Last year's runner-up Andy Roddick and French Open champion Rafael Nadal were straight-set winners on Tuesday, while heavy English crowd favorite Tim Henman had to overcome a two-sets-to-love deficit in opening-round action at Wimbledon. The second-seeded Roddick dismissed Czech Jiri Vanek 6-1, 7-6 (7-4), 6-2 on Court 1 at the All England Club. The big-serving American advanced with the help of 14 aces and six breaks of Vanek's serve. The 2003 U.S. Open champion Roddick, who lost to Roger Federer in four sets in last year's Wimbledon finale, titled on grass at London's Queen's Club two weeks ago. Roddick's second-round opponent will be Italian lucky-loser Daniele Bracciali, who snuck past 6-foot-10 Croat Ivo Karlovic in five sets, including 12-10 in the fifth. Karlovic set a Wimbledon record and tied the ATP mark (Joachim Johansson) with 51 aces in the setback, while Bracciali added 31 in an 82-ace affair. The fourth-seeded Nadal improved to 25-1 in his last 26 outings by blasting American Vincent Spadea 6-4, 6-3, 6-0. The 19-year-old Nadal won 24 straight matches at one point, all on clay, including a victory over Argentine Mariano Puerta in the French Open final three weeks ago. The Spanish sensation lost his winning streak on grass against German Alexander Waske in Halle, Germany the week after Roland Garros. Nadal will meet Luxembourg's Gilles Muller in the second round. Finland's Jarkko Nieminen jumped out to a 6-3, 7-6 (7-5) lead against Henman before the veteran Brit mounted his comeback on Centre Court. The sixth seed claimed the last three sets in 6-4, 7-5. 6-2 fashion to stave off the lefthanded Nieminen, who beat an injured Andre Agassi in the first round at Roland Garros four weeks ago. The four-time Wimbledon semifinalist Henman, who advanced on Day 2 despite scattering 55 unforced errors, went out in the quarterfinals here in each of the last two years. The 30-year-old Henman overcame a two-sets-to-love deficit for the fourth time in his career. Henman will face Russian Dmitry Tursunov in the round of 64. Twelfth-seeded Swede Thomas Johansson handled Czech Bohdan Ulihrach 6-3, 6-2, 6-2, 14th-seeded Czech Radek Stepanek stopped American Robby Ginepri 6-7 (5-7), 6-3, 6-4, 6-2 and 15th-seeded Argentine Guillermo Coria moved on with a 6-1, 6-2, 6-2 shellacking of German Tomas Behrend. Michael Llodra was leading ninth-seeded fellow Frenchman Sebastien Grosjean 6-3, 5-7, 6-4, 6-7 (5-7), 4-3 when their match was suspended until Wednesday. Other seeded winners on Day 2 were No. 18 Argentine David Nalbandian, No. 27 Frenchman Richard Gasquet, No. 28 Czech Jiri Novak and No. 33 Belgian Olivier Rochus. The 2002 Wimbledon runner-up Nalbandian brushed aside Dutchman Raemon Sluiter 6-2, 6-2, 7-5. Upsets came when Guillermo Garcia-Lopez leveled 17th-seeded fellow Spaniard David Ferrer 6-3, 6-2, 7-6 (9-7); Serb Janko Tipsarevic beat 19th-seeded German Tommy Haas 6-2, 2-1, retired; Austrian Jurgen Melzer tripped up 20th- seeded Croat Ivan Ljubicic 6-4, 6-4, 6-4; Russian Igor Andreev overcame 30th- seeded Swede Robin Soderling 6-7 (3-7), 7-5, 6-1, 7-5; and Aussie Wayne Arthurs erased 32nd-seeded Italian Filippo Volandri 6-3, 6-4, 6-4. Several other players recorded first-round wins, including Belarusian Max Mirnyi, Frenchman Fabrice Santoro and French Open quarterfinalist Victor Hanescu. Men's second-round action will commence here on Wednesday, including matches for the two-time defending champion Federer, 2002 winner Lleyton Hewitt and Australian Open winner Marat Safin. The top-seeded/world No. 1 Federer will encounter Czech Ivo Minar, as the Swiss seeks his 31st straight victory on grass. The third-seeded former world No. 1 Hewitt, this year's Aussie Open runner-up to Safin and last year's U.S. Open runner-up to Federer, will meet Czech Jan Hernych. The fifth-seeded Safin, who is 11-1 in Grand Slam action this year, should have his hands full with 2003 Wimbledon finalist Mark Philippoussis.
