American Claire Liu won her first-ever match over a Top 10 player, defeating top seed and home favorite Ons Jabeur 6-4, 4-6, 6-4 at the Jasmin Open Monastir in Tunisia on Friday.

Jabeur can hang the loss on her service game. She didn’t hit any aces, struck seven double faults, had just a 52 percent first-serve percentage and was broken six times in seven chances by Liu.

The win sends Liu to the semifinal round, where she’ll face Elise Mertens of Belgium, the fifth seed. The other semifinal will feature No. 2 seed Veronika Kudermetova of Russia and No. 3 seed Alize Cornet of France.

Mertens eliminated Japan’s Moyuka Uchijima 6-0, 3-6, 6-4. Kudermetova dropped Diane Parry of France 6-4, 6-1, and Cornet defeated Slovenia’s Tamara Zidansek 7-5, 7-6 (7).
