<p>Champion Novak Djokovic made a triumphant return to the venue that kick-started his remarkable 2011 as the former joker of the courts emphatically demonstrated he was not prepared to cede his Australian Open crown without a fight. <br /><br /></p>.<p> Djokovic’s victory in Melbourne last year sparked a remarkable season in which he won three Grand Slam titles and compiled a 70-6 record as he finally overhauled Rafael Nadal and Roger Federer as the world number one. <br /> <br /> On Tuesday, in baking hot conditions similar to those that had tripped the 2008 champion up in his first Melbourne Park title defence, the Serb produced an emphatic 6-2, 6-0, 6-0 victory over Italian journeyman Paolo Lorenzi in 92 minutes. <br /> <br /> “It took me a couple games to get into the right rhythm,” Djokovic, who entertained the fans with some flashes of brilliance including an audacious ‘through the legs’ shot, said. <br /> “You know, the conditions are a bit difficult. Today was I think around 35 degrees, so it took a bit of time to get used to the heat,” he added. <br /> <br /> Djokovic’s fellow US Open champion, Australia’s Sam Stosur, wilted in the pressure cooker environment on Rod Laver Arena in front of local fans holding heightened expectations as she crashed to a 7-6, 6-3 loss to Romania's Sorana Cirstea. <br /> <br /> Local fans, however, did have something to cheer about when Lleyton Hewitt rattled off six successive games and come back from a 5-1 fourth set deficit to beat Germany’s Cedrik-Marcel Stebe and advance to the second round. <br /> <br /> Hewitt, a former world number one who now appears to approach matches as a man who has hired the court for four hours and is going to get his money’s worth, blew a two-set lead and failed to capitalise on Stebe requiring virtually constant treatment on his left calf muscle before he clinched victory in three hours, 58 minutes. <br /> <br /> The Australian will now face 15th-seed Andy Roddick, who beat Dutchman Robin Haase 6-3, 6-4, 6-1, though the American said that he expected the match to go the distance, despite Hewitt now being ranked 181st in the world. <br /> <br /> World number two Petra Kvitova and fourth seed Maria Sharapova were unruffled by the hot conditions with Kvitova’s ruthlessly efficient 6-2, 6-0 victory over Vera Dushevina taking a tick over one hour. <br /> <br /> Sharapova was as merciless on Hisense Arena, beating Argentina’s Gisela Dulko 6-0, 6-1 in 58 minutes. <br /> <br /> Two other title favourites, however, had to shake off early rust before running out winners. <br /> Five-times champion Serena Williams struggled to get going against Tamira Paszek of Austria before she won 6-3, 6-2 in 79 minutes. <br /> <br /> British fourth seed Andy Murray lost the first set of his match to American teenager Ryan Harrison. The 2010 and 2011 runner-up at Melbourne Park, however, got accustomed to Harrison's style of play by the second set and was untroubled thereafter in a 4-6, 6-3, 6-4, 6-2.<br /> <br /> <br /> Australian Open results<br /> <br /> First-round results on Tuesday (prefix denotes seeding): Men’s singles: 19-Viktor Troicki (Srb) bt Juan Carlos Ferrero (Esp) 4-6, 6-7 (3-7), 6-2, 7-6 (7-3), 6-2; Lleyton Hewitt (Aus) bt Cedrik-Marcel Stebe (Ger) 7-5, 6-4, 3-6, 7-5; 6-Jo-Wilfried Tsonga (Fra) bt Denis Istomin (Uzb) 6-4, 3-6, 6-2, 7-5; 12-Gilles Simon (Fra) bt Danai Udomchoke (Tha) 6-1, 3-6, 6-7 (5-7), 6-3, 6-2; 15-Andy Roddick (US) bt Robin Haase (Ned) 6-3, 6-4, 6-1; Nicolas Mahut (Fra) bt 29-Radek Stepanek (Cze) 7-5, 7-5, 6-3; 4-Andy Murray (Gbr) bt Ryan Harrison (US) 4-6, 6-3, 6-4, 6-2; 9-Janko Tipsarevic (Srb) bt Dmitry Tursunov (Rus) 5-7, 7-6 (14-12), 6-3, 6-4; 14-Gael Monfils (Fra) bt Marinko Matosevic (Aus) 7-6 (7-5), 6-3, 6-3; Ryan Sweeting (US) bt Matthias Bachinger (Ger) 6-4, 6-4, 6-2; Tatsuma Ito (Jpn) bt Potito Starace (Ita) 6-3, 4-6, 6-3, 6-4; Michael Llodra (Fra) bt Ernests Gulbis (Lat) 2-6, 6-1, 6-2, 6-2; James Duckworth (Aus) bt Juergen Zopp (Est) 6-3, 6-4, 6-4; 23-Milos Raonic (Can) bt Filippo Volandri (Ita) 6-4, 6-0, 6-2; 1-Novak Djokovic (Srb) bt Paolo Lorenzi (Ita) 6-2, 6-0, 6-0; Edouard Roger-Vasselin (Fra) bt Xavier Malisse (Bel) 7-6 (8-6) (retd); 17-Richard Gasquet (Fra) bt Andreas Seppi (Ita) 6-3, 3-6, 6-3, 6-1; 32-Alex Bogomolov Jr (Rus) bt Daniel Gimeno-Traver (Esp) 6-3, 6-2, 6-4; 24-Kei Nishikori (Jpn) bt Stephane Robert (Fra) 6-1, 7-6 (9-7), 6-0; Santiago Giraldo (Col) bt Matteo Viola (Ita) 6-4, 6-2, 6-1; 5-David Ferrer (Esp) bt Rui Machado (Por) 6-1, 6-4, 6-2; Philipp Petzschner (Ger) bt Lukas Rosol (Cze) 6-0, 6-0, 6-2. <br /><br /> Women’s singles: 12-Serena Williams (US) bt Tamira Paszek (Aut) 6-3, 6-2; 21-Ana Ivanovic (Srb) bt Lourdes Dominguez Lino (Esp) 6-0, 6-3; Zheng Jie (Chn) bt Madison Keys (US) 6-2, 6-1;18-Svetlana Kuznetsova (Rus) bt Chanelle Scheepers (SA) 6-3, 3-6, 6-0; Urszula Radwanska (Pol) bt Alison Riske (US) 6-4, 1-6, 6-2; Stephanie Dubois (Can) bt Elena Vesnina (Rus) 6-4, 1-6, 6-4; Michaella Krajicek (Ned) bt Kristina Barrois (Ger) 6-3, 7-6 (15-13); Ekaterina Makarova (Rus) bt Tamarine Tanasugarn (Tha) 6-0, 2-6, 6-0; 7-Vera Zvonareva (Rus) bt Alexandra Dulgheru (Rom) 7-6 (7-4), 6-7 (5-7), 6-3; 9-Marion Bartoli (Fra) bt Virginie Razzano (Fra) 7-5, 6-0; Sorana Cirstea (Rom) bt 6-Samantha Stosur (Aus) 7-6 (7-2), 6-3; 23-Roberta Vinci (Ita) bt Alexandra Cadantu (Rom) 6-0, 6-1; 25-Kaia Kanepi (Est) bt Johanna Larsson (Swe) 6-2, 6-4; Jamie Hampton (US) bt Mandy Minella (Lux) 6-1, 6-1; 4-Maria Sharapova (Rus) bt Gisela Dulko (Arg) 6-0, 6-1; Jelena Dokic (Aus) bt Anna Chakvetadze (Rus) 6-2, 6-1; 17-Dominika Cibulkova (Svk) bt Magdalena Rybarikova (Svk) 6-3, 6-1; Greta Arn (Hun) bt Rebecca Marino (Can) 6-4, 6-2; 14-Sabine Lisicki (Ger) bt Stefanie Voegele (Sui) 6-2, 4-6, 6-4; Carla Suarez Navarro (Esp) bt Irina Begu (Rom) 6-1, 7-5; 15-Anastasia Pavlyuchenkova (Rus) bt Klara Zakopalova (Cze) 7-6 (7-5), 6-1; 27-Maria Kirilenko (Rus) bt Jarmila Gajdosova (Aus) 6-4, 6-2; 2-Petra Kvitova (Cze) bt Vera Dushevina (Rus) 6-2, 6-0.</p>
