Daria Gavrilova’s Kremlin Cup campaign ¬†came to an end at the hands of Britain’s Johanna Konta in the round of 16.

Gavrilova, a finalist at the event in 2016, went down 6-4 3-6 6-3 to the Sydney-born Konta on Wednesday in the Russian capital.

Nick Kyrgios remains alive in the tournament; he plays Bosnian world No.76 Mirza Basic for a place in the quarterfinals.

In Stockholm, Australian No.2 John Millman went down to exciting young Greek Stefanos Tsitsipas 6-4 3-6 6-3.

MIllman, who has been struggling with a hip injury since his run to the quarterfinals of the US Open, came through a tough test when he battled back from a set down to beat countryman Alexei Popyrin on Tuesday.

However, 20-year-old world No.16 Tsitsipas – the third seed in Stockholm – proved to be a step too far for the Queenslander.

Tsitsipas reeled off three successive games to seal victory in the third set in just over two hours.
