Daniil Medvedev and Matteo Berrettini, Ozeki

Daniil Medvedev

Double Ozeki (=Champion) promotion in mens' tennis: Daniil Medvedev and Matteo Berrettini both crossed the "great hurdle" (this is what "Ozeki" means literally in Japanese) at the 2022 Australian open to become the 35th and the 36th male Ozeki of the open era (the sanyaku rank lists will be updated once the tournament has completed). 

Medvedev reached Ozeki by following up on his triumph at the 2021 US Open with another grand slam quarterfinal participation. By now he has even reached the semifinals; if he wins the tournament he would earn a promotion to the 19th male Yokozuna (=Grand Champion) of the open era. 

Matteo Berrettini

Berrettini plays a third consecutive successful grand slam tournament: final at Wimbledon, quarterfinals in New York, (at least) semifinal in Melbourne. Different from Medvedev, he cannot earn a Yokozuna promotion at this tournament, however.

Elsewhere in the tournament, Stefanos Tsitsipas earned re-promotion to Ozeki by reaching the semifinals after two weaker grand slam tournaments. In the ladies' game, both Serena Williams and Naomi Osaka will lose active Yokozuna status, as they failed to make a grand slam semifinal for four consecutive tournaments - Williams did not participate, Osaka went out in round 3. This will leave Ashleigh Barty as the only female player with a high sanyaku rank (Yokozuna or Ozeki) after the 2022 Australian Open.

Full updates will come once the tournament completes.
