**Base Performance Value or BPV: This formula combines the individual raw skills of dominance, control and the ability to keep the ball on the ground, (all characteristics that are unaffected by most external team factors) is already a key stat in determining which pitcher’s are in trouble and which are throwing great. A BPV of 50 is the minimum level required for long-term success.
**Pure Quality Starts: The old Quality Start method — minimum 6 IP, maximum 3 earned runs — is simplistic and does not measure any real skill. Bill James' "game score" methodology is better, but is not feasible for quick calculation.
In PQS, we give a starting pitcher credit for exhibiting certain skills in each of his starts. Then by tracking his "PQS Score" over time, we can follow his progress. A starter earns one point for each of the following criteria...
1. The pitcher must have gone a minimum of 6 innings. This measures stamina. If he goes less than 5 innings, he automatically gets a total PQS score of zero, no matter what other stats he produces.
2. He must have allowed no more than an equal number of hits to the number of IP. This measures hit prevention.
3. His number of strikeouts must be no fewer than two less than his innings pitched. This measures dominance.
4. He must have struck out at least twice as many batters as he walked. This measures command.
5. He must have allowed no more than one home run. This measures his ability to keep the ball in the park.
A perfect PQS score would be 5. Any pitcher who averages 3 or more over the course of the season is probably performing admirably. The nice thing about PQS is it allows you to approach each start as more than an all-or-nothing event.
Note the absence of earned runs. No matter how many runs a pitcher allows, if he scores high on the PQS scale, he has hurled a good game in terms of his base skills. The number of runs allowed — a function of not only the pitcher's ability but that of his bullpen and defense — will even out over time.
