RESEARCH: Workin' the Split Shift 2: Pitchers

We follow up our look at 2H/1H splits for 2010 mid-season rookie batters (explained in last week's column) with a similar approach for pitchers. There are 10 profiles below of both starters (minimum 80 IP in 2010) and relievers (minimum 30 IP). Several of these had a cup of coffee before 2010; we looked for pitchers that had a more or less consistent role for approximately half a season last year. Our goal is to see what the BPI trends in a pitcher's "second half" (2011 numbers through 7/10) can tell us as we forecast the balance of this year and beyond.
