In the semifinals on Friday, the top-seeded Djokovic, a 35-year-old from Serbia, will meet either No. 9 Cameron Norrie of Britain or unseeded David Goffin of Belgium. The men's quarterfinals Wednesday: No. 2 Rafael Nadal of Spain vs. No. 11 Taylor Fritz of the U.S., and Nick Kyrgios of Australia vs. Cristian Garin of Cile.
The first player into the women's semifinals was 103rd-ranked Tatjana Maria, who defeated Jule Niemeier 4-6, 6-2, 7-5 in an all-German matchup. Maria is 34, making her only the sixth woman at least that old to get this far at Wimbledon in the professional era, which began in 1968.
The others? It's quite a list: Martina Navratilova, Billie Jean King, Chris Evert, Serena Williams and Venus Williams.
This is Maria's 35th Grand Slam tournament; she only once previously had even made it as far as the third round.
She'll take on No. 3 Ons Jabeur of Tunisia or Marie Bouzkova of the Czech Republic for a spot in Saturday's final. The other women's quarterfinals: 2019 champion Simona Halep of Romania vs. No. 20 Amanda Anisimova of the U.S., and No. 17 Elena Rybakina of Kazakhstan vs. Ajla Tomljanovic of Australia.
Of the women's quarterfinalists, only Halep owns a major title (she has two).
