Unseeded Danish teen Clara Tauson upset No. 3 seed and defending champion Jelena Ostapenko 6-3, 4-6, 6-4 to win the BGL BNP Paribas Luxembourg Open on Sunday.
The 18-year-old Tauson claimed her second title, having won in Lyon as a qualifier in March in just her second Tour-level main draw appearance. She also defeated U.S. Open champion Emma Raducanu in the Chicago WTA 125 final last month.
