PARIS -- James Blake has lost in the first round of the French Open to a qualifier making his Grand Slam debut.
The 15th-seeded Blake was upset 7-6 (6), 7-5, 6-2 on Tuesday by 93rd-ranked Leonardo Mayer of Argentina.
Blake has never been past the third round at Roland Garros. The American made more than twice as many unforced errors as Mayer.
Lapentti hurt his ankle when coming to net at 5-2 in the first set. He called for a trainer but then continued playing.
"I would probably love to hit ... more points and to stay a little bit more time on the court," Djokovic said. "But on the other side we didn't get a lot of rallies today because of the conditions. I think everybody could see the power the wind was creating, and you couldn't really judge which side the wind is going to blow."
Djokovic, who won his fourth career title on clay at this month's Serbia Open, has reached the semifinals at the French Open the past two years. He also won the 2008 Australian Open.
"I talked to [Lapentti], and he says there is no use in playing if you can't move," said Djokovic, who himself retired in the quarterfinals of this year's Australian Open.
Fifth-seeded Juan Martin del Potro of Argentina had little trouble in his opening match at Roland Garros, beating Michael Llodra of France 6-3, 6-3, 6-1. Del Potro won four straight ATP titles last year, the first two on clay.
On Friday, Schuettler lost to Robin Soderling 6-0, 6-0 at the ATP World Team Championship in Germany.
"A double bagel is fine," said Schuettler, who reached the semifinals at last year's Wimbledon. "I had one last week. It's nothing new."
Gicquel was unapologetic about the thrashing.
"I didn't come here to sympathize," said the Frenchman, who was trying to win the third set at love as well. "If I tried to give him one or two games, then everything could be overturned against me."
Ninth seed Jo-Wilfried Tsonga, the 2008 Australian Open runner-up, registered his first win at his home Grand Slam with a 6-4, 3-6, 6-3, 6-4 victory over fellow Frenchman Julien Benneteau. No. 11 Gael Monfils of France also advanced, easily beating Bobby Reynolds of the United States 6-2, 6-3, 6-1 despite being hampered by a knee injury. Former French Open champion Juan Carlos Ferrero also advanced.
Tsonga celebrated his first win at the French Open by wearing a tie to his postmatch news conference.
"This is my first victory here. I celebrate this victory like this," a beaming Tsonga told reporters while showing off his navy blue tie. "I wanted to come in a tuxedo ... but my sponsor didn't really want me to. Now I've found a solution."
Asked if he would wear a bow tie if he ended up winning the tournament, Tsonga responded: "If I win, I will wear whatever you want but not a G-string."
Tsonga, who lost in straight sets to Andy Roddick in his only appearance at Roland Garros in 2005, prevailed after 2 hours, 43 minutes and will next face Argentine Juan Monaco, who breezed past Cyprus' Marcos Baghdatis 6-3, 6-2, 6-4.
Tsonga's compatriot Fabrice Santoro, playing a record 67th Grand Slam and his 20th French Open, was on the verge of being beaten by Belgian Christophe Rochus when he was handed a last-gasp respite. His match was halted by dusk while he was trailing 6-3, 6-1, 3-6, 5-3.
Dubbed the Magician for his habit of mystifying his opponents, the 36-year-old did not seem to have enough tricks up his sleeve to perform a great escape and prolong his Paris farewell tour. That was until the sun setting over Roland Garros came to his rescue.
The Parisian, who almost pulled out of the tournament because of a left knee problem, said he was not too troubled by the injury.
"I got into the match easily, better than I thought," he said. "At the very end, there was a warning sign, a little pain in the knee, but I think it's due to the fact it was a bit warmer, than cooler.
"I was quite reassured. I was moving around. I could hit the balls very strongly," he said.
Monfils, who reached the last four in Paris in 2008, will be up next against Romanian qualifier Victor Crivoi.
Like Santoro, Arnaud Clement will have to wait until Wednesday to discover whether he will make it into the second round.
