The Impact of Pitch Call Rating


Purpose:
To determine if a catchers pitch call rating impacts a teams era.

Procedures:
To be included in the list a team needed to have 2 catchers who caught for at least 300 innings. The catchers had to have a difference in their pitch call rating of 10 or greater. If a team used more than 3 catchers during the season the catchers with the best and worst pitch call rating were used to determine the effect on the teams era. Essentially the middle catcher was ignored. The stats are based on season 9. No teams were left out intentionally I just got tired of doing it.

The first number after the catchers name is the pitch call rating, the second is the number of innings they caught, and the third is the team era.

Conclusion:
There appears to be some correlation between a catchers pitch call rating and the teams era. Generally a teams era improved when using a catcher with a higher pitch call rating. Obviously there are numerous variables that were not taken into account.

Results:
Of the 15 teams 6 teams experienced significant improvement (.50 improvement or greater) in the teams era when using a catcher with a better pitch call rating.
Of the 15 teams 5 teams experienced marginal improvement in the teams era (.01 to .49) in the teams era when using a catcher with a better pitch call rating.
Of the 15 teams 4 teams experienced marginal worsening in the teams era (.01 to .49) in the teams era when using a catcher with a better pitch call rating.
No teams experienced a significantly worse team era when using a catcher with a better pitch call rating.
