Hsieh Su-Wei soared in the scorching heat to shock No.3 seed Garbine Muguruza 7-6(1) 6-4 at Rod Laver Arena on Thursday.
“I've been on tour too long, so there must be a few interesting matches in my life,” stated the elated Chinese Taipei player.
“Of course this is one of the biggest players I beat. So, it's of course a great memory for me.”
The world No.88 previously only had one top-20 victory to her name (Johanna Konta, French Open 2017), but the 32-year-old counter-punched with aplomb to disguise her shots and quell the Wimbledon champion’s firepower.
Hsieh, a fourth round participant at Melbourne Park back in 2008, settled in following an exchange of breaks. At the fourth attempt Hsieh redirected a piercing forehand down the line to post a 3-1 lead.
However, from 2-5 the world No.3 was able to find some rhythm and two holds to love enabled the Spaniard to earn a tiebreak.
