PARIS, France - Serena Williams, Maria Sharapova, Victoria Azarenka and Agnieszka Radwanska - all still alive at the French Open - are assured of continuing to occupy the Top 4 spots on the WTA Rankings when the fortnight is over.

Though the order of those four has changed quite a few times since Williams replaced Petra Kvitova in the Top 4 on July 9, 2012, those same four players have been within the Top 4 ever since.

How does that compare to the other longest streaks with the same four players in the Top 4 in recent memory? Here is a list of the longest such streaks since 1990:
