PARIS — Jelena Jankovic easily advanced to the second round of the French Open on Tuesday by beating Stephanie Foretz of France 6-2, 6-2.

The fourth-seeded Serb, who won two clay-court warmups heading into the tournament at Roland Garros, converted four of her five break points in the first set, and then broke her unseeded opponent three more times in the second.

Jankovic, who is ranked fifth, won the Italian Open earlier this month, making her one of the favorites.

In men's play, No. 13 Mikhail Youzhny advanced when Jan Hernych of the Czech Republic pulled out after only nine points in the first game of the match because of a back injury.

"I really wanted to play today, actually. But I have a little pain in my back, so one more day rest is good," said Youzhny, who has reached three finals this year. "After Hamburg, I only practiced, so I think one more day for my back is good."

Later today, Roger Federer was to complete his match against Michael Russell. The top-ranked Swiss star, who needs to win the French Open to complete a career Grand Slam, was leading the American 6-4, 4-1 before rain halted play Monday.

Two-time defending champion Rafael Nada was scheduled to play Juan Martin del Potro of Argentina in the late match on center court.

On the women's side, No. 6 Nicole Vaidisova of the Czech Republic was playing Emmanuelle Gagliardi of Switzerland.

Maria Sharapova and Amelie Mauresmo will play no earlier than Wednesday.

The first two days of the tournament were marked by rain. Only 14 matches were completed before today.

Venus Williams, a five-time major champion who had not won a Grand Slam match in 11 months, reached the second round Monday by beating French teenager Alize Cornet 6-4, 6-3 on a damp court after a three-hour delay at the start of the day.

"I was already fortunate to be first on," said Williams, one of six women to advance as three rain delays at Roland Garros forced organizers to postpone or suspend 58 matches.

Fourth-seeded Nikolay Davydenko was the only man to reach the second round on Day 2. The U.S. Open semifinalist easily beat Stefano Galvani of Italy 6-3, 6-1, 6-1 as the rain returned and eventually halted play.
