In 2015, Hamilton joined the Jamie Sinclair rink as her second. At the 2016 United States Women's Curling Championship, they would finish in fourth place. She would only play with Sinclair for one season before returning to the Spatola (now Roth) rink, throwing lead rocks. The team were runners-up at the 2017 US Championships, but represented the United States at the 2017 World Women's Curling Championship, finishing in sixth place.
