The first column indicates the total number of pitches the batter has taken outside of the pitchFX defined strike zone. The second column shows what percent of taken pitches out of the strike zone were called strikes. Six New York Mets made the list - that's nearly a quarter of the top 25. Call it the Madoff effect. Oakland comes in second with 4 batters making the list. The majority of these pitches are located off the outside edge of the zone as the following graphic indicates.
Here's a list of the batters that have had the least "non-strike" strikes called against them.
