The team found more success in the 2013–14 season. They won one World Curling Tour (WCT) event over the season, the 2013 Kamloops Crown of Curling. Their success on the World Curling Tour gave them enough points to qualify for the 2014 Ford World Women's Curling Championship, following new rules made by the United States Curling Association which based World Championship qualifying on Order of Merit points rather than winning the U.S. Championship.
