In Manhattan Sinclair made an immediate impact scoring 18 goals as a rookie and playing in the NHL All-Star Game. The following year Sinclair hit the 20-goal plateau and once again represented the Broadway Blueshirts at the All-Star game. Despite his scoring prowess, his time in New York was over. The Rangers traded Sinclair and Johnny Morrison to the Detroit Red Wings on August 18th 1952 in exchange for All-Star defenseman Leo Reise, Jr.
With the Red Wings Sinclair was unable to duplicate his previous production and only scored 11 goals and 23 points. Sinclair played three playoff games with Detroit and contributed 1 goal. The playoff contests ended up being Sinclair's last games as a professional player as he retired following them.
