2008 in Review

.
The top players are currently fighting out the end-year tennis championship, but this year's Grand Slam tennis--and therefore the tournaments relevant for the Yokozuna Tennis--ended with the U.S. Open in September. Here is the resumee for 2008.

11 male and 13 female players held Sanyaku rank over the course of 2008. 4 male and 5 female players were High Sanyakuy (active Yokozuna or Ozeki).

7 male and 8 female players got promoted. 3 male and 3 female players climbed to to a new career-high rank: Rafael Nadal (Yokozuna), Andy Murray (Sekiwake), Jo-Wilfried Tsonga (Sekiwake), Dinara Safina (Sekiwake), Agnieszka Radwanska (Komosubi), and Jie Zheng (Komosubi). There was no new Ozeki promotion.

The title player of 2008 is shared between Roger Federer and Rafael Nadal on the mens' side. On the womens' side it goes to Serena Williams. Federer and Nadal reached all four grand slam semi-finals; Nadal's two titles contrast with Federer's one title and two lost finals. Serena Williams had a relatively weak first half of the season, but restablished herself as the women to beat with a victory at the U.S. Open and a narrowly lost final (against her sister Venus) at Wimbledon.

The retirement of 2008 was Justine Henin's surprising withdrawal from professional tennis before the French Open, leaving the Williams sisters as the only active female Yokozuna. The Williamses promptly re-took control of the scene in the second half of the year.

The promotion of 2008 was undoubtedly Rafael Nadal's elevation to Yokozuna, as a result of winning back-to-back titles at the French Open and Wimbledon. Nadal is the 15th male Yokozuna of the open era. He had been Ozeki since 2006.

Tournament-Specific Yokozuna and Ozeki

.
The Yokozuna tennis ranking criteria can be applied not only to a player's overall Grand Slam tennis career, but also to individual Grand Slam tournaments--a player winning two consecutive Wimbledon tournaments is a "Wimbledon Yokozuna", a player reaching and losing back-to-back French Open finals is a "French Open Ozeki", and so on.

Such ratings yield two insights 1/:
  • the identify the open era greats of specific tournaments, and
  • they allow to distinguish "generalists" from "specialists". A "generalist" obtained high Sanyaku ranks at all or most Grand Slam events, a "specialist" did well only at selected tournaments.

As the table below shows (much more extensive tables are linked up at the bottom), in the history of open era tennis only two players managed to become tournament specific (TS) Yokozuna at all four Grand Slams: Martina Navratilova and Steffi Graf. Six others obtained three TS Yokozuna ranks. Roger Federer, Ivan Lendl, Margaret Court and Chris Evert added a TS Ozeki rank to this tally, Stefan Edberg and Monical Seles a TS Sekiwake rank. By contrast, the Dai-Yokozuna Pete Sampras and Billie Jean King are missing from the very top of the list, as most of their triumphs came at just two tourmaments: Wimbledon and the US Open (Rod Laver and Bjorn Borg are also missing, but this owes to special factors--Laver because of his short career during the open era, Borg because he skipped the Australian Open in most years).
