Karolina Pliskova has stunned her home tennis fans after blowing a lead and losing to Russian qualifier Veronika Kudermetova at the Ostrava Open.
Kudermetova pulled off a shock victory over the Czech World No.6 on Thursday to reach the quarter-finals of the WTA event in Prague.
‘TIME TO SAY GOODBYE’: Tennis star's sudden retirement at 31
Pliskova, a former World No.1 and the tournament's second seed, looked in complete control after taking the opening set.
Kudermetova took a medical timeout for a rib problem and looked set for a straight-sets loss.
However, the hometown hero was soon pushed on to the back foot as Kudermetova rallied to level the match, before progressing 4-6 6-4 6-3 in just under two hours.
Fans couldn’t believe what they were seeing, flocking to social media in shock.
I'm still in shock that Iga steamrolled to a slam in age 19 and so many girls like Pliskova, Svitolina etc are all the time in the "pretenders" category and they lack something to win...

Pliskova is a complete meltdown, a set and a break up and now getting hammered, how on earth is she ranked 6 in the world, she's never won a slam nor will she ever, mentally very weak

Alex de Minaur looking good in Antwerp
Meanwhile, Alex de Minaur's draw at the ATP Tour's Antwerp Open has opened up after qualifier Marcos Giron stunned top seed David Goffin in the second round.
Australian De Minaur, the eighth seed, will face world No.94 Giron in the quarter-finals after the American defeated Belgian Goffin 6-3 7-5 in one hour and 41 minutes on Thursday.
The 27-year-old Giron, who underwent right hip surgery in December 2015 and left hip surgery in February 2016, saved 10 of the 13 break points against world No.14 Goffin on his way to claiming his first top 20 scalp.
Giron's previous-best win came last year at Indian Wells against then world No.24 de Minaur.
Fifth-seeded Canadian Milos Raonic beat Briton Cameron Norrie 7-5 7-6 (7-4) to advance to a last-eight meeting with Bulgarian fifth seed Grigor Dimitrov.
