Understanding Baseball Stats: What Does “PP” Mean?

Baseball is a game filled with statistics, and understanding these stats is crucial for fans and players alike. One commonly used stat is “PP,” which stands for Pitching Performance. In this blog post, we will explore what “PP” means, how it is calculated, and its significance in evaluating a pitcher’s performance.

What Does “PP” Mean?

“PP” is a baseball statistic that measures a pitcher’s overall performance in a game. It takes into account several factors such as earned runs, innings pitched, strikeouts, and walks. The formula to calculate “PP” is as follows:

PP = (ER – HR) / IP + K – BB


  • ER = Earned Runs
  • HR = Home Runs
  • IP = Innings Pitched
  • K = Strikeouts
  • BB = Walks

Understanding the Formula

The “PP” formula may seem complex at first glance, but breaking it down helps in understanding its components. Earned Runs (ER) refer to the number of runs a pitcher allows that are solely the result of his own performance, excluding errors by fielders. Home Runs (HR) represent the number of times a pitcher surrenders a home run. Innings Pitched (IP) indicate the number of complete innings a pitcher has thrown. Strikeouts (K) refer to the number of opposing batters a pitcher has struck out, and walks (BB) represent the number of batters a pitcher has walked.

By subtracting home runs from earned runs, we eliminate the runs that were a result of home runs and focus solely on the runs allowed due to a pitcher’s performance. This adjustment is necessary to provide a more accurate assessment of a pitcher’s overall performance.

The “PP” formula also takes into account strikeouts and walks. By adding strikeouts and subtracting walks from the equation, we reward pitchers for their ability to strike out batters and penalize them for issuing walks. This adjustment further enhances the accuracy of the “PP” stat.

Significance of “PP”

“PP” is a valuable stat for evaluating a pitcher’s performance as it takes into account multiple factors that contribute to their effectiveness on the mound. A higher “PP” indicates a stronger performance, while a lower “PP” suggests a pitcher had difficulties during the game.

Comparing “PP” between different games allows us to analyze a pitcher’s consistency. If a pitcher consistently has a high “PP” across multiple games, it shows that they consistently perform well. On the other hand, if a pitcher’s “PP” fluctuates greatly from game to game, it may indicate inconsistency in their performance.

“PP” is also useful when comparing pitchers. By comparing the “PP” of two pitchers, we can determine which one had the better performance in a specific game or season. This helps in evaluating and ranking pitchers based on their overall effectiveness.


Understanding baseball stats like “PP” is essential for gaining insights into a pitcher’s performance. By knowing what “PP” means, how it is calculated, and its significance, fans and players can better analyze and appreciate the game of baseball. So next time you hear the term “PP” being mentioned, you’ll know exactly what it means!
