Roger Federer recovered from an erratic start to beat Arnaud Clement 7-6 (7), 6-2 Friday and reach the semifinals of the Estoril Open. Federer will play defending champion Albert Montanes, after the fourth-seeded Spaniard defeated Pablo Cuevas 6-4, 6-3. Federer lost his serve in the opening game of the match before breaking back in the fourth. He squandered three break points in the fifth game as he repeatedly mishit backhand shots but gradually composed himself to win two service games without conceding a point. Federer broke Clement's serve in the first game of the second set when he conceded just five points on his own service. Fifth-seeded Guillermo Garcia-Lopez advanced after Alberto Martin retired with the score at 6-0, 2-0 and next meets Frederico Gil who eliminated fellow Portuguese Rui Machado 4-6, 7-6 (1), 6-3. There were upsets in both of the women's semifinals, as Arantxa Parra Santonja of Spain overcame second-seeded Sorana Cirstea of Romania 6-1, 6-4, and Anastasija Sevastova of Latvia rallied to beat No. 7 Peng Shuai of China 6-7 (6), 6-1, 6-3. Jankovic beats Serena Top-ranked Serena Williams squandered a match point in the Italian Open semifinals and lost to former No. 1 Jelena Jankovic 4-6, 6-3, 7-6 (5) on Friday. Williams served for the match twice in the third set and was broken both times, wasting a match point when she hit a backhand long at 5-4. Williams jumped out to a 5-2 lead in the tiebreaker but missed four consecutive baseline shots to hand Jankovic her second final of the year. Unseeded Maria Jose Martinez Sanchez of Spain prevented an all-Serb final Saturday when she beat another former No. 1 – Ana Ivanovic – 6-4, 6-2. Ivanovic, whose ranking has slipped to No. 58, struggled to counter Martinez Sanchez's serve-and-volley game. The 26th-ranked Spaniard also was effective with drop shots. Jankovic is aiming for her third title at the Foro Italico after winning in 2007 and 2008. She routed Serena's older sister Venus 6-0, 6-1 in the quarterfinals Friday and became only the seventh player to beat both Williams in the same tournament – joining Aranxta Sanchez Vicario, Steffi Graf, Martina Hingis, Kim Clijsters, Lindsay Davenport and Justine Henin. Clijsters is the only player to achieve the feat twice. Djokovic retires Top seed and titleholder Novak Djokovic retired with breathing problems during his quarterfinal at the Serbian Open Friday. The second-ranked Djokovic said allergies were to blame for his respiratory troubles. He pulled out after losing the first set 6-4 to fellow Serb Filip Krajinovic, an 18-year-old wild card who reached his first ATP semifinals. On Saturday, Krajinovic will play third-seeded Sam Querrey, who defeated Igor Andreev of Russia 6-3, 2-6, 6-4. Second-seeded John Isner rallied to beat Richard Gasquet of France 2-6, 7-6 (6), 6-3 for two Americans to reach the semis. Fourth-seeded Stanislas Wawrinka saved two set points in struggling past sixth-seeded Viktor Troicki of Serbia 7-5, 6-7 (3), 7-6 (6). Wawrinka will meet Isner next. Berdych bows out Philipp Petzschner of Germany upset defending champion Tomas Berdych of the Czech Republic 1-6, 6-3, 6-4 to reach the BMW Open semifinals on Friday. Top-seeded Marin Cilic of Croatia needed three sets to beat sixth-seeded Nicolas Almagro of Spain 6-4, 6-7 (2), 6-2 and stay on course for his third title of the year. Two-time runner-up Mikhail Youzhny of Russia, who lost last year's final to Berdych, eased into the last four by defeating Jiri Hajek of the Czech Republic 6-1, 6-3. Fifth-seeded Marcos Baghdatis of Cyprus reached his second semifinal of the year by beating fourth-seeded Philip Kohlschreiber of Germany 6-3, 6-4. Kohlschreiber won the tournament in 2007. Petzschner will next play the second
