 Each time the pitcher surrendered a hit, walk, run, wild pitch, or hit batsman, his rating would be reduced by one point (e.g., a walk and then a home run would be 4 points - one each for the walk and the hit, and then two for the runs scored).Once a pitcher's Reduction Rating reached zero, a PB number would no longer be drawn for each hitter—instead, all at-bats would begin with a FAC Random Number draw being compared to the hitter's card.Because of this, it was usually advisable to remove a pitcher once his reduction hit zero (or even before).
