Beatriz Haddad Maia has taken down the World No. 1…

The 26-year-old Brazilian tennis player defeated top-ranked Iga Swiatek of Poland 6-4, 3-6, 7-5 in windy conditions on Thursday to reach the National Bank Open quarterfinals.

Haddad Maia beat a top-ranked player for the first time to become the first Brazilian woman to advance to the quarterfinal of a WTA 1000 tournament.

A back-to-back champion on the grass in Nottingham and Birmingham, she came to Toronto at a career-high 24th in the world.

“I had a lot of tough moments in my career,” Haddad Maia said. “I have already had four surgeries and I’m only 26 years old. So when I have special moments I try to enjoy. ”

Swiatek had nine double faults to one for Haddad Maia.

“Right now it’s hard to say if it was more her game or the wind that really messed up my first set,” Swiatek said. “I think she just used the conditions better than me. When she was playing with the wind she was playing really strong balls and sometimes I was late for them.”

Haddad Maia will face Belinda Bencic of Switzerland in the quarterfinals. Bencic followed her victory over Serena Williams on Wednesday night by beating eighth-seeded Garbine Muguruza of Spain 6-1, 6-3 in the late match.
