Fourth seed Elina Svitolina of Ukraine joined them, advancing past seventh-seeded Petra Kvitova of the Czech Republic 6-7 (4), 7-5, 6-2.
Svitolina needed two hours, 37 minutes to win the match, saving 13 of 16 break points (81.3 percent).
The No. 5 seed Aryna Sabalenka of Belarus will meet Halep after winning a three-set marathon in two hours, 28 minutes, 7-5, 4-6, 6-1 over Estonia’s Anett Kontaveit.
