IP/GS Calculator
Definition – What is IP/GS?
IP/GS shows the average number of innings pitched for each game start that a pitcher has.
While a pitcher does not always have control over how long they are in the game for, it is an indicator of starting pitcher ability and stamina.
IP/GS is presented as is presented as a number with a decimal. A 1 or 2 after the decimal means 1/10th or 2/10ths of an inning. It does not mean 1 and 2 outs pitched (as some inning statistics are).
Formula – How to calculate IP/GS
IP/GS = (Innings Pitched + (Outs (Partial Innings) Pitched)) ÷ Game Starts
Example
If a pitcher has started 32 games, and in that time has pitched 202 innings and 1 out, then:
IP/GS = (202 + (1/3)) ÷ 32
IP/GS = 202.333333 ÷ 32
IP/GS = 6.32
This pitcher’s IP/GS is 6.32 – they have averaged about 6 1/3 innings (or 6 innings and 1 out) for each game they have started.
