-- Looking wan and weary, Justine Henin-Hardenne on Tuesday became the first French Open champion to follow her triumph with a first-round loss at Wimbledon, falling to Eleni Daniilidou of Greece, 7-6 (10-8), 2-6, 7-5.

The Belgian had more than a hand in her own demise, double-faulting 11 times. She was bothered throughout by a hamstring injury, she explained afterward, and conceded that she suffered for not having played a tune-up match on grass -- a surface that demands radically different skills than her beloved clay.

But given her fragile health (she missed much of 2004 with a viral illness that sapped her strength), Henin-Hardenne can't take the risk of playing more than three consecutive weeks. And she intimated that if she is ever to win Wimbledon, the only Grand Slam to elude her, it may require choosing between the grass-court classic and the French, which she has won twice.

French Open champion Rafael Nadal, meantime, cruised past American Vince Spadea, 6-4, 6-3, 6-0. The match was easier than Nadal expected; Spadea was hampered by a sore back.

Without peer on clay, Nadal threw himself into grass-court preparations immediately after winning the French but remains humble about his prospects here -- at least this year.

"I am trying," said Nadal, 19. "I am playing good. But after tomorrow, I don't know."

American Andy Roddick, Wimbledon's No. 2 seed, also had an easy first round, dismissing the Czech Republic's Jiri Vanek, 6-1, 7-6 (7-4), 6-2. Roddick hit 32 winners to just 11 unforced errors.

Fit and in form, he's among the few deemed capable of denying Roger Federer a third consecutive Wimbledon title. But after winning the 2003 U.S. Open, Roddick has struggled to close out important matches. He's training hard, but the results haven't come. And he's apparently weary of being asked why.

"It's a tough situation to be in, to finish number two in the world and have this and that said -- people speculating about what's wrong," Roddick said in his post-match interview. "If you guys were the second-best journalists in the world, I bet you'd be pretty happy."

Roddick's 14 aces were dwarfed by the Wimbledon-record 51 aces hit by Croatia's Ivo Karlovic in his match with Daniele Bracciali of Italy. Stunningly, he lost. Bracciali won the 4-hour 17-minute marathon, 6-7 (7-4), 7-6 (10-8), 3-6, 7-6 (7-5), 12-10.

Defending Wimbledon champion Maria Sharapova needed just 58 minutes to oust Spain's Nuria Llagostera Vives, 6-2, 6-2.
