Masters of Deception

New, 7 comments

J.P. Howell has been the most deceptive pitcher in 2009, Daniel Cabrera the least.

I'm defining deception in a simplistic manner: called strikes per takes. But, it's calculated by count, relative to the league average and weighted (by the number of takes in that count against the specific pitcher).

So, league averages for called strikes per takes by count. Individual averages calculated the same way, the league average subtracted out and the resulting value divided by the league average. There you have called strikes per take above average (CSpTAA) by count which you then use to create a weighted average for each pitcher. Top, and Bottom, 20 after the jump.

The deception, as I'm calling it, can be from selection, movement or location. Who knows. When creating metrics like this in the past, I also included swings out of the zone. That should be included in this somehow, but I like the simplicity of this approach (for now).

Updated: see the comments for these #'s corrected for control.
