World Cup leader Martins Dukurs of Latvia has extended his advantage following another victory at the International Bobsleigh and Skeleton Federation (IBSF) World Cup event in St Moritz.

Dukurs, the defending World Cup champion, secured his fifth win of this season after breaking the season track record of 1min 07.25sec in his second run.

Combined with his first attempt, the nine-time European champion produced an overall time of 2:15.10 to claim victory. 

Sungbin Yun of South Korea secured his country's first ever World Cup victory in skeleton on the track in last year. 

He failed to repeat that today despite leading after the first run.

His second attempt could not match Dukurs' as Yun finished in second in a time of 2:15.13.

Third place was claimed by Nikita Tregybov of Russia in 2:15.65, as he finished on the podium for the first time this season.

Dukurs now has 1,036 points while Yun remains in second on 1,003 in the overall standings.

Christopher Grotheer of Germany, who finished eighth today, is third overall on 897 following the fifth of eight World Cup races this season.

In a surprise result, second was taken by Kendall Wesenberg of the United States who collected her first ever podium finish in the World Cup in 2:18.36

Janine Flock of Austria, who won the World Cup and European Championship in St Moritz last year, finished third 1.98 behind.

Despite finishing eighth, European Champion Jacqueline Lölling of Germany continues to hold the top spot in the overall standings on 989.

Flock cut the gap between herself and Lölling and remains second overall on 953.
