The 2025 US Open battle ultimately was less tense than many imagined when Alcaraz defeated Jannik Sinner in four sets. How did the Spanish player manage to overcome a Sinner who seemed invincible?
In tennis, the term "evolution of the game" is frequently discussed. Rackets, strings, forehands, backhands, movement techniques, playing styles, coaching staff, and electronic line-calling systems have all experienced major changes or substantial upgrades over the 57 years of the Open Era.
Carlos Alcaraz and Jannik Sinner are the newest "evolved versions" of men's tennis. Following the legacy of the legendary trio over the past two decades, the young Spaniard and his Italian colleague have advanced the sport further. They hit with more power, move faster, slide more fluidly, and deliver winners from positions farther behind the net than anyone before. Although it is still early to include them in the GOAT (Greatest of All Time) discussion, both have proven their potential ceiling at the highest level.
However, in the US Open final where Alcaraz triumphed 6-2, 3-6, 6-1, 6-4, the decisive element was a "classic weapon" that has defined winners and losers for centuries: the serve.
Alcaraz convincingly defeated Jannik Sinner to claim the 2025 US Open title.
Alcaraz delivered 10 aces without committing a single double fault. He achieved a first-serve success rate of 61%, winning 83% of points on those serves, and secured 57% of points on his second serve. In contrast, Sinner managed only 2 aces, made 4 double faults, had a first-serve success rate of just 48%, and also won only 48% of points on his second serve.
The gap widened as the match progressed. Alcaraz regularly reached serve speeds of 130 mph, and by the fourth set, his serving was devastating. At his service game at 3-2, he closed it with two consecutive aces at 132 mph. At 4-3, he added another ace and a service winner to hold the game to love. Serving for the championship at 5-4, Alcaraz unleashed a 134 mph serve (which Sinner returned), then finished the match with a service winner at 131 mph.
On his quest for a Grand Slam title, Alcaraz played with calm confidence, as if wielding an unbeatable secret weapon. Leading 40-15 with two match points, he missed both. One powerful backhand from Sinner caused the Arthur Ashe crowd to leap to their feet. Could Sinner replicate his feat of saving match points in a Grand Slam final, as Alcaraz did at Roland Garros?
