Félix Auger-Aliassime's run at the Libema Open in s'Hertogenbosch ended in the quarterfinals when Poland's Kamil Majchrzak defeated the Canadian 6-4, 6-3. The upset marked Majchrzak's career-best victory, propelling the 76th-ranked player into the semifinals.
How Majchrzak won the match
Majchrzak broke Auger-Aliassime's serve twice to secure the opening set, converting his second break point in the closing games. In the second set, a service break midway through proved decisive, allowing Majchrzak to manage his lead through to victory.
Majchrzak's path to the semis
The Polish player reached his third career semifinal with the upset. He had previously advanced to the semifinals at Pune in 2022 and Marrakech in 2025. Earlier in the week, Majchrzak defeated Otto Virtanen 6-7(7), 6-4, 7-6(4) and James McCabe 6-0, 6-3 to reach the quarterfinals.
What's next
Majchrzak will face the winner of the Medvedev-Cilic quarterfinal in the semifinals. The Polish player's run follows a promising grass-court debut the previous week at the Birmingham Challenger, where he also reached the semifinals.
