Novak Djokovic Wimbledon

Three-time Wimbledon champion Novak Djokovic has been bumped up to second seed for the 2017 edition of the tennis grand slam, starting next week. This, despite Djokovic slipping to fourth in the ATP world rankings.

The seedings, released by the All England Club on Wednesday June 28, have defending champion Andy Murray number one in the men's singles with Germany's Angelique Kerber the women's top seed.

Wimbledon differs from the other grand slams, in the men's singles at least, with previous form on grass in the previous two years coming into play to re-order the top 32 in the world rankings -- a system agreed by the ATP.

Spaniard Rafael Nadal, who won his record 10th French Open title last month, is second in the ATP rankings but will be seeded fourth at Wimbledon after a mediocre record there in recent years.

Despite winning the title twice, the 31-year-old has not progressed past the fourth round since 2011.

Roger Federer, fifth on the ATP rankings, is seeded third, which means he will avoid one of his biggest rivals for the title until the semi-finals. The Swiss is definitely one of the favourites to land the trophy.

His compatriot Stan Wawrinka, runner-up at the French Open, dropped to the fifth seed, from his world ranking of three.

The women's seeds stick strictly with the current WTA rankings. While Kerber is on top at the moment, Romania's Simon Halep could take that position if she wins the Eastbourne title this week. She is currently seeded second.
