Kinboshi:
("gold star" - prize awarded to a non-sanyaku ranked competitor for beating an active Yokozuna):

• Chung Hyeon - for beating Dai-Yokozuna Novak Djkokovic in round 4.
• Belinda Bencic - for beating Yokozuna Venus Williams in round 2.

Other noteworthy developments:

• Dai-Yokozuna Serena Williams becomes inactive after missing her fourth grand slam tournament. A seminal or two quarterfinals within the next four slams suffice to reactivate Yokozuna status
• Jelena Ostapenko and Garbine Muguruza lost Ozeki rank. As Sekiwake-Ozeki, they still enjoy limited rank protection for one more tournament: a semifinal at the 2018 French Open would suffice for a return to Ozeki.
• Sekiwake and ex-Ozeki Stan Wawrinka lost in round 2 and loses rank protection, meaning that there is no longer a quick return path to Ozeki (other than winning the French Open)
• Ozeki Karolina Pliskova and Sekiwake Madison Keys hold rank with quarterfinal participations. Keys was one win away from an Ozeki promotion, but lost to Kerber in the quarterfinals.
• Marin Cilic moves up to Ozeki for the second time in his career, as a result of the final participations at Wimbledon 2017 and these Australian Open. His first spell, which followed the slam victory at the 2014 US Open, lasted only two tournaments.
• Carline Wozniacki's first slam victory brings her back to Sekiwake for the 7th time in her career, equaling Wendy Turnbulls' and Zina Garrison's record. Moreover, with one title, two (lost) finals and four additional semifinal participations, she is arguably the strongest career-high Sekiwake of the open era now - her stats would be befitting for an Ozeki were it not for the lack of consistency at the slams. Wozniacki earned another shot at an Ozeki promotion though, with a quarterfinal at the French Open or a seminal at Wimbledon enough to make the leap over the "Great hurdle" (this is what "Ozeki" means literally in Japanese).
• Finally, Dai-Yokozuna Roger Federer won his 20th grand slam, therefore double-earning the title "Dai" (Great) in front of his rank category "Yokozuna" (Grand Champion). A unique achievement, at least in mens' tennis. We won't call Federerer "Dai-Dai-Yokozuna", but he becomes the #1 in our open era player ranking, ahead of Rod Laver and Ken Rosewall (we know these rankings are murky and we held out for a long time, but it's time to elevate Federer).
