Simona Halep avenged last year’s French Open loss to Amanda Anisimova by thrashing the American teenager 6-0, 6-1 on Friday to reach the last 16 at Roland Garros.

Top seed and title favourite Halep extended her career-best winning run to 17 matches and will meet another 19-year-old, Poland’s Iga Swiatek, for a place in the quarter-finals.

Polish teenager Swiatek dismissed former Wimbledon finalist Eugenie Bouchard 6-3, 6-2 to seal a return to the last 16, matching her best result at a Grand Slam.

Anisimova knocked Halep out in the last eight in Paris a year ago, but the two-time Grand Slam champion made only seven unforced errors as she secured a resounding victory in just 54 minutes.

Two-time quarter-finalist Elina Svitolina ensured she will stick around for the second week in Paris with a 6-4, 7-5 win over 27th seed Ekaterina Alexandrova.

In men’s section, last year’s finalists Rafael Nadal and Dominic Thiem charged into the last 16 while French wildcard Hugo Gaston, ranked at 239 in the world, defeated 2015 champion Stan Wawrinka in five sets.

Nadal, the three-time defending champion, secured a smooth 6-1, 6-4, 6-0 win over world number 74 Stefano Travaglia. The 12-time Roland Garros winner next faces American qualifier Sebastian Korda, ranked a lowly 213th, for a quarter-final spot.

France’s Gaston won the rain-interrupted tie 2-6, 6-3, 6-3, 4-6, 6-0 to become the second player ranked outside the top 200 to reach the last 16 on Friday

While Austrian third seed Thiem broke down early resistance from Norway’s Casper Ruud to secure an impressive 6-4, 6-3, 6-1 victory.
