Jannik Sinner’s 81-Minute Masterclass Sets Up All-Italian US Open Quarterfinal

Defending champion Jannik Sinner delivered a ruthless performance at Arthur Ashe Stadium, crushing Alexander Bublik 6-1, 6-1, 6-1 in just 81 minutes. The Italian broke serve in every set and benefited from 13 double faults by his opponent. In total, Sinner claimd 86 points to Bublik’s 46 — a margin that reflected the gulf in class (AP News).

The efficiency of his victory not only showcased Sinner’s relentless baseline precision but also sent a clear message to the rest of the field: the defending champion is in ruthless form.

The victory pushed Jannik Sinner’s Grand Slam hard-court winning streak to 25 matches, a run that ties him with the longest in the Open Era and places him alongside greats such as Novak Djokovic and Roger Federer (Reuters).

It also carried a personal edge. Earlier this summer, Bublik upset Sinner in the Halle final on grass. This emphatic turnaround in New York provided swift revenge.

“Sometimes it’s nice to play against players who beat you before,” Sinner said.

“It cleanses the pain a little bit.”

All-Italian Quarterfinal Showdown

Lorenzo Musetti celebrates during his US Open fourth-round victory. After the match, Musetti declared, “I want to beat the No. 1 in the world,” as he set his sights on a showdown with fellow Italian Jannik Sinner.

Next up is a quarterfinal clash with compatriot Lorenzo Musetti, their first Grand Slam meeting. Sinner was quick to praise his countryman’s talent:

“Italian tennis is in great form. Lorenzo is one of the biggest talents we have,” he told reporters (Reuters).

For Italy, it marks a proud moment: two players from the same generation carrying the nation’s flag deep into a major tournament.

A Statement of Intent

Beyond the statistics, this performance reinforced Sinner’s reputation as one of the most reliable hard-court players of his era. Bublik, known for his flamboyant style, even described Sinner as “AI-generated” — a nod to his machine-like precision (News.com.au).

For Sinner, though, the goal is simple: defend his US Open crown. And judging by this 81-minute demolition job, the path to the title may well run straight through him.
