PARIS – American Sloane Stephens rolled to a 6-4, 6-3 win on Sunday over Spain’s Garbiñe Muguruza in the fourth round at the French Open.
Stephens, the finalist last year, needed one hour and 40 minutes to beat Muguruza, who won the title at Roland Garros in 2016.
The world No. 7, who won the US Open in 2017 and made the semifinals in Madrid this season, was too much for Muguruza, who had played brilliantly until Sunday.
Muguruza got an early break, but Stephens got the break back in the sixth game of the first set.
The Spanish star struggled on serve from that point on, allowing the American to take the first set 6-4.
The 26-year-old Stephens, playing in her sixth round of 16 in Paris, lost to Romania’s Simona Halep in the 2018 final.
The American was the last big-name player standing in the way of Muguruza, who had watched as several potential rivals lost.
Stephens’s rival for a spot in the semifinals will be Britain’s Johanna Konta, the No. 26 seed, who defeated Croatia’s Donna Vekic 6-2, 6-4 to advance to her first quarterfinals at Roland Garros.
Konta, the first British player to reach the quarters in Paris since 1983, is looking to advance to her third Grand Slam semifinals after making the final four at the Australian Open in 2016 and Wimbledon in 2017.
In other action, Croatia’s Petra Matic, who beat Estonia’s Kaia Kanepi 5-7, 6-2, 6-4, will play 19-year-old Czech surprise Marketa Vondrousova, who beat Latvia’s Anastasija Sevastova 6-2, 6-0 in the quarterfinals.
