Earned Run Average (ERA)

ERA = (Earned Runs / IP) * 9

ERA is one of the oldest pitching metrics still used today. It simply is the average of earned runs given up by a pitcher per nine innings (i.e. the traditional length of a game).

Like a golf score, the lower it is… the better!

Ken Sanders pitched for The Brewers for three years (1970-1972)
