Australian sixth seed Nick Kyrgios has won 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 has breezed through to the last four in just 70 minutes and will face French second seed Gael Monfils or No.7 Ivo Karlovic.
Fourth-seeded Croatian Marin Cilic warmed up for next month’s Davis Cup final, crushing Argentina’s Juan Monaco 7-5 6-1 to reach the semi-finals to take on Belgian fifth seed David Goffin – a 1-6 7-5 6-2 winner over Joao Sousa.
While the 89th-ranked Monaco is unlikely to figure heavily in a squad which will be headed by Juan Martin del Potro, victory will still boost the confidence of Cilic, who hopes to help his nation to a second Davis Cup title after a maiden win in 2005.
The November 25-27 final will be played in Zagreb.
Cilic has boosted his chances of claiming one of the eight spots for the season-ending ATP World Tour Finals, to be played in London in the week before the Davis Cup showdown.
Cilic stands provisionally 10th in the race to London and, by winning the Tokyo title, he can move to ninth in the chase.
