Maybe Zito isn't 'Back to His Old Habits'
May 9, 2009 4 Comments
So I probably should be studying for finals, but FanGraphs has really been getting in the way of that. I was looking at the team leaderboards under infield fly % (riveting stuff, I know), and noticed something odd. In 2009, the lowest team IFFB% is 11.9%. The bottom 5 are all between that and 15.1%. In 2008, the highest team IFFB% was 12.1%. Just eye-balling it, the data from 2004-2008 is all very similar, but there’s a huge jump in 2009 for whatever reason. 2002 and 2003 are slightly higher than ’04-’08, but only by a tiny amount.
This reminded me of Eric Seidman’s Zito post on FanGraphs from a few days ago, which focused a lot on Barry Zito’s IFFB% (why do I always quote other StatSpeakers? It’s getting kind of weird at this point). If that stat is inflated in general, then maybe Zito isn’t doing anything differently, it’s just that his data are inflated along with the rest of the league’s.
This is just something I noticed and wanted to throw up on here (not literally) to maybe get some feedback. Once I have some more free time, I’ll look deeper into this and see what the full effect really is.
