Paris - Juan Martin del Potro made a triumphant return to the French Open on Tuesday, defeating compatriot Guido Pella in his first match at Roland Garros since 2012.
The injury-plagued Argentine, who sat out this year's Australian Open over fitness concerns, blitzed Pella 6-2, 6-1, 6-4 to reach the second round.
Del Potro, seeded 29th, will face Nicolas Almagro or Marcos Baghdatis next and is a potential third-round opponent for world number one Andy Murray.
His best result in Paris came in 2009 when he lost to eventual champion Roger Federer in the semi-finals, the same year Del Potro beat the Swiss to lift the US Open title.
