With less than three months until baseball returns to Chicago, I thought it would be a good time to revisit, for the first time in six years, the all-time rankings in both offensive and defensive categories for all iterations of the current 30 teams for the 1040 games I’ve identified that I have attended. We wrap up the defensive side of the ball today with earned run average.
Both the White Sox and Cubs find themselves in the middle of the pack for team ERA, with the Cubs coming in at 14th with 4.00 and the White Sox at 17th with a team ERA of 4.20. The Anaheim iteration of the Angels lead the way, finishing mere percentage points below 2.60. The Devil Rays are on the opposite end of the spectrum, clocking in just over 5.95.
