Coco Gauff has added another historic accolade to her decorated resume. Gauff earned her latest achievement on Sunday when she won the China Open final with a 6-1 6-3 sweep against Czech star Karolina Muchová. The 20-year-old tennis star, who now owns eight WTA titles, became the first American to win the China Open since Serena Williams took the title in 2013, CNN reported. Gauff has now won her first seven hard-court finals, making her the first woman to achieve such a feat in the Open era. Photo by Lintao Zhang/Getty Images
