Top-seeded Aryna Sabalenka needed more than two hours to rally past unseeded Nikola Bartunkola on Friday and earn a spot in the Berlin Tennis Open semifinals.

Czechia’s Bartunkola, the No. 62 player in the world, claimed the first set but could go no further against the top-ranked Belarus native in a 2-6, 7-6 (2), 6-4 match that lasted two hours, 23 minutes. Bartunkola converted just six of 17 break-point chances while Sabalenka converted five of eight.

Sabalenka will face third-seeded Jessica Pegula in Saturday’s semifinal play. Pegula advanced with a hard-fought 7-6 (5), 7-6 (8) win over Madison Keys. While Keys owned a 10-5 advantage in aces, she converted only two of her seven break-point opportunities.

No. 8 Linda Noskova of Czechia moved on with a 6-1, 6-3 victory over Spain’s Paula Badosa. Noskova takes on unseeded Alexandra Eala in Saturday’s second semi as the Phillipines native followed up her upset of No. 2 Elena Rybakina with a 6-3, 6-4 win over No. 6 seed Elina Svitolina of Ukraine.
