Marta Kostyuk was beaten by Donna Vekic 6-4, 2-6, 7-6 (8) in a nerve-racking quarterfinal match on Wednesday. After losing the opening set, Kostyuk upped her game and dominated the second set. She did not buckle under the pressure heading into a crucial third set. Kostyuk was seen grooving to Bruno Mars’ popular song ‘Uptown Funk’ played in the stadium.
