Nursing a sore shoulder, Jelena Jankovic won one point with broken strings, another after falling down and the last one despite blowing a big lead. Ana Ivanovic had a much easier time, sweeping every game. And when the tennis turned tense for Novak Djokovic, he defiantly pounded his chest and whacked winners. In succession on center court, the three Serbs advanced Sunday to the quarterfinals at the French Open. The No. 3-seeded Jankovic twice received treatment on her shoulder, lost four consecutive games after reaching match point and still managed to beat No. 14 Agnieszka Radwanska 6-3, 7-6 (3). The No. 2-seeded Ivanovic, runner-up at Roland Garros last year, returned to the quarterfinals with a 6-0, 6-0 victory over Petra Cetkovska. Djokovic twice overcame love-40 deficits to hold serve, banging his chest with his fist the second time, and beat No. 18 Paul Henri-Mathieu 6-4, 6-3, 6-4. Seeded third, he'll next play 19-year-old Ernests Gulbis of Latvia, who reached his first Grand Slam quarterfinal by beating Michael Llodra 6-4, 7-6 (4), 6-3. Three-time defending champion Rafael Nadal returned to the quarterfinals by beating fellow Spaniard Fernando Verdasco 6-1, 6-0, 6-2. It was Nadal's most lopsided victory yet at Roland Garros, where he's 25-0. On Tuesday – his 22nd birthday – Nadal will play yet another Spaniard, No. 19 Nicolas Almagro, who beat Jeremy Chardy 7-6 (0), 7-6 (7), 7-5. The two women who upset the Williams sisters Friday were eliminated in their next match. No. 27-seeded Katarina Srebotnik lost to No. 10 Patty Schnyder 6-2, 6-4. No. 26 Flavia Pennetta lost to 19-year-old qualifier Carla Suarez Navarro 6-3, 6-2. Jankovic and Ivanovic are one round from an all-Serb showdown in the semifinals. But health issues put Jankovic's prospects in doubt. She blamed her shoulder pain on a recent bout of swelling in her right forearm. Leading 2-1 in the second set, Jankovic called for treatment and winced as a trainer massaged her shoulder near her neck. Some of her shots lacked their usual punch thereafter, but Jankovic built a 5-2 lead thanks to some shaky play by Radwanska. Serving in the next game, Jankovic reached match point three times but failed to hold, and Radwanska took advantage of the reprieve to mount a comeback. She scrambled to stay in the set. At 5-5, she slipped and fell 10 feet behind the baseline, quickly rose to remain in the rally and won the point when Radwanska pushed a backhand wide. In the next game, Jankovic floated a forehand winner cross-court after her strings popped, helping her to hold serve for 6-all. Radwanska committed five unforced errors in the tiebreaker, including an errant backhand to end a 28-stroke rally on the final point. On Tuesday, Ivanovic will face Schnyder for a berth in the semifinals. Jankovic will have a day to recuperate before she plays Suarez Navarro, the first qualifier to reach the women's quarterfinals at Roland Garros since Petra Mandula in 2001. – AP __
