A commonly accepted feature of commonsense morality is that there are some acts that are supererogatory or beyond the call of duty. Recently, philosophers have begun to ask whether something like supererogation might exist in other normative domains such as epistemology and esthetics. In this paper, I will argue that there is good reason to think that sporting supererogation exists. I will then argue that recognizing the existence of sporting supererogation is important because it highlights the value of sport as (...) a mutual pursuit of excellence and reinforces the value of sportsmanship.
