Brogan Crowley shattered her personal best of ninth in Konigsee last weekend to finish fifth.
Ashleigh Pittaway was 10th – and it was just the second time Britain have had three female sliders in the top 10 of a World Cup since Lizzy Yarnold took gold, Rose McGrandle took bronze and Deas finished seventh in Igls back in 2015.
Deas was +1.09 secs slower as Russia’s Elena Nikitina took gold ahead of home favourite and overall World Cup winner Janine Flock, with Kimberly Bos finishing third.
