Mboko eliminated again in quarterfinals of WTA 1000 tournament, losing to Czechia's Muchová

Canada's Victoria Mboko was ousted by Czechia's Karolina Muchová deep into a WTA 1000 tournament for a second time this year.

Muchová posted a 7-5, 7-6 (5) win over Mboko in a tightly contested quarterfinal Tuesday at the Miami Open.

The Czech veteran scored the only break of the match when she came back from 30-love to take a 6-5 lead in the first set.

She then saved a set point in the second set before winning the tiebreaker, converting match point against serve.

Mboko was in the quarterfinals of a third straight 1000-level tournament, a run that started with a loss to Muchová in the final of the Qatar TotalEnergies Open last month.

She also advanced to the quarterfinals at Indian Wells, Calif., earlier this month before losing to top-ranked Aryna Sabalenka.

The 19-year-old from Burlington, Ont., who entered Miami ranked ninth in the world, has a season record of 19-6 following her run to the quarterfinals in Miami.

In women's doubles, Ottawa's Gabriela Dabrowski and Luisa Stefani of Brazil took down Sofia Kenin of the United States and Russia's Liudmila Samsonva 7-6, 6-4 in quarterfinal play.
