KD is one of baseball statistic which is popular to certain internet people in Japan. It is calculated with a simple formura as below :
It is quite different from the concept of sabermetrics. But interestingly, KD clearly shows the pitcher's impression , impact or contribution to the team. And KD can compare pitchers with different role : starter, setup man and closer.
In 2011, Satoshi KOMATSU ( ex Orix Buffaloes picher, NPB ) started his contribution activity named "ONE OUT DONATION". He donated amounts calculated from his pitching results to a charity group.
KD formula (seen above) is based on his method of calculating donation amounts.
