When Carlos Alcaraz overcame defending US Open champion Jannik Sinner in the final at Flushing Meadows, he claimed his 10th victory in their head-to-head.

In an enthralling performance at Arthur Ashe Stadium, Alcaraz defeated Sinner in four sets on the Italian’s preferred surface, winning 6-2, 3-6, 6-1, 6-4 to hoist a sixth Grand Slam title.

The Spaniard, now tied with Boris Becker and Stefan Edberg for Open Era major crowns, has beaten the 24-year-old in six of their last seven clashes, with his sole defeat coming in the Wimbledon final.

With some fans worrying about the already iconic rivalry becoming one-sided, Serena Williams‘ former coach, Rick Macci, has no doubts about Sinner‘s ability to battle past the new world number one.

In a post on X, Macci said: “Sinner does not have to change anything but his socks.

“He just needs to keep adding subtle microscopic decisions into match play at certain moments to have Carlos thinking.

“But at the end of the day, 99.9% of his game is on another planet, and his mind is like granite.”

Before his triumph at Wimbledon, Sinner’s last victory against Alcaraz came at the China Open in 2023.

Each of their last five meetings have come in tour-level finals, four of which the ATP number two has walked away empty-handed.

Carlos Alcaraz’s 2025 victories against Jannik Sinner

Their first match in 2025 came in the final of the Italian Open, which marked Sinner’s first tournament back in action after his three-month ban from tennis.

Alcaraz emerged victorious in Rome and followed it up with a comeback win in the championship match at Roland Garros, after surviving three match points.

Sinner finally snapped his near two-year-long losing streak against the 22-year-old at Wimbledon to claim a maiden title at the All England Club.

After their Cincinnati final clash ended in a walkover, Alcaraz won their fifth bout of the season in New York following a dominant US Open campaign.
