Dual Wimbledon champion Petra Kvitova has crashed out of the Brisbane International, falling to Estonia’s Anett Kontaveit in the second round.
The fourth seed was ousted 7-5 7-6 (7-1) by the world No.20 Kontaveit.
World No.7 and 2011 Brisbane champion Kvitova did it tough as she tried to back up from her marathon three hour first round win over American Danielle Collins barely 24 hours earlier.
Kontaveit booked a quarter-final clash with Ukraine’s Lesia Tsurenko.
Earlier, eighth seed Anastasija Sevastova cruised into the quarter-finals with a second round thrashing of British qualifier Harriet Dart.
Latvia’s Sevastova booked a last-eight clash with second seed and reigning US Open champion Naomi Osaka of Japan with the 6-2 6-0 rout.
World No.11 Sevastova – a 2018 US Open semi-finalist – had no troubled backing up after knocking out Australia’s Daria Gavrilova in straight sets in the first round.
