NOTE: I really thought this was something new. I heard it on BP radio this morning and after I did all the stat leg work and typed up this post, I did a google search and found this article from 2004
Anyway, I know I'm a newbie to numbers, but I still found it interesting. Instead of WHIP which sticks pitchers for hits even when the fielder misjudges the play or dives and comes up short, SWIP (for those like me who were uneducated until today) = Strikes Outs - Walks / Innings Pitched. The thinking is it measures (1) the pitcher preventing hits in the manner over which he has the most input (2) the pitcher putting men on base in the manner over which he has the most controll. It does favor power pitchers over contoll guys. The higher the SWIP the better.
The radio show pointed out a list of pitchers with medicore WHIP but were basically productive pitchers. Typically their SWIP's were good. I can't remember any of those names now.
Anyway, probably old news to all of the numbers folks, but I thought it was interesting. Here's the numbers from the Reds pitchers last year, along with Saarloos and Santos. Also, threw in some comparisions.
