Eight-time champion Rafael Nadal stretched his French Open winning streak to 31 matches, equalling his longest run at the tournament, with a 6-2, 7-5, 6-2 victory over 65th-ranked Leonardo Mayer of Argentina in the third round on Saturday.

The last time Nadal won 31 in a row at Roland Garros, he failed to make it 32, losing in the fourth round in 2009 to Robin Soderling.

That remains the Spaniard's only defeat in 63 matches at the tournament.

Nadal has reached the fourth round all 10 times he has entered the French Open. Roger Federer, who won his third-round match Friday, is the only other man to make it to the final 16 in Paris that many times in a row. The top-seeded Nadal made only 10 unforced errors against Mayer.

Toronto's Nestor, Zimonjic reach doubles quarters

Canadian Daniel Nestor and Serbian partner Nenad Zimonjic reached the quarter-finals of the French Open on Saturday with a 6-4, 7-5 defeat of 13th seeds Jean-Julien Rojer of the Netherlands and Romania's Horia Tecau.

The victory in just under 90 minutes puts the veteran third seeds up against the winner from Austrian Jurgen Melzer and Spain's Feliciano Lopez versus Croatia's Marin Draganja and Florin Mergea of Romania.

Tecau proved to be the weak link, with the Romanian losing serve once per set as Nestor and Zimonjic won their 11th consecutive match on clay.

The pair came to Paris with trophies in Madrid and Rome; Nestor has won the French doubles title four times since 2007.

Tecau was broken in the ninth game of the first set and in the penultimate game of the second, with the 41-year-old Nestor from Toronto serving out the win and Zimonjic clinching victory with a poached cross-court winner.

Nadal will face 83rd-ranked Dusan Lajovic of Serbia, who got past Jack Sock of the United States 6-4, 7-5, 6-3.

The man Nadal beat in last year's final, fifth-seeded David Ferrer, got to the fourth round by defeating No. 32 Andreas Seppi of Italy 6-2, 7-6 (2), 6-3.

Ferrer improved to 7-0 against Seppi, winning all 15 sets they've played. Ferrer, who has lost a total of 26 games through three matches this year in Paris, will face No. 19 Kevin Anderson of South Africa for a place in the quarter-finals.

Murray, Kohlschreiber to continue cliffhanger Sunday

Anderson advanced when Ivo Karlovic retired after one set Saturday because of a bad back.

The third-round French Open match between Wimbledon champion Andy Murray and 28th-seeded Philipp Kohlschreiber was suspended at 7-all in the fifth set because of fading light.

There are no artificial lights at the clay-court Grand Slam tournament. The match will resume Sunday, with No. 7 Murray serving.

Murray — who got both upper legs massaged by a trainer during fifth-set changeovers — twice was two points from victory while leading 6-5 as Kohlschreiber served, but couldn't get closer.

Kohlschreiber then held a break point at 6-all that Murray erased with a backhand winner.

Kohlschreiber won the first set 6-3. Murray took the next two 6-3, 6-3, and Kohlschreiber took the fourth 6-4.

The match between Richard Gasquet and Fernando Verdasco was suspended with Verdasco leading 6-3, 6-2, 2-2.

Halep, highest seed left, avoids upset curse

In a women's draw marked by upsets, No. 15 American Sloane Stephens will take on No. 4 Simona Halep of Romania. Neither has ever made it to the quarter-finals in Paris.

Stephens eliminated No. 22 Ekaterina Makarova of Russia 6-3, 6-4 Saturday, while Halep beat 55th-ranked Maria-Teresa Torro-Flor of Spain 6-3, 6-0 as the temperature approached 70 degrees (20 Celsius) on the sunniest afternoon of Week 1 at the clay-court major after several days of overcast skies and occasional rain.

At No. 4, Halep is the highest seeded woman left at Roland Garros, because of early losses by No. 1 Serena Williams, No. 2 Li Na and No. 3 Agnieszka Radwanska.

"That's a surprise for everyone," said Halep, the runner-up on clay at Madrid three weeks ago. "Is not easy to be the [top] seeded now, during the tournament. But I try just to keep ... the pressure (away)."

In other action Saturday, 2009 French Open champion Svetlana Kuznetsova came back to beat an error-prone fifth-seeded Petra Kvitova 6-7 (3), 6-1, 9-7, while the 2008 title winner at Roland Garros, Ana Ivanovic, bowed out with a 6-3, 6-3 loss to 23rd-seeded Lucie Safarova of the Czech Republic.

The 27th-seeded Kuznetsova, who also won the 2004 U.S. Open, broke at love in the final game when a 13-stroke exchange was capped by a missed forehand by Kvitova, her 65th unforced error on a day the 2011 Wimbledon champion repeatedly sought treatment from a trainer and had a bandage on her upper right leg. Kuznetsova, meanwhile, made only 20 unforced errors in the 3-hour, 13-minute match and faces Safarova next.

Tenth-seeded Sara Errani, the 2012 French Open runner-up to Maria Sharapova, made only seven unforced errors in her 6-0, 6-1 victory over 98th-ranked Julia Glushko of Israel. Errani now plays 2008 U.S. Open runner-up Jelena Jankovic, a 6-1, 6-2 winner against No. 26 Sorana Cirstea of Romania.

Halep, a Romanian, was the girls' champion at Roland Garros in 2008, but she had never been past the second round of the French Open's main draw until this year.

"I hope," she said with a smile, "[it won't] be the first and the last."
