Poland’s Magdalena Frech rallied to upset No. 6 seed Mirra Andreeva of Russia 2-6, 7-5, 6-0 in first-round action at the Berlin Tennis Open on Monday.

Andreeva, who turned 18 in April, has had a successful season. She won WTA 1000 titles in Dubai and Indian Wells and became the youngest WTA 1000-level champion in tour history. But Frech caught her by surprise Monday; the 27-year-old held on in the second set after squandering a 4-1 lead before dominating the third set.

No. 8 seed Paula Badosa of Spain breezed past Germany’s Eva Lys 6-1, 6-3 in 60 minutes, while Emma Navarro beat Ukraine’s Marta Kostyuk 6-2, 6-3. Navarro and Badosa will meet in the second round in a matchup of the Nos. 9 and 10 players in the WTA rankings.

Also advancing were Ons Jabeur of Tunisia, Rebeka Masarova of Switzerland and Katerina Siniakova of the Czech Republic.
