A very basic stat for your Monday morning, since we were curious about it and decided to delve into it:

Since 2011, also know as the beginning of the end for the Twins, there have been 182 games in which Joe Mauer has not started (regardless of whether he was playing catcher, DH or first base).

There have been 408 games in which he has started. The Twins' records, year-by-year and cumulatively, games he has started and not started are as follows:

2011: Started — 31-47 /// Not started — 32-52

2012: Started — 57-87 /// Not started — 9-9

2013: Started — 49-61 /// Not started — 17-35

2014: Started — 36-40 /// Not started — 11-17

Total: Started — 173-235 /// Not started — 69-113

The winning percentage in games Mauer has started is .424, and in games he has not started it's .379. Over the course of a full season, that's the difference between about a 68-win team and a 61-win team.

Surely there are many more factors than that, but it is a large enough sample size to draw a conclusion that we inherently already knew: the Twins miss Mauer when he's not in the lineup, even if he is struggling like he was for much of this season, and his absences have certainly contributed to making a bad team even worse.
