Carlos Alcaraz and Jannik Sinner have taken the tennis world by storm, splitting the last eight Grand Slams between them. “I’m seeing you more than my family,” grinned Alcaraz during his victory speech after defeating Sinner in the US Open final to reclaim the World No. 1 ranking after two years. Their back-to-back finals are no coincidence: they hint at a new era of dominance. But this rivalry has sparked bigger conversations, as Roger Federer now faces bizarre backlash after calling out tournament directors over alleged Jannik Sinner bias, throwing fuel on an already blazing fire within tennis circles.
This season, Carlos Alcaraz and Jannik Sinner have turned tennis into a two-man show, splitting the year’s four Grand Slams and crafting one of the fiercest rivalries in recent memory. Each player won two majors, and remarkably, they faced each other in the finals of three of the four Slams. At Roland Garros, fans were treated to an instant classic, as Alcaraz fought from two sets down to defeat Sinner 4-6, 6-7, 6-4, 7-6, 7-6 in a five-hour marathon that now stands as the second-longest Slam final in the Open Era.
Their rivalry stayed red-hot at Wimbledon, where Sinner flipped the script and outplayed the Spaniard 4-6, 6-4, 6-4, 6-4, capturing the title on the hallowed grass. The pendulum swung back at the US Open, where Alcaraz once again stood tall, overcoming the Italian 6-2, 3-6, 6-1, 6-4. What makes this run more extraordinary is their consistency; they have now clashed in the final of the last five tournaments in which they both competed, a staggering display of dominance.

Even outside the Slams, this duel has captivated fans. In Rome, Alcaraz defeated Sinner in a thrilling clay-court final, while at the Cincinnati Open, Sinner was forced to retire mid-match due to fitness concerns, handing Alcaraz another win. Their H2H battles have become appointment viewing, and naturally, the tennis world is buzzing about how this rivalry will shape the sport’s future.

Into this heated atmosphere stepped Roger Federer, who made headlines with a bold theory about the conditions enabling this near-constant rivalry. Fresh off promoting the 2025 Laver Cup in San Francisco, the 20-time Grand Slam champion joined Andy Roddick on the Served podcast to discuss the state of the game. When asked about court speeds, Federer didn’t hold back.
“Yes,” Federer said emphatically when asked if there needed to be a course correction. He argued that court speeds have become too homogenized, forcing players into similar styles of play. “That’s why we, the tournament directors, we need to fix it. We need to have not only fast courts, but what we would want to see is Alcaraz or Sinner figure it out on lightning fast, and then have the same match on super slow and see how that matches up.”
Federer went further, reminiscing about how the ATP once counted only 12 tournaments toward rankings, which encouraged players to compete on their preferred surfaces, producing contrasting clashes. “That’s how the rankings points used to be, remember? Back in the day, only 12 tournaments counted, so everybody would play on their favorite surface. And then they would sometimes meet, and those were the best matches when you had the attacker against a retriever, and now everyone plays similar.”
The Swiss maestro finished with a pointed observation, suggesting that tournament directors intentionally slow down surfaces to favor baseline grinders like Sinner and Alcaraz. “It’s because the tournament directors have allowed with the ball speed and the court speed that every week is basically the same… So that’s what the tournament directors are thinking, like, ‘I kind of like Sinner-Alcaraz in the finals, you know? It kind of works for the game’.”
