Chicago Cubs, Milwaukee Brewers hold respective edges entering 2018

Chicago leaps-and-bounds ahead of the division

Figure 4: Combined Infield-Outfield Comparison

Viewing the findings of this exercise in this context serves as somewhat of a validation of the process. There shouldn’t be much argument that, in ordering the units from best to worst, the list is topped with the Cubs infield with the Brewers outfield.

It may be somewhat of a surprise to view the Cubs outfield as the next-best unit. However, when you consider what sabermetrics truly value – great defense, ability to get on base while still producing runs – you realize that reality may not necessarily match the narrative. Continuing down the list, calling out Pittsburgh’s infield as the worst single unit in the division also turns heads.

As an aside, Theo Epstein’s ability to recognize and understand the value of analytics in developing a roster is clearly evident. It’s these finer points, not big names and gaudy stats, that win you championships. It may explain why Theo has been consistently successful as a general manager, as well.
