Cori "Coco" Gauff beat Polona Hercog in three sets on Friday to advance to the fourth round at Wimbledon, setting up a showdown with No. 7 Simona Halep in the round of 16.
The 15-year-old American became the youngest player to qualify for Wimbledon in the Open era last week, but on Friday she showed poise well beyond her years as she came back to beat the world No. 60 on Centre Court at the All England Club.
Hercog won the first set 6–3 and appeared to be on her way to victory after Gauff dropped her serve early in the second set.
