Alexandra Eala, a 19-year-old wildcard from the Philippines, produced a huge upset at the Miami Open on Wednesday, beating World No. 2 Iga Swiatek 6-2,7-5 to enter the semi-finals. 

Ranked 140th in the world, Eala, the first woman from her country to reach the last eight of a WTA 1000 tournament, took advantage of an unusually poor display from Swiatek.
