Kyrgios stuns opponent with amazing tweener

Nick Kyrgios has continued his on-court showmanship with an amazing tweener shot during a winning rally at the Japan open.

The Australian sixth seed is on track for his third title of the year, winning through to the semi-finals of the Japan Open with a 6-4 6-2 win over Gilles Muller of Luxembourg.

The world No.15 breezed through to the last four in just 70 minutes on Friday to set up a last-four showdown with French second seed Gael Monfils, who had to fight hard to beat No.7 Ivo Karlovic of Croatia 7-6 (8-6) 7-6 (8-6).

Resting up after a quarter-final walkover against Czech Radek Stepanek, Kyrgios laid on a serving spectacle by hammering 18 aces at the Ariake Colosseum.

"I thought I played great today," Kyrgios said. "I served well, returned well and my engagement level was really good the whole time."

The Australian holds a 36-14 win-loss record for the season ahead of his sixth semi-final of 2016. He has already won titles this year in Marseille and Atlanta.
