Carlos Alcaraz replaces Novak Djokovic at No. 1 ahead of Wimbledon. Iga Swiatek stays atop the WTA

Carlos Alcaraz replaced vak Djokovic at . 1 in ATP rankings on Monday, meaning 20-year-old Spaniard is expected to have top seeding at Wimbledon.

Alcaraz, reigning U.S. Open champion, is coming off first grass-court title of his career, which he won Sunday by beating Alex De Minaur in final at Queen’s Club in London, and that helped him rise one spot from . 2.

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

It is sixth time . 1 ranking has switched in 2023, most since it happened seven times in 2018.

Play begins at Wimbledon on July 3.

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

Iga Swiatek remained at . 1 — as she has for every week since first climbing to that position in April 2022 — on Monday, a little more than two weeks after she won French Open for third time. Australian Open champion Aryna Sabalenka kept her hold on . 2, and defending Wimbledon champion Elena Rybakina is at . 3. Jessica Pegula moved up to . 4, switching with . 5 Caroline Garcia.

Wimbledon’s seedings used to be based on a formula that took into account players’ recent success re and at or events contested on grass courts. But with only rankings mattering w, re is unusual situation of even last year’s results at All England Club t mattering — because ATP and WTA chose to withhold all rankings points that would have been earned at Wimbledon in 2022 to protest club’s decision to ban players from Russia and Belarus over invasion of Ukraine.

That war continues, but club is allowing Russians and Belarusians to compete this time.

Djokovic has won Wimbledon each of past four times it was held — in 2018, 2019, 2021 and 2022; tournament was canceled in 2020 because of coronavirus pandemic — and seven times in all.

“I mean, vak is main favorite to win Wimbledon. That’s obvious,” Alcaraz said. “But I will try to play at this level, to have chances to beat him or make final at Wimbledon.”

If y are indeed seeded s. 1 and 2, Alcaraz and Djokovic could meet only in championship match on July 16. At Roland Garros, Alcaraz was . 1 seed for first time at a Grand Slam tournament, while Djokovic was . 3, and y were drawn to meet in semifinals.  first two sets were terrific, but n Alcaraz faded because of full-body cramps he attributed, at least in part, to tension, and Djokovic took last two sets 6-1, 6-1 on way to trophy.

re was or major change in men’s rankings Monday, with Daniil Medvedev still at . 3, followed by Casper Ruud at . 4 and Stefas Tsitsipas at . 5. Taylor Fritz, who is from California, and Frances Tiafoe, who is from Maryland, were at s. 9-10, remaining first pair of American men in top 10 in more than a decade.
