Dayana Yastremska had not won a tennis match since playing Simona Halep of Romania in two tight sets in Rome last fall. An exonerated Yastremska made a triumphant return to action at the inaugural Hamburg European Open on July 8 after she defeated Magdalena Frech of Poland 7-6(5), 6-1 in her first match since she was cleared of an anti-doping rule violation charge in June of this year.
