Australian No.2 John Millman has crashed out of the Stockholm Open, going 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 quarter-finals of the US Open, came through a tough test when he battled back from a set down to beat Russia's Alexei Popyrin on Tuesday.
However, 20-year-old world No.16 Tsitsipas proved to be a step too far for the Queenslander as he reeled off three successive games to seal victory in the third set in just over two hours.
Nick Kyrgios is in action at the Kremlin Cup on Thursday when he plays Bosnian world No.76 Mirza Basic for a place in the quarter-finals.
