File my latest at Hardball Times under “D” for “duh”: Three years ago I studied Petco Park’s effect on offense. The results — that it kills offense — matched what my eyes told me, which is always nice. Now, with three more years of data, I’ve revisited the earlier study and found that most of the findings still hold true.
Two items of particular interest are Petco Park’s effect on triples and walks. Triples have become a less frequent occurrence at Petco Park every year since its inception (Petco Park is the only venue to see consistent movement in one direction throughout the 2004-2009 period). Walks are all over the map: In 2007, Petco Park was the 28th toughest place to draw a walk; in 2009, it was the easiest. Go figure.
Anyway, go read the entire article. You’ll be glad you did.
