A sore ankle meant another quick exit for Andy Roddick at the French Open.
Roddick aggravated an ankle injury and retired trailing Alberto Martin 6-4, 7-5, 1-0 in the first round on Tuesday.
Seeded fifth, Roddick lost in the opening round for the third time in six appearances at Roland Garros, and his career record in the event fell to 4-6.
Playing six days after he sprained his left ankle at the World Team Cup in Germany, Roddick moved well early in the match. But he called for a trainer after losing his serve at love to start the third set.
Roddick told the trainer he had aggravated his injury late in the second set and was unsure whether to keep playing on the heavily taped ankle.
"What do you think?" he said. "Do you think it's dangerous?"
The trainer said no, but Roddick decided to quit. He walked off Court Suzanne Lenglen to a mix of hoots, whistles and applause.
Martin improved to 3-8 at Roland Garros. The unseeded Spaniard had lost all 10 sets in his four previous matches against Roddick.
Back at Roland Garros after a five-year absence, Martina Hingis said she's relaxed but hungry to win and better than before. She looked the part, beating Lisa Raymond 6-2, 6-2.
The victory was the 32nd of Hingis' career at Roland Garros, but her first since being sidelined for three years by foot and ankle injuries.
``Somehow it didn't feel like it's that long,'' she said.
The five-time Grand Slam champion is seeded 12th and considered a title threat after winning last week at Rome, her first championship since returning to the tour in January.
She played at Roland Garros for the first time since losing to eventual champion Jennifer Capriati in the 2001 semifinals.
"Today I would probably beat the Martina back then," Hingis said. "I have weapons today -- the brains and everything, experience and more mature ... I'm really more relaxed now."
Her second-round match will be against Zuzana Ondraskova, who beat Julia Schruff 6-4, 6-2.
One potential semifinal opponent for Hingis was eliminated when No. 3-seeded Nadia Petrova lost. Two-time semifinalist Petrova, who won three clay-court tournaments this spring, was upset by Akiko Morigami 6-2, 6-2.
Morigami hit 26 winners to seven for Petrova.
No. 5 Justine Henin-Hardenne began a bid for her third title in four years by beating Maret Ani 6-3, 6-0. No. 10 Anastasia Myskina, a first-round loser last year after winning the 2004 title, defeated Sania Mirza 6-4, 6-1.
"I don't have any pressure at all," Myskina said. "So I just tried my best, and it worked."
No. 13 Anna-Lena Groenefeld, No. 15 Daniela Hantuchova and No. 19 Ana Ivanovic advanced in straight sets, as did Americans Jamea Jackson and Shenay Perry. No. 23 Tatiana Golovin of France lost to Zheng Jie 6-3, 7-6 (5).
On the men's side, No. 25 Gael Monfils of France won a matchup of 19-year-olds, beating Andy Murray 6-4, 6-7 (2), 1-6, 6-2, 6-2. Murray struggled after receiving treatment for a back injury midway through the match.
"It just feels real tight," Murray said. "I couldn't serve. It doesn't help when you're serving about 50 or 60mph."
Murray said he expects to be fine for Wimbledon.
Monfils drew jeers from center-court fans in the fourth set when he argued at length about a line call.
"You know you're acting up a little bit when your own crowd is booing you," Murray said.
