In 2016, Sinclair formed a new team with Alexandra Carlson, Vicky Persinger and Monica Walker. Sinclair found much more success with her new team, winning the 2017 U.S. Championships, but missed out on going to the World Championship due to Nina Roth earning more points throughout the season. They also played for the winning North American Team at the 2017 Continental Cup of Curling and made it to the quarterfinals of the last Grand Slam of the season, the 2017 Humpty's Champions Cup.
