WTA roundup: Emma Raducanu rallies in Hobart

Completing a first-round match that lasted two days, No. 1 seed Emma Raducanu earned a 6-3, 7-6 (2) victory against Colombian Camila Osorio on Wednesday at the Hobart International in Australia.

Osorio was leading 4-2 in the second set Tuesday when rain ended play. After Britain's Raducanu earned the win, the 2021 U.S. Open champ earned passage to the quarterfinals after Poland's Magdalena Frech withdrew due to a left thigh injury.

In second-round action, No. 3 seed Iva Jovic defeated Mexico's Renata Zarazua 6-1, 6-2; Italy's Elisabetta Cocciaretto knocked out No. 4 Ann Li 1-6, 7-5, 7-5; and Hungary's Anna Bondar ousted No. 6 Tatjana Maria of Germany 7-6 (7), 7-5. Also reaching the quarterfinals were Croatia's Antonia Ruzic, Serbia's Olga Danilovic and Australia's Taylah Preston, who will face Raducanu.
