Alja Tomljanivoc stunned fifth seed Garbine Muguruza on Saturday 6-3, 1-6, 6-3, knocking the Spaniard out in the second round of the Indian Wells Masters.
The unfancied winner accounted for last week’s champion in a WTA Chacago run-up event.
The 47th-ranked Tomljanovic took little notice of her opponent’s ninth career title as she dispatched the double Grand Slam champion in just under two hours at the luxury Californian desert venue, breaking six times.
Muguruza came to the court with wins in three of four previous matches in the series, but was unable to move into the third round as Tomljanivoc earned her fourth career win over a Top 10 player.
The Australian will next face Tamara Zidansek as the Roland Garros semi-finalist beat Croat Ana Konjuh 6-4, 5-7, 6-3.
