Remember 2007? Justin Bieber was unknown, your house was worth something and Jake Peavy won the NL Cy Young Award. In the four seasons since, Peavy, 30, hasn't made 30 starts or pitched 180 innings, and in the last three years he's thrown 320 innings total. In that time he's been on the DL for a strained left elbow, a strained right ankle, shoulder surgery and a groin strain. The White Sox are hopeful that this is the season Peavy returns to the form of '07, but when a pitcher has this many ailments over this many years, it's fair to ask whether he can physically handle being a starter. Normally converting a starter to a reliever is a mistake; the value of the innings lost in the transaction isn't made up by the increased leverage of the ones he pitches. But Peavy has the fastball velocity and the excellent slider to be a wipeout reliever, and if he's only going to throw 120 innings as a starter—which recent history suggests is the case—the White Sox would gain by having him throw 80 high-leverage innings out of the bullpen.
