What is “save percentage”?

Save Percentage is a baseball statistic used to put a relief pitcher’s number of saves in comparison with the number of times they have had an opportunity to save.

It is intended to be used along with the pitcher’s ERA (earned run average), wins, total number of saves, and other statistics to evaluate the pitcher’s performance.

Save percentage is helpful as statistics such as ERA can be skewed if the relief pitcher inherits a number of runners on base, and statistics such as pure pitching performance do not take into the pitcher’s long term win/loss results.

How to calculate Save Percentage in Baseball

In Baseball, save percentage is calculated as follows:

Save Percentage = Saves / Save Opportunities


If a relief pitcher has had 27 save opportunities and made 22 saves, then:

22 divided by 27 is divided by 127 is 0.815.

0.815 converted to a percentage is 81.5%.

Therefore, the relief pitcher’s save percentage is 81.5%

What counts as a “save”?

A save happens when a relief pitcher

1. Is the finishing pitcher in a game won by his team

2. Is not the winning pitcher (the pitcher who receives the “win” for the game, usually the starting pitcher)

3. Is credited with at least 1/3 of an inning pitched and

4. Enters the game with a lead of no more than three runs and pitches for at least one inning OR Enters the game, regardless of the count, with the potential tying run either on base, at bat, or on deck OR Pitches for at least 3 innings.

What counts as a “Save Opportunity”?

A save opportunity is when a relief pitcher enters a game in a situation that permits the pitcher to earn a save.
