The Female Yokozuna

.
Yokozuna (= Grand Champion) is the highest Sanyaku (= Championship) rank and attained only by players who occupied a dominant position in the sport. The players listed below all (i) won back-to-back Grand Slam titles, or (ii) achieved equivalent results over three tournaments, such as two wins interrupted by a final or semifinal, and/or (iii) won five grand slam tournaments over the course of their careers. Dai-Yokozuna are Yokozuna who distinguised themselves even within this elite group, typically by winning 10 or more grand slam tournaments. Billie Jean King meets this criterion once the pre-open era is also considered. Moncia Seles is considered a Dai-Yokozuna, as arguably only a violent physical attack--that interrupted her career for several years--prevented her from winning 10 (or more) slams. The table entries are discussed in detail below.

1/ Since the beginning of the Open era.
2/ Court and King had major achievements also before the open era that are not reflected in this table's statistics.

Yokozuna promotions are rare; on average there has been one about every three years. The largest gap of more than 7 years was between Justine Henin's promotion in 2003 and Kim Clijsters' in 2011.

The table also shows important differences in the careers of the Yokozuna. Chris Evert, Martina Navratilova, Steffi Graf, and Serena Williams have the most impressive statistics; they would be joined by Margaret Court if the pre-open era would be considered as well. Serena Williams won the most grand slam titles with 23, but Chris Evert reached more finals and semi-finals, which gives her the edge in terms of total career points - a simple measure that allocates 4 points to a grand slam title, 3 points to a (lost) final, 2 points to a semifinal, and one point to a quarterfinal. Evert also holds the record for the most tournament participations as an active Yokozuna (73), but Martina Navratilova - who spent a long time at Ozeki before being promoted to the highest rank - had the most Sankayku-rank tournament entries with 81, spanning a period of more than 20 years (!).

The quickest promotion from Grand Slam debutant to Yokozuna was Monica Seles' with only 9 tournaments (little over 2 years). The slowest advance has been Kim Clijsters', who took a baby-break as a long-standing Ozeki in 2006, to come back in 2009 and advance to Yokozuna level in 2011. Jennifer Capriati and Naomi Osaka leapfrogged Ozeki level and went straight from Sekiwake to Yokozuna, by winning their first two grand slam titles back-to-back. By contrast, Maria Sharapova, Martina Navratilova and Arantxa Sanchez Vicario spent long stretches of their careers at Ozeki before they finally attained the highest rank.
