Rafael Nadal returned to singles action with a 6-3, 6-4 victory on clay over Leo Borg, the 21-year-old son of Swedish great Bjorn Borg, in the first round of the Nordea Open in Bastad on Tuesday. “For me it has been a huge honor to play against the son of one of the biggest legends in the history of our sport,” Nadal said about his 21-year-old opponent. Nadal won the singles title in southern Sweden as a 19-year-old in 2005 and this week is his first time back since then as he prepares for the Olympic tournament on clay at Roland Garros in Paris.
