Mboko

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

Muchova 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 Muchova 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, improved her record this season to 19-6 with her run to the quarterfinals in Miami.
