Tennis usually offers little room for sentiment and the fall from grace for leading players is often ugly and painful.
Lleyton Hewitt and Juan Carlos Ferrero need no reminding about how difficult it can be to stay on top of this rapidly evolving sport, having both led the world rankings before sliding way back into the pack.
Hewitt against Andy Roddick and Haas against Novak Djokovic may be the best chances for a surprise in the next round, but even if this battling band of elder statesmen (by tennis standards anyways) goes no further, they have added some sparkle to the tournament.
Here's the latest Yahoo! Sports Wimbledon power rankings (previous rankings in parentheses):
1. (1) Roger Federer - how can he be stopped?
