Pitching Statistics

In this tutorial, we will learn about pitching statistics in baseball.

Innings pitched (IP)

The number of innings in a game a pitcher pitched.

Hits (H)

The total number of hits opposing batters got against a pitcher.

Runs (R)

The total number of runs the opposing team scored while the pitcher was in the game.

Earned Runs (ER)

The total number of runs the opposing team scored as a result of the pitcher giving up a hit (as opposed to scoring after a fielding error).

Walks/Balls-On-Base (BB)

The number of times in a game that the pitcher threw four balls or hit a batter with a pitch, allowing the batter to reach first base.

Strike-Outs (SO or K)

The number of times in a game that the pitcher threw three strikes.

Home Runs (HR)

The number of times in a game that a batter hit a home run against the pitcher.

The following statistics always refer to a pitcher's performance over the entire season.

Saves (SV)

The number of times the pitcher for the winning team pitched to the end of the game.

Earned Run Average (ERA)

Earned run average (abbreviated as ERA) is one of the most standard and commonly used statistics to measure a pitcher's performance. ERA is the average number of earned runs a pitcher gives up, per nine innings pitched. It is calculated by dividing a pitcher's total number of earned runs by his total number of innings pitched; this quotient is then multiplied by nine: (Earned Runs / Innings Pitched) x9. ERA is always written as a decimal to the hundredths place.

An average ERA is between 4.00 and 4.50. What is typically considered to be a good ERA is below 3.99 or below.

Walks Plus Hits Per Innings Pitched (WHIP)

Walks plus hits per innings pitched (abbreviated as WHIP) is another commonly used pitching statistic, and it is used to determine a pitcher's ability to prevent batters from reaching base. It is calculated by adding the total number of hits the pitcher gave up and the total number of walks he gave up, then dividing the sum by the total number of innings he pitched: (Hits+Walks) / Innings Pitched.

REMEMBER: WHIP is always written as a decimal to the hundredths place.

An average WHIP is approximately 1.30. What is typically considered to be a good WHIP is 1.20 or below.
