The All England Club released the seedings Wednesday for this year's grass-court Grand Slam, which starts Monday. The top five in the ATP rankings remain in their positions: Djokovic at No. 1, followed by Murray, Federer, David Ferrer and Nadal.
The women's seedings follow the WTA rankings, with five-time Wimbledon champion Serena Williams at No. 1 and Victoria Azarenka at No. 2. Serena's sister, Venus Williams, withdrew Tuesday, citing a back injury.
Nadal slipped down the rankings after being sidelined for about seven months with a left knee injury following his surprise loss to Lukas Rosol in the second round at Wimbledon last year.
The Spaniard has won seven of the nine tournaments he has entered in his comeback including the French Open last month but he still fell to No. 5 after Roland Garros behind the man he beat in the final Ferrer.
Wimbledon's seeding order is determined using the ATP rankings and points are added for achievements in grass-court tournaments in the past 12 months. The All England Club could have moved Nadal up to No. 4 ahead of Ferrer but decided to stick to the rankings.
