Federer, who has a 59-match win streak on grass, is aiming for his sixth straight Wimbledon title and 13th Grand Slam championship. Ivanovic looks at add to her French Open title.
Wimbledon stuck closely to the world rankings, particularly among the women, in determining the seeding for the two-week tournament. The top seven spots in the men's list followed the rankings.
