WANAKA, New Zealand (AP) -- Torin Yater-Wallace and Devin Logan gave the United States a sweep of the first Olympic qualifying event for halfpipe skiing, which makes its debut at the Sochi Games in 2014.

Yater-Wallace and Logan won Wednesday in New Zealand to kick off a 17-month period during which skiers have a chance to make their Olympic teams.

Logan's victory in the women's competition and Yater-Wallace's first-place finish in the men's gave the Americans wins in the last six World Cup events in ski halfpipe, dating to March 2011.

Olympic officials have added a number of sports for the next Winter Games, including snowboarding slopestyle and halfpipe skiing.
