Sosa had been yet to earn a medal in the World Cup during his career, but produced a strong performance in the men's trap event at the Code Paradero Shooting Range.

He went head-to-head with Italy's Emanuele Buccolieri in the closing stage of the final, with the two men entering the last 10 targets tied on a score of 36.

The Luxembourger was appearing in his first final since 2014, when he ended in fourth place in the 2014 World Championship in Granada.

Sosa was able to hold his nerve during the final shots, hitting each of the final 10 targets to secure a historic gold.

Buccolieri was forced to settle for the silver medal, after a late missed target meant he ended one point behind the winner.

The Italian managed to hit 45 of his 50 targets in the final.

The podium places were completed by Finland's Vesa Tornroos, who claimed the bronze medal with 32 of his 40 targets hit.

He held off the challenge of Yannick Peeters of Belgium, who was third with 28 targets hit out of 35.

Competition will continue tomorrow in Guadalajara with the mixed team trap final.
