Caroline Wozniacki moved up two spots in the WTA rankings to No. 13 after winning her first title of the season at the Istanbul Cup on Sunday. The win was her 22nd career title, putting her fourth for the most titles won among active players behind Serena Williams, Maria Sharapova and Venus Williams. Wozniacki was the only top 20 player in action last week, which means there was no other movement amongst the top players in the world.
Mona Barthel is back into the top 50 after winning her first title in over a year at the Swedish Open. She's now at No. 42, her highest ranking since the Paris Indoors.
- The biggest jump went to 16-year-old Ana Konjuh, who went from No. 139 to No. 116 after making her first WTA semifinal in Istanbul. In fact, she's jumped over 70 spots in the past four weeks.
- Kristina Mladenovic rose 21 spots to land at No. 81 after making the semifinals in Istanbul, where she lost in straight sets to Wozniacki. The 21-year-old Frenchwoman, who beat Li Na in the first round of the French Open, is still a long way away from her career high of No. 36.
- Casey Dellacqua didn't pick up a racket last week but she's up three spots to a new career high at No. 33. She's in good position to be seeded at the U.S. Open.
- After making her second career final at the Swedish Open, South Africa's Chanelle Scheepers is up 20 spots to No. 71.
- Silvia Soler-Espinosa continues her rankings climb, up 11 places to No. 73. The Spaniard was ranked No. 118 in mid-May and has won 15 of 21 matches since.
