^^ Not official because Makarova is still alive but I think it looks good.
To be top 20, that means you should be making the R32 at slams which Varvara is. Plus, she had a great run in the Middle East and at Madrid. Couple that with the inconsistent mess of the tour, Varvara has really come on strong. Her game has improved immensely. If she can improve her serve a little bit more and flatten out her strokes a little more she is going to be VERY tough.
Two Americans in top 20 and 3 once Venus gets a full, real schedule under her belt
