Not sure of actual WTA rankings, but she was seeded at several slams
in '98-99.
1998 FRA (13), WIM (12), USA (15)
1999 AUS (12), WIM (17)
Her YE ranking in 1998 was 13 and it was 12 in 1999. So probably 12,
which is not far from top 10.
Some newspapers mentioned Venus, Hingis & Kournikova as the new young
stars - the tennis Spice Girls!
