The Australian earned his 200th tour-level hard-court win in his first-round victory against Roman Safiullin and quickly made it 201 with a controlled 6-4, 6-4 victory against Dutchman Van de Zandschulp.

The second seed demonstrated trademark lighting speed at times in Doha, where he flew around the court to track down Van de Zandschulp’s flat groundstrokes. The Aussie also saved all four break points he faced, advancing after two hours. 

De Minaur has earned a Tour-leading 13 victories in 2025, having reached the quarter-finals at the Australian Open for the first time and the title match in Rotterdam. Chasing his first trophy of the season, the No. 8 in the ATP Rankings will next meet Andrey Rublev at the ATP 500 after the fifth seed beat Nuno Borges 6-3, 6-4.

Rublev triumphed in Doha in 2020 and will be aiming to build on recent runs to the semi-finals in Montpellier and quarter-finals in Rotterdam.

In other action, Daniil Medvedev wasted little time in reaching the quarter-finals. The fourth seed dispatched Zizou Bergs 6-2, 6-1 in just 56 minutes to earn his 300th tour-level hard-court win.

The 29 year-old arrived in Doha holding a 4-3 record on the new season. Aiming to rediscover form this week, the 2023 champion committed just six unforced errors compared to 29 from Bergs to back up his opening-round win against Karen Khachanov.

Medvedev will next meet Felix Auger-Aliassime in the last eight. The Canadian received a walkover from Hamad Medjedovic earlier in the day. The Serbian rising star suffered a hamstring injury in the latter stages of his win against Stefanos Tsitsipas and was forced to withdraw from the ATP 500 event ahead of his meeting with Auger-Aliassime.
