Four-time grand slam champion Naomi Osaka’s name appeared on the singles entry list for Wimbledon released by the organisers on Friday but Roger Federer and the Williams sisters were not included.

Osaka said last month that she “wasn’t 100 per cent sure” she would participate at the grasscourt grand slam because of the decision by the sport’s governing bodies to strip the tournament of ranking points had reduced her motivation to play.

Wimbledon had its ranking points taken away by the ATP and WTA after the major opted to exclude players from Russia and Belarus because of Russia’s invasion of Ukraine, which Moscow calls a “special operation”.

Osaka, 24, also withdrew from Wimbledon last year after taking time off for “personal reasons” — a month after quitting the French Open when she was overwhelmed by media duties.

Meanwhile, seven-time singles winner Serena Williams and her sister Venus, a five-time singles champion at the All England Club, were conspicuous by their absence.

In the men’s draw, Daniil Medvedev was the most notable omission due to the ban imposed by the All England Club. The Russian could even return to the top of the rankings without playing at Wimbledon as Novak Djokovic will lose the points he earned by lifting the title last year. Eight-time winner Roger Federer is also not on the entry list.
