Well maybe we at Brewerfan should try to develope our own defination of clutch or Clutchness. Here are a few problems I see: RISP is not a good measurement. A guy batting with a man on second and down by 8 runs is not clutch regardless of the outcome. This is an extreme, but at what point do you make a distinction. 3 runs down in the ninth, 1 run down in the ninth? Also reaching base in the Ninth inning is huge if your down by one run regardless of the number of outs or men on base. I propose this, but much more input is necessary. Also I do not have the resources for this formula. We would start by defining clutch situations. Like the following Ninth inning situations --1 run or less Any situation --2 runs Man on first --3 runs Two men on --4 runs 3 runs on and so on for the 8th and 7th innings. After all this I must admit, I do not think clutch exists in baseball, but sometimes watching Big Papi makes me believe.
