Juan Martin del Potro: US Open 2009 win, Davis Cup and Olympic heroics rank among greatest career moments
Juan Martin del Potro looks as though he could soon retire from tennis. The former world No 3 and 2009 US Open champion has had an injury-ravaged career and only returned from a two-and-a-half year absence at the Argentina Open this week. It was an emotional occasion for Del Potro, who couldn’t hold back tears in the closing stages of his match against Federico Delbonis and was watched courtside by his mother for the first time in his career.
