Watertown did not participate in the first World Series of Pro Football, instead loaning its entire backfield to the Syracuse Athletic Club for its entry into the tournament. Watertown participated in the 1903 tournament, finishing second to the Franklin Athletic Club, to whom the Red & Black lost, 12-0. During the 1903 season, the Red & Black defeated a team from Cortland, New York by a score of 142-0, the second-highest in football history (behind only a 148-0 win by the Massillon Tigers over a team from Marion, Ohio a year later). In 1919, the team participated in the New York Pro Football League playoffs, losing in the regional quarterfinals ("Central New York Championship") to Syracuse.
