Flavio Cobolli saw his US Open 2026 campaign come to an end in the third round at Flushing Meadows, falling in four sets to Belgium’s Alexander Blockx. According to match reports from the venue, Blockx rallied past the Italian contender with a scoreline of 6-7(4), 6-3, 6-0, 6-3 after two hours and 45 minutes of play at the Louis Armstrong Stadium in New York.
How Alexander Blockx Turned the Match Around Against Flavio Cobolli
The encounter at the New York Grand Slam began strongly for Cobolli. The Roman athlete claimed a tight opening set in a tiebreak, taking it 7-6 after an intense battle. However, momentum shifted swiftly toward the Belgian side of the court.

According to tournament statistics and match reporting, Blockx seized control in the second set with a 6-3 scoreline before dominating the third set 6-0. The world number 34 maintained his aggressive baseline rhythm into the fourth frame, securing another 6-3 win to close out the match and secure his spot in the tournament’s second week.
A Measure of Revenge in New York
For Blockx, the victory served as direct redemption. Match accounts note that the Belgian player reversed the outcome of his previous narrow defeat to Cobolli earlier in the season at the Cincinnati Masters 1000.

With this hard-fought four-set win completed on September 5, 2026, Blockx advances to the fourth round of the tournament. Official tournament scheduling indicates that the Belgian competitor will next face Argentina’s Francisco Cerúndolo, who booked his own spot in the round of 16 following a dramatic five-set comeback victory against ninth seed Taylor Fritz.
Struggles and Fatigue for the Italian Contender
The elimination halts Cobolli’s run at the final major of the tennis season, preventing him from reaching the second week in New York. While the defeat stings for the Italian contingent following a demanding week of fixtures at Flushing Meadows, Blockx moves forward to test his form against Cerúndolo.
