ranked Caroline Wozniacki's latest trip to the Family Circle Cup began a lot better than the last one ended. Wozniacki opened with a straight-set victory over American Irina Falconi Wednesday. It was only a year ago that Wozniacki had to retire from a semifinal match against Vera Zvonareva because of an ankle injury when sliding on the green clay. This time, though, Wozniacki moved like the No. 1 player in dispatching Falconi, 6-1, 6-1. Other early winners were No. 7-seeded Nadia Petrova of Russia and No. 10 Daniela Hantuchova of Slovakia. Fifth-ranked Samantha Stosur and No. 8 Jelena Jankovic, both won their opening matches. Stosur, the defending champion seeded second behind Wozniacki, topped Patricia Mayr-Achleitner, 6-1, 6-2. Jankovic, the third seed who won this tournament in 2007, overcame a windy afternoon at stadium court to take out Tamira Paszek, 6-2, 6-3. Querrey upset America's Ryan Sweeting escaped six break points in the final game to upset second-seeded countryman Sam Querrey 3-6, 7-6 (5) 6-3 in the second round of the US Men's Clay Court Championships in Houston Wednesday. There were 11 total service breaks in the match. The players broke each other in seven consecutive games, spanning from the last five games of second set through the first two games of the third. Sweeting survived 18 of 24 break points. Querrey lost three points on his serve in the tie-breaker, including a double-fault for set point. Fourth-seeded John Isner of the US downed Argentina's Horacio Zeballos 7-5, 6-3, while Teymuraz Gabashvili of Russia defeated eighth seeded Grigor Dimitrov of Bulgaria 7-6 (4), 6-3. Qualifier Ivo Karlovic of Croatia boomed over 12 aces to beat Igor Kunitsyn of Russia 6-4, 6-1. Isner served up 14 aces and did not face a break point in his match. Azarenka opens with win In Spain, top-seeded Victoria Azarenka breezed past Arantxa Parra Santonja 6-2, 6-3 in the first round of the Andalucia Tennis Experience Wednesday. Azarenka, coming off a victory at the Sony Ericsson Open, broke four times and saved four breakpoint chances at the clay-court tournament. In second-round matches, second-seeded Svetlana Kuznetsova rallied to beat Agnes Szavay 6-7 (2), 6-1, 6-2, and former No. 1 Dinara Safina ousted fifth-seeded Tsvetana Pironkova 6-3, 6-4. Sixth-seeded Klara Zakopalova defeated Lourdes Dominguez Lino 7-6 (3), 1-6, 7-6 (0), and No. 8 Sara Errani downed Kristina Barrois 6-1, 6-2. Fognini, Montanes advance In Morocco, Fabio Fognini of Italy came from 6-1, 5-2 down to beat Blaz Kavcic 1-6, 7-5, 7-5 and reach the quarterfinals of the Grand Prix Hassan II Thursday.
