Alexander Zverev and Flavio Cobolli both navigated grueling opening-round matches at the US Open, surviving multi-hour, five-set tests to secure their places in the second round of the tournament.
Zverev Outlasts Grievous Opening Test in New York
Top-ranked contenders faced immediate turbulence at Flushing Meadows as tournament action stretched deep into the tournament’s opening days. Alexander Zverev, world number two, was forced to dig through a demanding five-set encounter to subdue his opposition and avoid a premature exit.
According to tournament records, the German star had to expend considerable energy on the hard courts, battling through shifts in momentum that tested both his physical resilience and tactical patience. Matches during the opening rounds of the calendar’s final Grand Slam frequently produce high drama, and this contest proved no exception as unheralded pressure pushed the world number two to his absolute limits.
Cobolli Joins the Marathon Winners Circle
Italy’s Flavio Cobolli mirrored that struggle on the neighboring courts, also requiring the full distance of five sets to dismiss his first-round challenger. Ranked fifth, Cobolli demonstrated tenacious defense and timely baseline aggression during the decisive stages of the match.
The Italian player’s capacity to absorb heavy ball-striking proved critical as the match crossed multiple hours of intense competition. Observers noted that while both Zverev and Cobolli entered their respective matches as clear favorites on paper, the fierce competitiveness of the early-round fields at the US Open consistently erases ranking disparities.
Stakes and Immediate Schedule Implications
Surviving demanding opening matches places an immediate premium on physical recovery for both competitors. Grand Slam tournaments demand rigorous turnarounds, leaving players minimal time to treat fatigue and minor strains accumulated during multi-hour battles.

For Zverev, preserving energy remains paramount as he pursues a deep run through the fortnight. Cobolli faces a similar athletic challenge, needing rapid physical regeneration before stepping back onto the court for his subsequent-round assignment.
