Yun Sung-bin of South Korea extended his lead at the top of the overall standings as he set a track record on his way to victory at the International Bobsleigh and Skeleton Federation World Cup in St Moritz.
The South Korean star secured his fifth win of the season in the men's skeleton event as he continues to demonstrate his medal credentials in the build-up to competing at his home Winter Olympic Games in Pyeongchang next month.
Yun broke the track record with his second run of 1min 07.19sec as he finished with a combined time of 2:14.77.
Axel Jungk of Germany was 0.87 seconds adrift in silver medal position, while defending World Cup champion Martins Dukurs of Latvia was third.
The result saw Yun strengthen his position in top spot on the leaderboard as he has 1,545 points going into the season finale in Königssee in Germany next week.
Dukurs, who has amassed 1,430 points, remains in contention but is in danger of losing his crown.
Jungk is third on 1,282 points but is some way adrift of the two who are battling for the overall title.
Janine Flock of Austria sealed the women's skeleton honours as she claimed her second win of the campaign.
The 2014 and 2016 European champion recorded a combined time of 2:19.44 to beat Germany's Tina Hermann, who was 0.42 slower in second place.
Elisabeth Vathje of Canada did enough for third place as she clocked 2:19.89.
Vathje's team-mate Mirela Rahneva was unable to clinch a podium finish despite registering a track record of 1:09.35 in her second run as she ended up fourth.
Jacqueline Lölling of Germany, sixth in today's event, remains the overall leader on 1,403 points.
Vathje follows in second as she has 1,318, while Hermann is third on 1,294.
