Roman Koudelka claimed his second win of the FIS Ski Jumping World Cup season in Sapporo on Sunday.

The Czech edged Poland's Kamil Stoch and Slovenian Peter Prevc in the HS134 event in Japan.

Koudelka was fourth after the first jump, but his second set up a total of 282.9 points.

Stoch led at the halfway mark before falling just short of Koudelka, totaling a tally of 278 points.

Prevc (277.3 points) was third.

Championship leader Stefan Kraft was fourth in Sapporo as Prevc cut his lead atop the standings to 83 points.

Koudelka is fourth overall, just behind Austrian Michael Haybock - who was 10th in Japan.
