Novak Djokovic took his winning streak to 41 matches and set up a blockbuster French Open third-round clash with giant Argentine dangerman Juan Martin del Potro on Wednesday.
Second seed Djokovic, who is tipped to relieve five-time champion Rafael Nadal of his Roland Garros title and top ranking, was leading Victor Hanescu 6-4, 6-1, 2-3 when the Romanian quit their second-round tie with a leg injury.
“It's never easy to see an opponent giving up. It's bad luck for him. I played well and it's good to spend as little time on court as possible," said Djokovic.
The Australian Open champion, who has also won all four Masters titles in 2011, now stands five wins away from equalling Guillermo Vilas's record for a winning streak.
He is also only three away from John McEnroe's 1984 record for an undefeated start to a season.Argentine 25th seed Del Potro, the former US Open champion and a 2009 semi-finalist in Paris, made the last 32 with a 6-3, 6-2, 6-4 win over Slovenia's Blaz Kavcic.
Del Potro missed last year's Roland Garros to recover from wrist surgery and was almost forced out of this edition because of a hip injury.
The former world number four's ranking slipped to 485 during his time off tour, but he has been in fine form in 2011, winning tournaments at Delray Beach and Estoril."It should be a beautiful match with Novak. It'll be a special occasion against a great player. He's the favourite, but I will try and fight for the victory," said the Argentine.
Roger Federer, for one, was looking forward to the Djokovic-Del Potro clash, even if the Serb has won all of their three previous meetings without dropping a set.
Federer has it easy
Third-seeded Federer won 13 games in succession as the 16-time Grand Slam title-winner easily disposed of French wild card Maxime Teixeira 6-3, 6-0, 6-2 in his second-round tie.
The 2009 champion will next face Serbian 29th seed Janko Tipsarevic, who beat Spain's Pere Riba.
The Swiss great overcame an early break before breezing through in just 84 minutes, leaving Teixeira, playing in his first Grand Slam event, looking every inch the world 181.
"He fought really hard and was trying his best," said Federer.
"It was a good match. I'm happy with the way I played. I feel like I am in the tournament now."
Next up is Tipsarevic, the colourful Serb who stretched Federer to five sets in the 2008 Australian Open third round.
"He's a dangerous player, especially on the big courts against the big players," said the 2008 French Open champion.
Paes, Bhupathi advance in mixed
India’s doubles star Mahesh Bhupathi and Leander Paes advanced to the second round in the mixed doubles event with contrasting victories.
Fifth seed Bhupathi and Zheng Jie of China got the better of Petra Kvitova of Czech Republic and Sergiy Stakhovsky of Ukraine 6-7 (3), 6-0, 10-8 while Paes and his Czech partner Iveta Benesova, seeded seventh, thrashed Aravane Rezai and Grigor Dimitrov 6-3, 6-1.
