The German star overcame both a determined opponent and the weight of his own history to secure a dramatic 6-1, 4-6, 6-4, 6-7 (5-7), 6-1 victory on Sunday, ending a long quest for one of tennis' most coveted prizes.
For years, Zverev had been regarded as a future Grand Slam champion. Yet despite winning some of the biggest titles on the ATP Tour and consistently ranking among the world's elite players, success at the sport's four major tournaments had remained frustratingly out of reach.
Having lost his previous three Grand Slam finals, the pressure was immense as he stepped onto the court as the favourite. The opportunity appeared even greater this year following the absence of some of the game's dominant forces.
World number one Jannik Sinner suffered an early exit from the tournament, while defending champion Carlos Alcaraz missed the event through injury, leaving the men's draw wide open.
Zverev appeared determined not to waste the chance.
Fast Start Gives Way to Nerves
The second seed made a blistering start, overwhelming Cobolli with powerful groundstrokes and aggressive baseline play to race through the opening set in just 35 minutes.
Although Cobolli settled into the contest and responded by claiming the second set, Zverev regained control in the third, using his superior experience and heavier hitting to edge back in front.
Yet with the championship within reach, old doubts began to surface.
The fourth set became a tense and emotional battle as Zverev struggled with nerves. He twice surrendered service breaks, produced several costly double faults, and even required electrolytes on court to combat signs of cramp.
Cobolli, meanwhile, sensed an opportunity. The Italian failed to serve out the set at 5-4 but recovered impressively after wasting a set point in the tie-break, eventually forcing the match into a deciding fifth set.
The tension was evident on both sides of the net.
Errors crept into each player's game as the pressure mounted, creating a final set that alternated between thrilling shot-making and nerve-racking moments.
Ultimately, Zverev's experience proved decisive. The German reduced his mistakes, secured an early double break advantage, and took firm control as Cobolli began to tire physically and mentally.
When the Italian sent a smash long on Zverev's second championship point, the German collapsed onto the clay in disbelief.
Overcome with emotion, he lay on his back before covering his face and sobbing, finally able to celebrate the breakthrough moment that had eluded him throughout his career.
A Long Road to Tennis' Biggest Prize
Zverev's triumph marks the culmination of a journey that many expected to be completed much earlier.
The German was identified as a future star from his teenage years, drawing praise from some of the sport's biggest names, including Roger Federer.
Coming from a tennis family and following the path of his older brother, Mischa Zverev, Alexander quickly established himself as one of the most talented players of his generation.
With his powerful serve, athletic movement, and baseline consistency, he collected numerous ATP titles and spent much of the last decade ranked inside the world's top 10.
However, Grand Slam success repeatedly slipped through his grasp.
At various stages of his career, he found himself blocked by legends such as Rafael Nadal, Novak Djokovic, and Federer, before later facing the rise of younger stars Sinner and Alcaraz.
Technical inconsistencies, particularly on his second serve, and an occasional tendency to become passive in high-pressure matches also contributed to his frustrations.
After three defeats in major finals, questions had begun to emerge about whether he would ever fulfill his enormous potential on the sport's biggest stage.
In Paris, he finally delivered the answer.
Cobolli's Breakthrough Signals Bright Future
Although defeat denied him a dream title, Cobolli's performance confirmed his emergence as one of tennis' most exciting young talents.
Few observers expected the 24-year-old Italian to reach the championship match. Prior to this year's tournament, he had never advanced beyond the third round at Roland Garros.
His run to the final became one of the stories of the tournament, showcasing a game built on powerful baseline strokes, athletic movement, and impressive variety.
While nerves appeared to affect him during the opening stages of the final, Cobolli grew into the contest and repeatedly demonstrated the qualities that carried him through the draw.
The Italian believes the experience will serve as a launching pad for greater achievements.
"I started playing when I was young and I never expected this kind of result," Cobolli said.
"Now that I'm here, I just want to make something special possible.
"For me, it's not done, it's only the start."
His words reflected the optimism surrounding his future, even as Zverev celebrated the biggest victory of his career.
For the German, however, Sunday belonged to redemption. After years of carrying the burden of expectation, enduring heartbreak in previous finals, and watching opportunities slip away, he finally secured the Grand Slam title that many believed was only a matter of time.
Now, with the first major trophy finally in his hands, Zverev's place among the game's modern champions is secure.
