FORMULA #17:
PITCHER'S DOUBLE
psomD=((D*216)ITBF).90
pitcher's som DOUBLE equals ((doubles yielded times 216 ) divided by Total Batters Faced) minus 90

FORMULA #18: PITCHER'S TRIPLE
psomT=((T*216)ITBF)~15
pitcher's som TRIPLE equals ((triples yielded times 216) divided by Total Batters Faced ) minus 15

 

FORMULA #19:
PITCHER'S HOMERUN
psomHR = (( HR* 216)ITBF) - 50
pitcher's som HOMERUN equals ((homeruns yielded times 216) divided by Total Batters Faced ) minus 50

How it works: These formulas take the extra base hit and multiply it by the 216 chances appearing on both cards. Then the figure is divided by the pitcher's Total Batters Faced. The result is then subtracted by the amount of double, triple, or homerun subchances appearing on the average batter's
card. The 90, 15, and 50 in these formulas are the defaults to be used in the absence of more precise league-wide data.
For advanced-side ratings, remember to run the formulas 4 ways - leftyAL, rightyAL, leftyNL, and rightyNL. For pre-1990 cards, or if double and triple data is not available (get US Today's Baseball Weekly), use these older formulas for deter-mining psomD and psomT:

old FORMULA #17:
PITCHER'S DOUBLE
psomD = psomHR * 1.8
pitcher's som Double equals pitcher's som HomeRun times 1.8

old FORMULA #18:
PITCHER'S TRIPLE
psomT = psomHR * .4
pitcher's som Triple equals pitcher's som HomeRun times OA

How it works: These formulas were 95 percent accurate for the pitcher's elementary cards until 1990. It's still essential to have the pitcher's HR and TBF.
