Fenson and his team missed the playoffs at the first three events for their 2011–12 World Curling Tour season. However, they had better fortune at the Laphroaig Scotch Open, where they flew through the knockout round and defeated David Brown in the final to win the event. Fenson and his rink were selected to represent the United States at the 2012 USA-Brazil Challenge to play against Brazil for a spot in the World Championships in Basel, but Brazil withdrew from the challenge. Fenson then participated in the 2012 Continental Cup of Curling, where Team World won a close tournament over Team North America. Fenson participated in the 2012 United States Men's Curling Championship, and went through the round robin with a 9–1 win-loss record. In the playoffs, he was defeated by Heath McCormick, who had previously beaten him in the round robin, but rebounded with a win in the semifinal over former teammate John Shuster. In the final, he lost a close game to Heath McCormick, losing his bid for a third consecutive nationals title and a chance to play at the world championships.
