Clutch Pitching
Fangraphs now has clutch pitching stats. The sum of the PA by PA WPA/LI is under the column WPA/LI. In 2007, Putz was +2.4 wins. In 2006, he was +2.3 wins. This is a context-specific performance, but with the leverage aspect depressed. The sum of WPA divided by the average LI gives you the expected WPA/LI, based on how he pitched. The difference between this number and the WPA/LI is his clutch number. In 2007, Putz had a clutch wins of +1.2 wins. Basically, if you look at how he performed with the LI of 2.0 or greater, he was likely unbelievable. You can get the leaderboards for this stat. What this will give you is essentially those pitchers that performed great in the high LI situations and/or really bad in the low LI situations.
