I made this over at DRaysBay and figured I'd share. A quick explanation of my pitch type linear weight methods from a previous article: "For balls, strikes, and fouls, I used Joe Sheehan's numbers on Baseball Analysts. For balls in play, I used the numbers given by Tango in this thread of The Book Blog. Note that those numbers are a departure from the pitch type linear weights listed on Fangraphs, as Fangraphs uses the run value of the outcome of batted balls, not just the average run value of the batted ball type. Also note that in these calculations, the balls, strikes, and fouls are adjusted for count; the balls in play are not." In the pitch type linear weights, a negative number is good for the pitcher, and is the number of runs that pitch has saved. Enjoy him.
