Aryna Sabalenka begins US Open title defence with victory against Camila Osorio

• Reigning women’s singles champion wins 6-2, 6-4

• Men’s 10th seed Arthur Fils beaten by Stefanos Tsitsipas

Aryna Sabalenka said she is determined to look ahead, rather than dwell on a difficult past few months, after beginning her US Open title defence with a 6-2, 6-4 win against Camila Osorio.

“The good thing for me is not looking back no matter what, if it’s good or bad, because I feel a good result can also stop you from performing well because you’re basically focusing on the past,” Sabalenka said. “I never look back. If I win the tournament or lose the tournament, today is a new day, and I have to stay in the moment.”
