Earlier, 21-year-old Kyrgios had beaten Pavlasek 7-5 6-4 in the singles, meaning the pressure was on his Russian-born Australian team-mate.

However, Gavrilova could not follow suit, and succumbed to world No.166 Hradecka by the end of three sets, 4-6 6-4 6-4.

The mixed doubles was also a close game with the Czech team taking the win 3-4(1) 4-3(1) 4-2.

Australia lost its opening match to Spain 2-1.
