The aim of this paper is to analyse the concept of advantage in sport. Advantage is often referred to in discussions of the philosophy of sport, but only a few analyses of the term exist. Sigmund Loland has discussed advantage most comprehensibly. Nevertheless, his view does not address all of the relevant kinds of advantage. I begin with a summary of Loland's view and then show its limitations. I continue by developing his ideas further to present what I call performance (...) advantage, a comparative relationship between numbers attributed to performances. For instance, the performance of a football team that beat its opponent 3?2 is given a numerical value. However, another kind of advantage exists, one that I label property advantage. This term refers to advantage as a comparative relationship between different properties that affect performances. For example, a runner may have more haemoglobin than his or her competitor. I then outline the relationship between the two meanings of advantage. Finally, I summarise by stating that advantage in sport is a relationship of superiority that can be divided into performance advantage and property advantage. (shrink)
