Ons Jabeur cruised into the Madrid Open quarter-finals on Monday, spending just over an hour on court in a statement 6-0 6-4 win over ninth seed Jelena Ostapenko.

Jabeur, who won her first and so far only WTA 1000 title in Madrid in 2022 then missed last year's tournament through injury, made it nine wins in a row in the Spanish capital to book a last-eight meeting with either Coco Gauff or Madison Keys.

Eighth seed Jabeur only needed 68 minutes to see off the former French Open champion, not dropping a game in a 21-minute opener in which she won 88 per cent of first-serve points.

Ostapenko improved in the second set, breaking back immediately after losing serve in the opening game, but Jabeur got the crucial break to go 5-4 up before serving the contest out.

Data Debrief: Jabeur dominates on the clay

Jabeur's win sealed her third quarter-final appearance at a WTA 1000-level event on clay since 2020. Only world number one Iga Swiatek (four) has reached more during that span.

A dominant start did the trick for the Tunisian on Monday, as she became the first player to take an opening set 6-0 against a top-10 ranked player in Madrid since the 2021 final, when Aryna Sabalenka did so in her victory over Ashleigh Barty.
