On Monday, Serena Williams will become the seventh player in WTA Tour history to hold the No.1 ranking for 100 or more weeks, joining Steffi Graf (377), Martina Navratilova (332), Chris Evert (260), Martina Hingis (209), Monica Seles (178), and Justine Henin (117). Serena will enter Roland Garros as the top-ranked player even if current No. 2 Caroline Wozniacki wins all the singles titles leading up to the French Open.

Meanwhile, 18-year-old Melanie Oudin, who is ranked a career-high No. 31, is trying to become the first American woman outside of the Williams sisters to be a seeded at a Grand Slam event since Lindsay Davenport was seeded No. 10 at the 2006 U.S. Open.—M.C.
