Former world champion Sébastien Peineau of France crashed out of the men's compound competition at the second-round stage as he was beaten by Australia's Adam Bielby at the Archery World Cup in Berlin.
The Frenchman, who claimed the world title in 2017, was on the wrong side of a 140-139 scoreline at Maifield in the shadow of the famous Olympiastadion.
Defeat ended Peineau's pursuit of gold in the German capital and saw Bielby march on to a meeting with Jozef Bosansky of Slovakia.
There was also a surprise in the men's recurve tournament as Steve Wijler of the Netherlands, who won the Indoor World Cup title earlier this year, was knocked out in the second round.
The rising Dutch star was beaten by Jonathan Vetter of Germany on a tiebreak.
Vetter's reward is a clash with American Matthew Requa, who overcame India's Atanu Das 6-2.
Lisa Unruh of Germany was among the archers to reach the third round of the women's recurve event as the Olympic silver medallist defeated Ukraine's Solomiya Trapeznikova 6-5.
The seeded athletes will return to action when competition resumes tomorrow.
