BARCELONA (Agencies) - Rafael Nadal opened his bid for a sixth Barcelona Open title with a dominant 6-1, 6-1 win over Daniel Gimeno Traver on Wednesday. The top-ranked Nadal hammered his fellow Spaniard with hard groundstrokes, cruising to victory after breaking Gimeno Traver's first two service games. Nadal, who sat out last year's event after winning five straight titles from 2005 to 2009, will face Santiago Giraldo of Colombia in the third round of the outdoor clay court event. Earlier, fourth-seeded David Ferrer made quick work of Carlos Berlocq to win 6-2, 6-2, and will meet Victor Hanescu, after the Romanian player beat 14th-seeded Kevin Anderson 6-4, 6-4. Two-time finalist Ferrer saved two break points to hold his serve in the third game, while Berlocq struggled with his serve throughout the first set, committing four double faults. In the second set, Ferrer also saved the only two break points he faced while breaking twice for an easy win on the outdoor clay court. The 2001 champion Juan Carlos Ferrero downed lucky loser Mischa Zverev, who took the place of the injured Andy Murray, 6-4, 7-5. The former No. 1 hit three aces in his second match since returning to the court after undergoing wrist and knee surgery in October. "I was a little worse physically due to being tired from yesterday, but I held up well and came out with the win," said Ferrero, who will play Simone Vagnozzi in the next round after the Italian bounced the 16th-seeded Juan Monaco 6-3, 6-2. Also Japan's Kei Nishikori downed lucky loser Rui Machado of Portugal 6-1, 6-4.
