Alexander Blockx vs Flavio Cobolli Prediction

Flavio Cobolli walked off court against Francisco Comesana after turning a two-set deficit into a 3-6, 2-6, 6-3, 6-4, 6-4 victory. It was not a clean opening round, but it showed why the Italian is difficult to eliminate across five sets. He followed that escape by recovering from another slow start to beat Tristan Schoolkate 3-6, 6-3, 6-4, 7-5.

The Alexander Blockx vs Flavio Cobolli prediction must account for Cobolli’s recoveries, Blockx’s more efficient route and a rivalry tied at 1-1. They meet in the US Open third round on an outdoor hard court, with the winner advancing to the last 16. Play is scheduled for Saturday at four o’clock UTC.

Blockx Has Dropped Just One Set in New York

Blockx has made the cleaner progress through two rounds. He opened with a 6-3, 6-4, 6-2 win over Tomas Barrios Vera, avoiding the extra physical and mental burden of a fourth set. He then defeated Marco Trungelliti 6-3, 6-2, 3-6, 6-1.

That second-round score matters. Blockx lost control in the third set but did not allow the match to become complicated. His 6-1 response shut down any prospect of a fifth set and left him with only seven completed sets across his first two matches.

Cobolli has already played nine. The Italian needed five sets against Comesana and four against Schoolkate, losing the opening set both times. If that pattern continues, Blockx has shown enough early-round authority to make the favorite pay for another delayed start.

The Belgian’s wider 2026 rise also supports his price. He has climbed from No. 105 in February to No. 34 and earned the 28th seed in New York. That movement was not built solely on minor events. Blockx reached his first ATP Masters 1000 semifinal in Madrid in May, demonstrating that he can sustain a run against stronger fields.

He has also beaten Cobolli this year. Their Monte Carlo meeting ended 6-3, 6-3 to Blockx. Clay conditions do not provide a direct guide to this outdoor hard-court contest, but the result removes any suggestion that the underdog will be overawed by the No. 6 player.

There is also a clear numerical case for a long match. Their more relevant hard-court meeting in Cincinnati lasted three tight sets, while both men have dropped sets in New York. The lean is over 32.5 games at 1.26, although the short price offers limited room for error if either player wins efficiently.

Blockx’s route to victory begins with the first set. Cobolli has lost the opener in both of his US Open matches, whereas Blockx has won his first set 6-3 in each round. A third repeat would force Cobolli to chase the score against a player who has already proved capable of beating him.

Cobolli Owns the Recent Hard-Court Reference Point

The strongest argument for Cobolli is their Cincinnati match on August 17. He won 7-5, 4-6, 7-5 on hard court in the third round of the Masters 1000 event. The margins were narrow, but Cobolli took both sets that reached 5-5 and handled the decisive phase better.

That result also came during a run to the Cincinnati semifinals. Cobolli eventually lost there in straight sets to Arthur Fils, but his performance across the tournament reinforced his hard-court credentials. He had already won an ATP hard-court title in Acapulco earlier in 2026.

Cobolli’s season has included success away from hard courts too. He reached the French Open final before finishing runner-up to Alexander Zverev. Combined with a rise from No. 20 in February to No. 6, that run explains why he is the fifth seed and why the market gives him a narrow edge here.

His first two rounds have shown vulnerability, but also problem-solving. Against Comesana, he lost the opening two sets before winning three consecutive sets. Cobolli later said he felt pressure but loved playing where pressure was high. The comeback supplied a concrete example rather than an empty declaration.

Schoolkate created another immediate problem by taking the first set 6-3. Cobolli again changed the direction of the match, winning the next three sets and closing it 7-5 in the fourth. Two recoveries in succession may indicate that his level has fluctuated, yet they also show that one poor set does not settle a best-of-five contest against him.

That format should help the higher-ranked player. Blockx’s Monte Carlo victory was completed in two sets, and their Cincinnati contest used the best-of-three format. In New York, Cobolli has more time to recover if Blockx starts quickly, as he did against Barrios Vera and Trungelliti.

The Italian does not need to dominate every phase. He needs to stay close enough to apply pressure late in sets. Cincinnati offered the clearest template: two 7-5 sets won by Cobolli, with Blockx taking the middle set. Another match decided by a handful of points would favor the player who captured those late-set exchanges less than three weeks ago.

The 1.85 Favorite Price Leaves Almost No Cushion

Cobolli is offered at 1.85, with Blockx at 2.07. Those numbers describe a near pick’em rather than a substantial gap between No. 6 and No. 34. For more tournament selections and market assessments, Tennis Predictions tracks the prices alongside each matchup.

The ranking difference points toward Cobolli, as do his Acapulco title, French Open final and Cincinnati victory over Blockx. The concern is that buyers of the favorite must accept two consecutive lost opening sets and nine sets of work through two rounds. Blockx has been more economical and has won five of his seven sets by margins of at least three games.

At 2.07, the Belgian is not priced as a remote outsider. That is appropriate. He owns a straight-sets victory over Cobolli from Monte Carlo, has surged 71 ranking places since February and has opened both US Open matches with 6-3 sets. His case is strong enough to keep the favorite’s price above odds-on territory.

Cobolli’s 1.85 still receives the narrow preference because the latest hard-court meeting carries more relevance than their clay result. He also owns the deeper collection of major 2026 achievements and has survived two difficult New York tests without allowing an early deficit to become elimination.

Our pick is Flavio Cobolli to win at odds of 1.85.

Conviction is exceptionally low, sitting close to the bottom of the AI’s confidence range. The tight prices are justified by Blockx’s efficient opening rounds and the 1-1 head-to-head record. Cobolli has the stronger overall résumé and the recent hard-court win, but his repeated slow starts make 1.85 a marginal position rather than a forceful one.
