After having won seven of the last eight French Opens, it is silly to have Rafael Nadal enter the 2013 French Open as a fourth or fifth seed. However, that is exactly where he is headed. After missing the majority of the tournament action due to a knee injury following last year's Wimbledon, Nadal has slipped in the rankings to No. 5. He may improve to No. 4 before the French, and wherever he does sit heading into that tournament is where he will be seeded.
