I was looking through the ATP rankings trying to see who my BOTB ranking double was (Jesse Witten), and I noticed a few players I had never heard of. So I started looking up the rankings to see how high I would go before I was able to recognize every player above a certain number. On the ATP side, I got as high as 70 (Alexander Dolgopolov of Ukraine). I'm sure I've probably seen his name before, in Kandi's Challenger thread if nowhere else, but I had no conscious awareness of this guy before now. Although I don't follow the WTA as much as ATP, I was able to recognize the top 127. The first woman who stumped me was 128 (Johanna Larsson of Sweden). How about you? How far can you go down the rankings until you meet a ???? (I used the rankings on the WTA and ATP sites for reference)
