Jannik Sinner: A Prophecy from the United States Fuels the Debate

Is Jannik Sinner the undisputed king of the oldest and most prestigious Grand Slam tournament? For Rennae Stubbs, Serena Williams’ longtime coach, it’s more than just a possibility. During the “Rennae Stubbs Tennis Podcast,” the former Australian tennis player, now based in New York, named the Italian as the favorite to end his career with more Wimbledon titles than Carlos Alcaraz, Ben Shelton, Alexander Zverev, and Joao Fonseca.

“I think Jannik will win Wimbledon more times,” said Stubbs, whose comments immediately sparked debate among fans and industry insiders. “Carlos is on his level; Shelton has a slim chance because of his serve. Zverev and Fonseca? I really don’t think so, given their overall performance on grass.”

“Jannik and Carlos will battle it out for many titles in London in the coming years,” she added. “Jannik has improved tremendously on his serve; he’s aggressive and has more incisive shots. When he’s at his best, I consider him better than Alcaraz on grass. Of course, Carlos has finesse, smooth footwork, and lobs… In any case, between the two, I think Jannik has a better chance.”

Rennae Stubbs’ prediction is backed up by recent statistics. Sinner is, in fact, the defending champion for two consecutive editions, following his triumphs in 2025 and 2026, with fourteen consecutive matches won at the English Grand Slam. In this year’s tournament, Sinner defeated Miomir Kecmanovic, Nuno Borges, Jenson Brooksby, Shintaro Mochizuki, Jan-Lennard Struff, and Novak Djokovic before beating Alexander Zverev in the final with a score of 6-7, 7-6, 6-3, 6-4. This run confirms his progress on the fastest surface of the Grand Slams.

Alcaraz, on the other hand, won Wimbledon in 2023 and 2024, reached the final in 2025 (losing to Sinner), and was unable to compete in 2026 due to an injury. His absence paved the way for Sinner’s second consecutive title, although the Spaniard’s overall record in London remains impressive: two titles and an 89 percent win rate (Jannik stands at 87 percent, which is still an impressive figure).

Behind the two favorites, the U.S. coach sees only Ben Shelton as a credible dark horse, thanks to his powerful serve. The American, who arrived at Wimbledon 2026 as the fourth seed following his victory in Stuttgart, suffered a surprise first-round loss to Otto Virtanen, ranked 140th in the world, with a score of 4-6, 6-3, 7-6, 2-6, 6-7. Zverev and Fonseca, on the other hand, fail to convince Stubbs: the German has a record of 22 wins and 10 losses at Wimbledon, while the Brazilian has four wins and two losses.
