Great Question! You'd have to go all the way back to 1945, the last time the Cubs got into the World Series. Ray Prim led the National League with a 2.40 ERA. His teammate, Claude Passeau was runner-up with a 2.46 ERA.However, this wasn't good enough to lead the ERA in the majors that year. There were 4 pitchers from the American League that has better ERA's that that.For the leader of the Majors, you'd have to go back to 1938, when teammates Bill Lee and Charlie Root led the Major League in ERA with a 2.66 and 2.88 respectively.
