Total player rating (TPR), also known as Batter-Fielder/Pitcher Wins (BFW/PW) is a metric for measuring the value of baseball players, and to enable players to be compared against each other even when they played for different teams, at different positions, and in different eras. It was developed by sabermetrician Pete Palmer and was popularized in the Total Baseball series of encyclopedias during the 1980s
