The US tennis player Serena Williams has been seeded a lowly 28th for the US Open as tournament organisers opted to rigidly follow the current rankings rather than reward her for outstanding past performances.
Williams, the dominant figure in women's tennis over the past decade, has won the U.S. Open three times but the former world number one's ranking tumbled after spending almost a year away from the game because of health problems.
The 29-year-old returned to the courts in June and won back-to-back tournaments in California and Toronto to climb back to 29th in the world rankings after falling to 175.
She was bumped up one place for the U.S. Open after last year's champion and world number three Kim Clijsters withdrew because of injury, but officials stopped short of elevating the 13-time grand slam champion much higher.
Although the U.S. Open traditionally sticks with the world rankings, other grand slams have used their discretion to promote top players returning from injury.
Williams' sister Venus, a two-time U.S. Open champion, was not seeded at all because her current ranking is 36th.
Denmark's Caroline Wozniacki, who has never won a grand slam but was a finalist at the U.S. Open two years ago, was named top seed because she holds the number one ranking.
Russia's Vera Zvonareva, also chasing her first grand slam title after making the 2010 finals at Wimbledon and the U.S.Open, was seeded second while former world number one Maria Sharapova was third.
Victoria Azarenka was fourth followed by Wimbledon champion Petra Kvitova, French Open champion Li Na and last year's French Open winner Francesca Schiavone.
The men's seedings are due to be released tomorrow before both singles draws are made.
