Félix Auger-Aliassime's run as top seed at the Libema Open in 's-Hertogenbosch, Netherlands, ended abruptly on Friday when Poland's Kamil Majchrzak defeated him 6-4, 6-3 in the quarterfinals. Majchrzak, ranked well outside the top 10, converted the upset in just 69 minutes by winning 85.1 per cent of his service points, according to Field Level Media. The victory marked Majchrzak's second career win over a top-10 opponent and sent him into his third career ATP semifinal.
The same week brought disappointment for Denis Shapovalov at the HSBC Championships in London. The Canadian fell to top-seeded Alex de Minaur of Australia 6-4, 6-1 in the second round on Wednesday at Queen's Club. De Minaur needed just 63 minutes to advance, committing only 11 unforced errors while Shapovalov struggled with 29 unforced errors and nine double faults, according to Field Level Media.
Auger-Aliassime's loss came after he had advanced through earlier rounds at the Libema event. Majchrzak will face the winner of a semifinal between No. 3 seed Daniil Medvedev and Marin Cilic, while de Minaur progressed to face Brandon Nakashima in the London quarterfinals.
The results underscore the competitive depth on the ATP Tour during the grass and indoor season, with both Canadians unable to maintain seeded positions at their respective tournaments.
