Blockx crushes the US Open and guarantees a new Grand Slam quarterfinalist
Alexander Blockx has pulled off one of the biggest surprises so far in the US Open 2026, managing to defeat the fifth seed, Flavio Cobolli, and overturning all predictions that may have existed in this section of the draw, where the major circuit representatives have been eliminated.
At just 21 years old, the Belgian has been showcasing his potential throughout the season with sporadic brilliant performances, but few could have foreseen him reaching the round of 16 in the last Grand Slam of the season, especially at the expense of a Cobolli who arrived full of confidence. The final score was 6-7 (4) 6-3 6-0 6-3 in favor of a Blockx who was physically much stronger than his opponent.

This result is very important for the tournament as it guarantees the presence in the quarterfinals of the US Open 2026 of a player who has never reached that stage in a Grand Slam before. Blockx will face Fran CerĂșndolo, with one of them becoming a quarterfinalist who would then face Mensik, Tien, Khachanov, or Bonzi.
It is worth noting that the men's draw of the US Open 2026 is going crazy, especially in this upper part, where there has been a massive fall of high seeds, allowing other players to explore their limits and savor the opportunity to deliver a historic performance, like Alexander Blockx.
On the part of Flavio Cobolli, absolute disappointment for a player who arrived with high expectations and has paid dearly for the physical toll taken during a grueling season. The Italian will need to regroup quickly to aim for a spot in the ATP Finals.
