The 30 plusses are doing well.
Federer still ranked world #3.
Ferrer still ranked world #4 and still making Masters finals.
Haas taking out the world #1 in Miami.
Robredo taking out the guy who almost took out the world #1 at the AO.
Stepanek still helping his country to win the Davis Cup.
In tennis terms, maybe 30 is the new 20?
After all, most of the 20 year-olds still play like juniors!
