French Open champions Rafael Nadal and Serena Williams are the hottest players coming into Wimbledon, which starts Monday. But the outlook for those two on the grass of the All England Club is very different.
Friday's draw will be much more significant for the men's event than for the women's tournament. Nadal is ranked only fifth at the moment, and he will be seeded No. 5 at Wimbledon, despite the formula that allows Wimbledon officials to deviate slightly from the rankings when making their seedings.
Nadal will be in line to face Roger Federer, Andy Murray or Novak Djokovic in the quarterfinals, and he might have to beat all three to win the title. Winning three consecutive matches against players who have won 24 major titles, including seven of the past 10, would be a major accomplishment, even for Nadal.
The possibility of somebody completing a Grand Slam in 2013 has already been eliminated, with Djokovic and Victoria Azarenka having won the Australian Open singles titles in January.
We'll count down the top six Wimbledon contenders for both the men's and women's singles, listing the least likely to win first and the most likely last.
