Ana Ivanovic, Jelena Jankovic move into US Open 3rd round

Former top-ranked players Ana Ivanovic and Jelena Jankovic of Serbia are quietly into the third round of the U.S. Open with impressive performances so far.

Each has dropped just nine games through two straight-set wins. The 12th-seeded Ivanovic beat 51st-ranked Sofia Arvidsson of Sweden 6-2, 6-2 on Thursday. Jankovic, seeded 30th, defeated 115th-ranked Lara Arruabarrena-Vecino of Spain 6-4, 6-2.

Both women reached No. 1 in the world in 2008, a breakthrough year for Serbian tennis when Ivanovic won the French Open and countryman Novak Djokovic took the Australian Open.

While Djokovic has since won four more Grand Slam titles, Ivanovic and Jankovic have often struggled in the last four years.
