London 2012 Olympic champion Oh Jin-hyek of South Korea topped the men's recurve qualification round in windy conditions at the Archery World Cup in Berlin.
Oh completed the round with a score of 654 out of a possible 720 points as the weather played havoc on the opening day of competition at Maifield in the shadow of the famous Olympiastadion.
The South Korean star's total was matched by Kao Hao-Wen of Chinese Taipei but Oh claimed top spot by virtue of shooting more 10s.
Mete Gazoz of Turkey did enough for third on 653 points.
In women's recurve qualification, Oh's team-mate An San finished first on 649 points, while Chinese Taipei’s Lin Chia-En was a point adrift in second.
China's An Qixuan was third having scored 644 points.
The conditions also caused problems in the compound event as Colombian Sara López took first place on 687 out of a possible 720 points as wind speeds reached 25 kilometres per hour.
Yeşim Bostan of Turkey will be seeded second after she finished nine points behind and Sophie Dodemont of France was third on 671 points.
In the men's event, Domagoj Buden of Croatia led the way on 691 points as he beat world number one Mike Schloesser of the Netherlands to the top seeding by a point.
Germany's Marcus Laube rounded out the top three with 689 points.
The event, where places at the Archery World Cup Final are up for grabs, is due to continue tomorrow.
