<p>2007 and 2009 champion Nadal is hoping that his odd-year title luck will continue, as he plays with no sign of the hamstring injury that led to an early loss six weeks ago at the Australian Open.<br /><br />The top seed improved to 28-4 at the desert event as he beat number 105 Sweeting, a rerun of a victory for the seed from Melbourne. He next plays Indian Somdev Devarman who beat Belgian Xavier Malisse 6-1, 3-6, 7-6 (7-5).<br /><br />"Nothing was impressive, but I played solid," Nadal said. "I didn't have any big mistakes. In general, I am happy with the serve, happy with the backhand. The forehand is always is my best shot, and I need to be aggressive to have chances to have a good tournament."<br /><br />German Philipp Kohlschreiber produced the biggest upset so far, knocking out fourth seed Robin Soderling 7-6 (10-8), 6-4. Kohlschreiber now stands 4-1 in the series with the Swede, who has played the last two Roland Garros finals but was suffering with an existing ankle injury.<br /><br />"I am happy about my victory," Kohlschreiber said. "(Soderling) was on court, he played. Maybe he didn't have his best day, and so, but still, I am lucky to be through, I think." Soderling's defeat was only his second of the season, on which he now stands a 19-2 with three titles, the most on the ATP.<br /><br />"I think I lost the match when I decided to go on court, because today I shouldn't have done that," said Soderling. "Sitting here after the match, it feels like I couldn't give my 100 per cent."<br /><br />The Swede said he hurt his ankle near the end of a Davis Cup rubber a week ago, then was sick in bed with fever for five days. "It gets a little bit worse when I play, but I hope today I didn't make it too much worse. Hopefully it will be fine."<br /><br />Donald Young, a winner over fifth seed Andy Murray in the second round, was crushed by Spaniard Tommy Robredo 6-0, 6-4. Juan Del Potro won his eighth straight match to improve to 16-4 in 2011 as he beat Alexandr Dolgopolov 7-6 (7-3), 6-3.<br /><br />The Argentine who won the 2009 US Open has rebounded from an injury-marred 2010 over the last month, surging from 484th to 90th in three weeks and becoming the huge threat he once was after a title in Delray Beach.<br /><br />On the women's side, top seed Caroline Wozniacki continued her no- drama run through the field, defeating Maria Martinez Sanchez of Spain 6-1, 6-3. The Danish winner had a challenge as she faced one of the rare serve-and-volley players in the game.<br /><br />"I'm happy to be through, I knew that this was not going to be an easy one," Wozniacki said. "I'm just looking forward to play my fourth round. I'm happy to be there. I really enjoy playing this tournament, and I'm happy to get another match."<br /><br />Eighth seed Victoria Azarenka put out Pole Ursula Radwanska 7-6 (7-3), 6-3, while Radwanska's sister, ninth-seeded Agnieszwa, defeated Russian Maria Kirilenko 6-0, 2-6, 7-5.<br /><br />Russia's Alisa Kleybanova upset Italian 13th seed Flavia Pennetta 6-3, 6-4, and 16th seed Maria Sharapova spoiled the 24th birthday of France's Aravane Rezai 6-2, 6-2.</p>
