Advanced Baseline women's tennis rankings (May 3)

Some thoughts on this month's rankings:

There was not a lot of major movement on the women's side this month, no "Nadal moving from fifth to second" type of storyline. Serena Williams is still pretty far ahead of Victoria Azarenka, Azarenka is still further ahead of Maria Sharapova, and Sharapova is still even further ahead of everybody else. There's also a decent drop-off after No. 5. The distance between Na Li and No. 6 Caroline Wozniacki is almost the same as the distance between Wozniacki and No. 15 Maria Kirilenko. (For anybody who's watched women's tennis over the past few months, this makes sense. It's a log jam.)
We do get to welcome a new (old) member to the Top 10, however: Ana Ivanovic has maintained pretty good form in 2013, and she has risen to ninth because of it. 2011 Wimbledon champion Petra Kvitova, meanwhile, is four one-thousandths of a point away from dropping out of the Top 10.
The biggest rise in the Top 100 comes courtesy of 28-year old American Bethanie Mattek-Sands, who destroyed No. 30 Sloane Stephens (6-2, 6-0) in Charleston, then reached the finals of the indoor clay tournament in Stuttgart with mostly dominant wins over No. 45 Yanina Wickmayer (6-2, 6-1), No. 21 Sabine Lisicki (6-4, 6-2), and 2012 French Open finalist, No. 11 Sara Errani (6-0, 4-6, 6-1). She eventually fell in the semifinals to Na Li, but she is playing at a level she hadn't reached since before a 2011 shoulder injury. And her rise to No. 42 gives the United States nine players in the Top 50.
Your Top 15 Americans:
1. Serena Williams (No. 1 overall)
2. Venus Williams (No. 7)
3. Jamie Hampton (No. 29)
4. Sloane Stephens (No. 30)
5. Madison Keys (No. 32)
6. Mallory Burdette (No. 37)
7. Bethanie Mattek-Sands (No. 42)
8. Varvara Lepchenko (No. 46)
9. Christina McHale (No. 48)
10. Vania King (No. 60)
11. Lauren Davis (No. 71)
12. Alexa Glatch (No. 100)
13. Maria Sanchez (No. 115)
14. Coco Vandeweghe (No. 118)
15. Grace Min (No. 120)
Another American name to watch, by the way? Shelby Rogers. A 20-year old from Charleston, Rogers cruised through the field at the Charlottesville clay court challenger this past week, dominating Americans like Maria Sanchez and making her way into the Top 150 at No. 140.
