Wimbledon: Milos Raonic seeded 7th, Eugenie Bouchard 12th

​Eugenie Bouchard was the runner-up at Wimbledon last year, but she heads into this year's tournament well down the seedings at No. 12 as a season marked by disappointing results continues.

The Westmount, Que., native, who insists she will play at the All England Club despite retiring with an abdominal injury Wednesday at Eastbourne, has just three wins since her quarter-final loss to Maria Sharapova at the Australian Open in January.

On the men's side, fellow Canadian Milos Raonic, who reached the semifinals at Wimbledon last year, is ranked seventh.

Earlier this month, the Thornhill, Ont., native returned from surgery on a pinched nerve in his foot to play at the Aegon Championship, losing to Frenchman Gilles Simon in the quarter-finals.

Five-time winner Serena Williams is the top seed on the women's side, followed by defending champion Petra Kvitova, Simona Halep, Maria Sharapova, and Caroline Wozniacki. The rest of the top 10 are Lucie Safarova, Ana Ivanovic, Ekaterina Makarova, Carla Suarez Navarro, and Angelique Kerber.

Defending champion and top-ranked Novak Djokovic is seeded No. 1. He is followed in the men's seedings by seven-time champion Roger Federer, 2013 winner Andy Murray, French Open champion Stan Wawrinka, and Kei Nishikori. Tomas Berdych, Milos Raonic, David Ferrer, Marin Cilic and Rafael Nadal round out the top 10.

For the two-time champion Nadal, this is his lowest seeding ever at the All England Club and means the Spaniard could face top contenders as early as the fourth round, and one of the top four seeded players in the quarter-finals.

Injuries, poor results

Nadal, who won Wimbledon in 2008 and 2010, dropped in the rankings after injuries and poor results.

He lost in the first round of Queen's Club last week, after winning on grass in Stuttgart the previous week.

Nadal's previous lowest seeding at Wimbledon was No. 5 in 2013. Other than that, he's always been among the four, except when he was unseeded in his first appearance at Wimbledon in 2003.

Despite his drop in form and low seeding, Nadal is still considered among the top group of title contenders, behind Djokovic, Murray and Federer.

There are also dangerous floaters outside the top 10, including No. 11 Grigor Dimitrov, No. 13 Jo-Wilfried Tsonga, No. 17 John Isner, No. 18 Gael Monfils, and No. 23 Ivo Karlovic

The All England Club stuck mainly to the rankings in its list of seedings for the grass-court Grand Slam, which starts Monday.

Until 2002, the All England Club had its own seeding committee and used its discretion to seed players outside the rankings. Since then, it has used a "surface-based system" in agreement with the ATP that reflects grass-court results, and doesn't veer much from the rankings.

The Wimbledon draw will be on Friday.
