MIAMI GARDENS, United States — Alexandra Eala, the 19-year-old from the Philippines who upset Australian Open champion Madison Keys on Sunday (Monday Manila time), was handed a place in the quarterfinals of the Miami Open.

This after Eala's fourth-round opponent, Spain’s Paula Badosa, pulled out with a lower back injury on Tuesday.

In the last eight, Eala will face the winner of Tuesday's match between Ukraine's Elina Svitolina and second-seed Iga Swiatek.

The Filipina herself was also hindered by an injury on her thigh that forced her to call for a medical timeout in the first set of her match with Keys.

She bucked this injury, as Eala dug deep against the error-riddled Keys, pulling off a 6-4, 6-4 stunner over the World No. 5 to become the first Filipina in the Open era to defeat a former Grand Slam champion at the WTA level.

Ranked 140th in the world, Eala is also the first netter from the Philippines to defeat a top 10 player since 1990, according to the Miami Open website. 

In the first round, she defeated World No. 73 Katie Volynets, 6-3, 7-6(3), and followed it up with an upset victory over World No. 25 Jelena Ostapenko, 7-6(2), 7-5.
