thanks to a more reliable serve. The Belgian won the first set in both of his matches at the tournament, whereas Cobolli has so far struggled to apply consistent pressure on return in the early stages. If the Italian is again slow to find his range, one break may be enough for Blockx.
As the match progresses, the advantage may gradually shift towards Cobolli. The Italian has faced stronger opponents more regularly and has come back after dropping a set on several occasions. A first-set win for Blockx would not therefore guarantee his superiority over the full match: the selected direction concerns specifically the period in which the contrast between the Belgian's fast start and Cobolli's slower start is most pronounced.
Match Result Prediction
Over the full match, Cobolli holds a slight edge. He has faced top-50 opponents more regularly, won their recent hard-court meeting, and has shown he can raise his level after a slow start. On the match result, the more interesting side is with him.
⭐ Editor’s Prediction
Cobolli remains marginally the stronger player over the full match, but has recently been slow to find his rhythm, dropping the first set in 8 of his last 10 matches on hard courts, including both of his matches at this year's US Open.
Blockx, by contrast, has won the first set in both of his New York matches and has a reliable enough serve to protect a small early lead. The combination of Blockx's fast starts and Cobolli's recurring first-set struggles makes the opening set a more justified pick than the match result.
Pick: Alexander Blockx to win the first set.
