Interesting Stats re Prolific Slam Winners
Navratilova won her first slam in 1978; she won her last in 1990.
Evert won her first slam in 1974; she won her last in 1986.
Graf won her first slam in 1987; she won her last in 1999.
Margaret Court won her first slam in 1960; she won her last in 1973.*
Interestingly, although Seles won her first in 1990, the last time she was even in with a shout was in 2002.
(*Whether Court's first few Australian Opens can be really counted is better debated by people who remember those times; the Australian Open was not a tournament which many of the top players entered in that period.)
The pattern? Twelve or thirteen years maximum is about as long as these great players can stretch.
If Serena wins tomorrow, she will be nine years since her first slam. That affords her three or maybe four more years, does it not?
