LONDON (AFP) Rafael Nadal showed no signs of a hangover from his French Open triumph as the Spaniard defeated Marcos Daniel 6-2, 6-2 in the second round at Queens Club here on Wednesday. Nadal underlined his dominance on clay with a fifth Roland Garros crown in Paris on Sunday, but his celebrations must have been fairly muted judging by this ruthless demolition of Daniel at the pre-Wimbledon warm-up event. Just three days after that final victory over Robin Soderling, which lifted Nadal into first place in the ATP world rankings, the 24-year-old, who received a first-round bye here, was back in action under grey skies in west London. Severe tendinitis in both knees last year robbed Nadal of the chance to defend the Queens and Wimbledon titles he won in 2008, so this was his first competitive match on grass since he defeated Roger Federer in one of the All England Clubs greatest finals two years ago. With his injury problems behind him, Nadal has been revitalised over the last few months and he swept through the claycourt season in imperious fashion, winning titles in Monte Carlo, Rome and Madrid before his latest French Open success. He reeled off 22 successive victories during that run and Daniel, a Brazilian ranked 112th and making his first appearance at Queens, was no match for the top seed as he extended the winning sequence to 23. Nadal took no time at all to find his feet again on grass as he unleashed two ferocious winners from the back of the court to break in Daniels first service game. The Spaniard was completely in control after that as he cruised through the first set. A rain shower halted Nadals progress early in the second set but he quickly delivered the knockout blow after the resumption as he broke Daniel to take a 4-2 lead. That shattered the Brazilians resolve and Nadals blistering forehand winner secured a meeting with Denis Istomin, the Uzbek 16th seed, who defeated Jamaicas Dustin Brown 7-6 (9/7), 6-4 in the second round. Nadal admitted he was relieved to be able to have got straight back into the winning routine after a draining two weeks in Paris. After the final, doing press, doing a little bit of celebration and then coming back to London, I was really tired on Tuesday so I practised very bad, Nadal said. But during this match I felt well. I was returning well and thats the most difficult thing for me. The French Open is still on my mind because it was an emotional moment for me. But Im happy to be playing on grass again because I enjoy the challenge of making the transition. Novak Djokovic, the second seed and former Australian Open champion, was never troubled as he reached the third round with a 6-3, 6-3 win over Italys Paolo Lorenzi. The Serbian world number three has been affected by illness this year, but he made a solid opening to his grasscourt campaign after breaking early in both sets. Nadals compatriot and close friend Feliciano Lopez, the eighth seed, eased into the third round with a 6-2, 6-4 win over Bulgarian wildcard Grigor Dimitrov. Lopez faces Frances Julien Benneteau next after the ninth seed beat South Africas Kevin Anderson 7-5, 6-3. Mardy Fish is the next opponent for defending champion Andy Murray after the American saw off 13th seed Santiago Giraldo 7-6 (7/5), 6-2. Israels Dudi Sela, the 14th seed, won his clash with Gilles Muller 7-5, 6-2 and plays four-time champion Andy Roddick in the third round. Sam Querrey, the seventh seed, defeated his fellow American Robby Ginepri 7-6 (7/4), 6-2 to earn a clash with Spains Marcel Granollers, who thrashed Marc Gicquel 6-1, 6-4.
