Del Potro battles knee injury as Tsonga survives scare
Juan Martin Del Potro survived an injury scare as he battled his way into the second round of the French Open with a hard-fought victory over Albert Montanes at Roland Garros.
The Argentine, who received treatment for a knee problem, was forced to dig deep to claim a 6-2 7-6(5) 6-2 6-1 victory after more than three hours on Court Philippe Chatrier.
Seeded ninth in Paris, Del Potro started brightly as he grabbed an early lead before a backhand winner saw him break once more before coolly serving out for the opening set.
He looked to be firmly on course for victory when he opened up a 4-2 lead in the second set, but Montanes fought back to take the second set tiebreak.
The 2009 US Open champion appeared to be in some trouble as he received treatment on his left knee, but Del Potro recovered to set up a second-round clash with Frenchman Edouard Roger-Vasselin, who got the better of Vasek Pospisil 3-6 6-3 6-2 6-2.
Jo-Wilfried Tsonga shrugged off a sluggish start as he secured his progress with an ultimately routine victory over Andrey Kuznetsov. The Russian world No. 160 silenced the French crowds as he raced through the opening set, but Tsonga rallied to claim a 1-6 6-3 6-2 6-4 win on Court Philippe Chatrier.
Andy Roddick's woeful record at the French Open continued as he bowed out with defeat to local favourite Nicolas Mahut. Roddick, who has only once reached the fourth round at Roland Garros, was well beaten as he succumbed to a 6-3 6-3 4-6 6-2 reverse.
Mahut joins Spaniard Fernando Verdasco in the second round after the left-hander defeated Steve Darcis 6-3 6-2 7-6(4).
Last year's surprise quarter-finalist Fabio Fognini was the first man to book his place in the second round as he cruised past French wildcard Adrian Mannarino 6-0 7-5 6-1.
Former French Open champion Juan Carlos Ferrero met with little resistance as he cruised past world No. 157 Jonathan Dasnieres de Veigy 6-1 6-4 6-3. The Spaniard will meet Marin Cilic in the next round after the Croatian defeated Spanish qualifier Daniel Munoz De La Nava 6-4 6-4 7-5.
Stanislas Wawrinka avoided an upset as he hung on to defeat Flavio Cipolla 6-3 6-3 4-6 3-6 6-2 . Wawrinka appeared to be struggling as he threw away a two-set lead, but he dug deep to book his place in the second round.
