American knocks out 10th seed 6-3, 6-4 in first roundSabalenka, Swiatek, Kenin and Muguruza all throughWhen Sloane Stephens won the
US Open in 2017 it seemed as if she would go on to establish herself as a serial champion, someone with the ability to rack up numerous grand slam titles. Four years on, and after a slump in form and some difficult times in her personal life, the
American showed her talent is undimmed with a 6-3, 6-4 victory over the two-times former champion Petra Kvitova in the first round.
Returning aggressively and maintaining her focus when down four break points in the second set, Stephens held on to clinch what was only her second win over a Top 10 opponent in three years.
