Stoch’s triumph, hot on the heels of his victory in the Four Hills tournament earlier this week, saw him equalling legendary Polish jumper Adam Małysz’s record of 39 wins in World Cup competitions.
Saturday’s event saw an exceptional performance by team Poland, with Andrzej Stękała finishing fifth, Dawid Kubacki seventh, Jakub Wolny 11th and Paweł Wąsek 28th.
Norway’s Halvor Egner Granerud came second.
Kubacki had been leading after the first round but hit difficult conditions on his second jump.
