Germany's Zverev withdraws from Olympics

Alexander Zverev has become the latest tennis player to drop out of the Rio Olympics, citing health issues.

The rising German talent, who is ranked No. 25 in the world, said in a statement that he did not feel "100 percent" in his last two matches in Washington and Toronto.

After consulting with his doctors and his team, Zverev said: "we have decided that I have to withdraw from the Olympics."

He did not give details.

The 19-year-old beat Roger Federer in the Halle Open semi-finals in June but lost in the semifinals of Washington to Gael Monfils and to Lu Yen-hsun in the first round of the Masters Series event in Toronto.
