Lindholm: The Baseball Mistake Index

From Scott Lindholm at Beyond the Box Score on December 16, 2013:

Every spring training the same phrase is utered by every member of every MLB coaching staff–“We’re going to focus on the fundamentals.” I developed a measure over the last couple of years which puts all the bad things teams can do in one place to see if there is a relationship between sound fundamentals and winning.

In my former blog I called it the Mistake Index and you can still see it in its complete version here, but I’ll discuss a truncated version in this post. I’ll begin with this chart for the American League.


Runs and earned runs are usually shown but unearned runs are rarely shown on their own, and the relationship between errors and unearned runs is historically around 55-57% of errors become unearned runs. Hit-by-pitch, balks, wild pitches and pickoffs are common stats, and OOB is the number of times base runners are thrown out trying to advance on the bases. Team and individual data for this last stat can be seen on this Baseball-Reference page.
