It felt like walks were down in baseball this season. A lot of pitchers have some really low walk rates -- more than usual it seemed. I decided to see if there was anything to it.
Not sure if this is a trend or just fluctuation, as the pitches/PA are actually up a bit. But interesting nonetheless:
Prior to 2009, it was mostly hovering around 8.3-8.6% (although 2008 was under 8%).
Perhaps this has something to do with home runs continuing to go down, so pitchers aren't as reluctant to throw the ball in the zone when needed.
