Sabalenka has probably just entered her prime within the past year or so. Barring major injury, on what basis do you conclude that her days of winning top tier events a la WTA 1000s and Grand Slams are soon coming to an end? What a head-scratching comment to make without any justification whatsoever.

Age is also on her side.
