Lleyton Hewitt has been seeded sixth for Wimbledon, which gets underway next week.

Wimbledon still uses a discretionary system to arrange its seeds rather than allocating them according to ranking, with players promoted or relegated according to their prowess on grass courts.

Hewitt, a past Wimbledon champion who won on grass at Queens last weekend, has been moved above James Blake and Nikolay Davydenko in the seedings, even though they are ranked higher.

Reigning champ Roger Federer is the No.1 seed, and Rafael Nadal No.2, with the Spaniard's mediocre grass record not enough to counteract the massive rankings points lead he and Federer have over the rest of the men's field.

There is less discretion for the Wimbledon committee in the women's seedings, with world No.1 Amelie Mauresmo given the top seed for next week's event, ahead of Belgians Kim Clijsters and Justine Henin-Hardenne.

Hewitt is the only Australian among the 32 men's and 32 women's seedings.

Australian Samantha Stosur and her partner Lisa Raymond have been given the top seed for the women's doubles after winning at two of the past three grand slams.

Hewitt and American Andy Roddick are the prime beneficiaries of the formula used to decide the men's seedings.

Hewitt, who rose to 9th in the world rankings after winning at Queen's for the fourth time, will be boosted by his high seeding which augurs well for his chances of adding another Wimbledon title to the one he won in 2002.
