Johanna Konta proved that she had found her comfort zone on Roland Garros’ red clay as she surged to a 6-2 6-4 win over Donna Vekic on Sunday in Paris.
The victory helped her to become the first British woman to reach the quarter-finals of the French Open in 36 years.
Konta, before this year had never won a match at the claycourt major in four previous appearances.
She struck 33 winners, including seven aces, to dispatch the 23rd-seeded Croatian on the hottest day of the tournament so far.
Temperatures were set to rise to as high as 31 degrees Celsius.
The last British woman to reach the Paris quarter-finals was Jo Durie in 1983, and she eventually lost in the semi-finals.
Although Konta and Vekic had split their previous six encounters, this was their first meeting on clay.
The previous encounters had included an epic clash in the second round of Wimbledon in 2017 that lasted more than three hours.
After three straight breaks of serve, Konta was the first to hold, going up 3-1.
With Vekic struggling to land a first serve in, Konta went up a double break for 5-2.
Serving for the first set, the Briton saved four break points before taking it with her third ace.
After swapping breaks early in the second set, a drop shot handed Konta another break, and she held serve to love clinch the match in 84 minutes.
Konta will play either 2017 U.S. Open winner Sloane Stephens or twice Grand Slam champion Garbine Muguruza for a spot in the semi-finals.
