Ons Jabeur moved into the Roland Garros quarter-finals for the first time on Monday, defeating Bernarda Pera 6-3, 6-1 in the fourth round.
Last year’s grand Slam finalist at Wimbledon and the US Open started plugging the hole in her French Open resume with victory in 63 minutes.
The Tunisian polished her career record against American opponents as she won her 34th against 16 losses in that category.
Seventh seed Jabeur was kept under pressure by the 36th-ranked Pera, saving eight of a dozen break points; she broke the American eight times.
Pera was playing the first round of a Grand Slam for the first time while Jabeur has now reached at least the quarters at all four of the majors.
