Qureshi and Rojer will face Nick Kyrgios and Jackson Withrow for a spot in the semi-finals. The Australian-American duo defeated German wild cards Matthias Bachinger and Yannick Maden 7-5, 7-6(7).

Third seeds Max Mirnyi and Philipp Oswald took just 65 minutes to win their first-round clash against Hugo Nys and Denis Shapovalov 7-5, 6-3. Mirnyi and Oswald won 85 per cent of first-serve points (34/40) to confirm a quarter-final clash with Robert Lindstedt and Marcin Matkowski.

Inglot/Skugor Reach Semi-finals
Gazprom Hungarian Open champions Dominic Inglot and Franko Skugor scored another straight-sets victory in 's-Hertogenbosch, defeating Fabrice Martin and Purav Raja 7-6(6), 7-5.

The British-Croatian duo advanced after 89 minutes, saving all five break points they faced in a tense quarter-final encounter. Inglot and Skugor had lost their past two matches prior to entering the tournament, but have refound the level that saw them lift their first team title in the Hungarian capital in April.

Inglot and Skugor will meet top seeds Lukasz Kubot and Marcelo Melo or Dutch duo Sander Arends and Matwe Middelkoop for a place in the championship match.
