Coco Gauff's unprecedented run in the Australian Open comes to an end on Sunday, courtesy of another American player. The 15-year-old Gauff lost to 21-year-old Sofia Kenin who reached her first major quarterfinal with the victory. "I just needed to calm down, relax, try my best and fight," the 14th-seeded Kenin said. "I'm just so speechless."
In her previous match, the 67th-ranked Gauff beat Naomi Osaka to become the youngest player in the professional era to defeat the reigning women's champion at the Australian Open. But Gauff did not play as well this time, winding up with 48 unforced errors, more than twice as many as Kenin's 22.
