definition quality start

Date : 27-02-2023

In the context of baseball, a quality start is a statistic used to evaluate the performance of starting pitchers. A quality start occurs when a pitcher completes at least six innings in a game and allows no more than three earned runs. This means the pitcher has effectively kept their team in the game by limiting the opposition's scoring.

More specifically, to be considered a quality start, a starting pitcher must meet the following criteria:

  1. Pitch at least six innings
  2. Allow no more than three earned runs
  3. Have more strikeouts than walks

The quality start metric was introduced in 1985 by sportswriter John Lowe as a way to measure the effectiveness of starting pitchers. Since then, it has become a widely accepted statistic in the world of baseball.
