BARCELONA — Rafael Nadal restored the balance of clay power at the Barcelona Open Wednesday with a 6-4, 6-2 win over Carlos Berlocq after top-seeded compatriot David Ferrer was eliminated by Dmitry Tursunov. Nadal, seeded second for the first time ever behind Ferrer, still needed six match points to see off persistent Argentine Berlocq, whom he had beaten on Brazilian clay two months ago. Earlier, Russian qualifier Tursunov stunned Ferrer 7-5, 3-6, 6-1 in a major second-round upset. Nadal may have still been feeling the effects of his Monte Carlo final loss at the weekend to Novak Djokovic, a defeat which denied him an historic ninth consecutive title in the principality. Nadal owns bragging rights in Barcelona after winning seven titles in eight editions and posting a 36-1 lifetime record at the Catalan venue. Tursunov moved into a third-round encounter with Brazilian 16th seed Thomaz Bellucci. Canadian fifth seed Milos Raonic made an easy start over Eduardo Roger-Vasselin of France 6-4, 6-2, as the North American made up for a disappointing loss last week in the Monte Carlo second round. Argentine Juan Monaco, seeded seventh, crushed Australian number one Bernard Tomic 6-0, 6-2 while Slovak 11th seed Martin Klizan beat Albert Montanes 6-3, 6-4 and veteran Spanish clay campaigner Tommy Robredo continued to find flashes of his best form in a defeat of Bulgarian young gun and 14th seed Grigor Dimitrov 7-5, 6-1. Marcel Granollers beat Blaz Kavcic of Slovenia 6-3, 6-1. Wozniacki upset In Stuttgart, Caroline Wozniacki lost in the first round of the Porsche Grand Prix Wednesday, falling to Carla Suarez Navarro of Spain 7-6 (6), 6-1. The former top-ranked Dane squandered a 3-0 lead in the first set and never recovered after losing the tiebreaker. Also, Petra Kvitova of the Czech Republic beat wild-card entry Annika Beck of Germany 7-5, 6-7 (0), 6-3 after breaking serve for the second time in the final set for a 5-2 lead, and Lucie Safarova of the Czech Republic beat Mona Barthel of Germany 6-4, 6-1. — Agencies
