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 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 tuneup tournaments on grass ahead of Wimbledon and slid down one place.
