Most Yankees’ fans have probably been looking forward to 2012 since Alex Rodriguez swung and missed at the last pitch of the 2011 ALDS, but with a New Year fast upon us, what better time to take one last look back at the 2011 season? Instead of getting bogged with subjective recollections of the year’s most significant moments, it’s much simpler to let Win Probability Added (WPA) do all the heavy lifting. After all, with over 6,300 plate appearances to recall, more than a few high highlights, and low lights, might be dimmed by the shortcomings of memory.

Looking at the graph above, it’s easy to see why so much of a baseball season can seem like a blur. Over 57% of Yankees’ plate appearances registered a WPA of 2% or less, while 84% of trips to the plate moved the needle by 5% or less. Of course, without all of these seemingly inconsequential moments, the dramatic events that exist as outliers wouldn’t be possible. Listed below are those highlights and lowlights, both ranked by WPA.
