PARIS (Reuters) -World number three Stefanos Tsitsipas retired injured from his second-round match against Australian Alexei Popyrin with what appeared to be a right arm problem on a bad day for seeds at the Paris Masters on Wednesday.

The 23-year-old Greek was trailing 4-2 during the first set when he called the trainer on court before shaking hands with his opponent to signal his retirement.
