The Statcorner/Lookout Landing crew lists the win values of pitchers last year, just based on their hitting. As we know, Zambrano is just a monster. It's interesting to note that you can probably deduct a half win or so from Sheets's value, he was the fourth worst at about -.5 wins last year. Dave Bush was down there as well, Manny Parra checked in around +.5. It's an interesting reference for the value of pitchers hitting. I was surprised that there can be a full win of difference between a good and bad hitting pitcher.
