Naomi Osaka came from behind to beat Victoria Azarenka to clinch second US Open title

Naomi Osaka battled back from a set down against Victoria Azarenka to lift her second US Open title in three years with a 1-6 6-3 6-3 victory.

The 22-year-old Japanese star, already the highest-earning female athlete in the world, adds another £2.3million in prize money to her fortune while she becomes the first Asian player to win three major titles, surpassing Chinese trailblazer Li Na.

Osaka walked onto the court wearing a mask with the name of Tamir Rice, a 12-year-old black boy who was killed by police in Cleveland in 2014.
