Victoria Azaranka beat Serena Williams 2-1 on September 10th, 2020 at the US Open semis. She went on to beat Venus Williams 2-0 on September 16th, 2020 at the Italian Open.

The timing worked nicely for Azaranka to beat the Williams sisters within a week in 2 tournaments as she beat Serena in the second last match of the women's singles of US Open, and faced Venus on the first round of the next WTA tournament, the Italian Open. Otherwise this feat might have been easier done in just one tournament.

Given the dominant run the Williams sisters have had in the past 20+ years, I wonder had thy been beat in a week by the same player ever before in single's tournaments?

    I'm not sure this meets my minimum bar of "relevant statistic". Beat the sisters in one tournament, perhaps, but in one calendar week?

  • Well if it's happened in a tournament then it should be easier to get an answer. If no answers I'll try to scrape a source, if I find any
