At age 39, Novak Djokovic can still wear opponents down.
Even opponents nearly half his age – and in front of a hostile crowd.
Djokovic came back from a set down for a 5-7, 7-5, 6-1, 6-4 victory over 22-year-old home player Giovanni Mpetshi Perricard in the first round of the French Open on Sunday in his record 82nd Grand Slam appearance.
