Kinboshi:
("gold star" - prize awarded to a non-sanyaku ranked competitor for beating an active Yokozuna):
- Yulia Putintseva - for beating Yokozuna Naomi Osaka in Round 1
Other noteworthy developments:
- Dai-Yokozuna Serena Williams falls again short in a Grand Slam final - her third final loss in the last five tournaments - and thus remains #2 in our merit-based Open Era ranking.
- Simona Halep jumps the Ozeki hurdle twice: by following up on her quarterfinal participation at Roland Garros with a win at Wimbledon, and by winning her second slam.
- Sloane Stephens, Madison Keys and Ashleigh Barty all lose before the quarterfinals and go kadoban - they need to reach the quarterfinals at the US Open to hold Ozeki rank.
- Kei Nishikori holds again Sekiwake rank with a quarterfinal participation. He is Sekiwake Sekiwake for a total of 7 tournaments now, equaling the record set by Goran Ivanisevic.
