By reaching her 10th WTA quarterfinal at the age of 17, Coco Gauff has matched Serena Williams' extraordinary career start

On Thursday Coco Gauff played her 10th quarterfinal on the WTA tour, continuing her remarkable start to her career. Aged just 17, Gauff has matched the early-career exploits of Serena Williams - who had also featured in 10 quarterfinals at that age.

Coco Gauff battled past Marta Kostyuk in the pre-quarterfinals of the Adelaide International 2 on Wednesday. The American converted four out of her five break points, eventually winning 6-3, 5-7, 6-3 to advance.

Gauff had a relatively easier time in the quarterfinals on Thursday, cruising past Ana Konjuh 6-3, 6-4.

Interestingly, none of the current top 10 WTA players managed to play anything close to 10 quarterfinals before entering their 20s. The two youngest top 10 players to have achieved the milestone are Aryna Sabalenka and Garbine Muguruza, both of whom played their 10th quarterfinal on the WTA tour at the age of 20.
