Former U. S. Open winner Stan Wawrinka hinted that he was getting closer to hanging up his racket after being forced to retire mid-match during his opening round contest at the hardcourt major on Monday against French lucky loser Corentin Moutet.
Wawrinka, 37, had twice called the trainer on court to tend to his finger and was trailing 6-4 7-6(7) when he signalled he could no longer continue against Moutet, who managed to make the main draw despite losing in the qualifying stage.
