Wawrinka out of Olympics

World No. 4 Stan Wawrinka yesterday announced his withdrawal from the Rio Olympics because of a back injury, dealing another body blow to the tennis tournament.

The 31-year-old is the third Swiss player to withdraw after Roger Federer and Belinda Bencic.

"I am very sad," said Wawrinka, the former French and Australian Open champion. "Going to Rio was close to my heart. After Beijing (2008) and London (2012), I wanted to live these Games in Brazil. Sadly, it's not possible."

Wawrinka aggravated his back injury in Toronto last week where he reached the semi-finals. - AFP.
