Naomi Osaka wins second US Open title after comeback win over Victoria Azarenka. Open title in three years with a 1-6 6-3 6-3 comeback win on Saturday which cemented her status as the sports leading light both on and off the court. Unlike the 22-year-old Japanese's first U.S. Open victory in 2018 over Serena Williams, performed in an amazing Arthur Ashe Stadium, Saturday's drama unfolded in an unusually quiet arena. COVID-19 health and safety protocols prevented fans from entering the Billie Jean King National Tennis Center.
