Coco Gauff is through to the semi-finals of the French Open after a 6-7 (6-8) 6-4 6-1 victory over compatriot Madison Keys at Roland-Garros on Wednesday.

But the 21-year-old had to overcome a poor start to get the win, having trailed 4-1 in the first set and been one point away from 5-1.

After saving that point, Gauff battled back to get within a point of taking the first set, though three double-faults in the tiebreaker put paid to her chances.

The second set was better, although Gauff was pegged back from 4-1 up to 4-4 by Keys. But a break and a hold from Gauff later, the match was level.

Gauff then motored through the decider, breaking in the first game and again in the fifth to make it 4-1.

Having held to make it 5-1, Gauff then found herself with match points in hand and was eventually able to rubber-stamp the victory.

25 - Coco Gauff (21y 73d) is the youngest American in the Open Era to claim 25+ career Women's Singles match wins at Roland Garros, and the youngest overall Martina Hingis (19 years and 241 days) in 2000. Wow.#RolandGarros | @rolandgarros @WTA @WTA_insider pic.twitter.com/cKZOCceas9

Data debrief: Scruffy Gauff gets through

The match itself was a scruffy one, with a combined 101 unforced errors and 14 breaks of serve, while Gauff herself registered 10 double-faults.

Gauff's first set was the first that she has dropped while at the tournament.

But she is now the youngest American in the Open Era to win 25 or more women's singles matches at Roland-Garros.

Gauff is also the youngest player since Serena Williams in 2002 to claim a 10th women's singles win against a former grand slam champion.
