• Belarussian keeps composure to beat American 7-5, 7-5
• World No 2 has won two grand slam titles this year

As Aryna Sabalenka has cemented herself at the top of her sport over the past two seasons, in so many of the biggest grand slam matches her greatest opponent has been herself. Even when she has come in radiating with confidence, her game in full bloom, her head so often gets in the way. Recovering from so many painful collapses has required resilience beyond measure.

Nowhere have these struggles been more evident than in New York, a city that perfectly suits her electrifying game and outsized personality but where the positives from her two semi-finals and a final in the past three years had been blunted by brutal losses.
