Carlos Alcaraz replaced Novak Djokovic at No. 1 in the ATP rankings on Monday, meaning the 20-year-old Spaniard is expected to have the top seeding at Wimbledon.

Alcaraz, the reigning U.S. Open champion, is coming off the first grass-court title of his career, which he won Sunday by beating Alex De Minaur in the final at Queen’s Club in London, and that helped him to rise one spot from No. 2.

Djokovic, who picked up his men’s-record 23rd Grand Slam title at the French Open this month, chose not to play any tune-up tournaments on grass ahead of Wimbledon and slid down one place.

It is the sixth time the No. 1 ranking has switched in 2023, the most since it happened seven times in 2018. Play begins at Wimbledon on July 3. 

The All England Club will announce the men’s and women’s seeds Wednesday and is expected to simply follow the ATP and WTA rankings for those 32 berths in each 128-player singles draw. That would put Alcaraz and the leading woman, Iga Swiatek, in the top line of each bracket.
