Blockx vs Barrios Vera Prediction 31 August 2026
🔊 Alexander Blockx and Marcelo Tomas Barrios Vera both arrive at the US Open having reached significant career milestones. The 21-year-old Belgian is making his first appearance at the tournament as a seeded player, while the 28-year-old Chilean finally made it through qualifying at the fifth attempt to reach the main draw for the first time. For Barrios Vera, it is the reward for years of perseverance at this event - though his first-round opponent is one of the fastest-improving players of the season.
Head-to-Head
📊 Alexander Blockx and Marcelo Tomas Barrios Vera have never previously met.
Alexander Blockx Player Overview
Blockx is currently ranked 32nd in the ATP rankings, a career-high. On hard courts in 2026, the Belgian has won 16 of 25 matches, held serve in 85% of his service games and hit aces on 10% of his deliveries. He has broken in 21% of his opponents' service games, so his game is built primarily around a reliable serve.
In Cincinnati, Blockx beat Mariano Navone 6-3, 6-4, then pushed Flavio Cobolli to three sets, losing 5-7, 6-4, 5-7. Earlier in Montreal, he fell to Jiří Lehečka 3-6, 4-6. Those results suggest he can compete with players from the upper end of the rankings, though he is not always consistent in the closing stages of tight sets.

Marcelo Tomas Barrios Vera Player Overview
Barrios Vera is ranked 144th in the ATP rankings. On hard courts this season he has won 9 of 16 matches, held serve 78% of the time and broken in 21% of his opponents' service games. The Chilean plays more of his tennis on clay, and his return game does not always create enough opportunities against big servers.
Barrios Vera came through US Open qualifying with wins over Juan Carlos Prado Angelo (6-2, 5-7, 6-0), Genaro Alberto Olivieri (6-3, 6-1) and Daniel Rincon (6-4, 6-3). He dropped just one set across those three matches, though all three opponents are ranked outside the top 150. He will face considerably more firepower on serve in the main draw.

Key factors
- Blocks is playing his first US Open as a seeded player.
- The Belgian held serve at 85% on hard courts in 2026.
- Barrios Vera has reached the US Open main draw for the first time.
- The Chilean won his last five sets in qualifying.
- All of Barrios Vera's qualifying opponents were ranked outside the top 150.
Expected scenario
Blockx will look to gain an early edge with his first serve and attack the next ball. Barrios Vera is unlikely to create break points consistently, so any weak service game from the Chilean could prove decisive in a set.
The qualifier has the ability to stay level early on and draw on recent match practice on these courts. Blockx, though, is a clear step up in terms of serve quality and pace of play from Barrios Vera's recent opponents. If the Belgian avoids a prolonged dip in level, this match should not go to a fifth set.
Match Result
A Blockx win looks the most likely outcome, but the odds on the favourite are too short. A large handicap requires not just overall dominance but several early breaks, and Barrios Vera held serve comfortably in qualifying. Backing a short match better accounts for both the Belgian's quality and the Chilean's ability to make at least one set competitive.
⭐ Editor's Prediction
Blockx has held 85% of his service games on hard courts and has competed comfortably against significantly stronger opposition than the players Barrios Vera beat in qualifying. The Chilean is unlikely to create consistent pressure on return, and dropping serve could hand the Belgian control of a set quickly.
The main case here is for Blockx to win without a drawn-out battle of sets. Even one competitive set leaves room for the total to come in under, if the others go comfortably his way. A prolonged dip in form from the Belgian remains a risk, but the current gap in serving and level of opposition makes the shorter scenario the more attractive one.
Our pick: Total Games - Under 35.5
