Defending champion Nick Kyrgios has made light work of Norbert Gombos to reach the Open 13 semi-finals, beating the Slovakian qualifier 6-3 6-3 in less than an hour.
The third-seeded Australian hit 15 aces and lost just six points on his serve to set up a first career meeting against second-seed Jo-Wilfried Tsonga.
"I thought I served and returned really well today," Kyrgios said.
"All that matters is that I'm going out there and playing every point hard. I think I'm pretty aggressive on my returns."
Meanwhile, Tsonga came out on top in an all-French matchup by defeating two-time champion Gilles Simon 6-4 6-1.
