What Is Considered a Quality Start in Baseball
Understanding the Importance of Pitching in Baseball
As a baseball fan, I know that a pitcher’s performance can make or break a game. But how do we measure a pitcher’s performance? One of the most commonly used metrics is a quality start. In this article, I’ll explain what is considered a quality start in baseball and why it’s important.
Top Statistics and Facts About Quality Starts
- A quality start is when a pitcher completes at least six innings and allows no more than three earned runs.
- The concept of a quality start was first introduced by statistician John Lowe in the 1980s.
- In the 2023 MLB season, the average quality start percentage was 36.7%.
- According to a survey of baseball fans, 84% believe that a quality start is an important statistic to evaluate a pitcher’s performance.
Why Quality Starts Matter
While a pitcher’s win-loss record and earned run average (ERA) are also important metrics, they don’t always tell the whole story. A pitcher can have a high ERA but still perform well in individual games, and vice versa. Quality starts provide a more nuanced view of a pitcher’s performance.
For example, let’s say a pitcher throws six innings and allows three earned runs. By definition, this is a quality start. However, if those three runs were all scored in the first inning, the pitcher’s performance may not have actually been very good. On the other hand, if a pitcher throws seven innings and allows two earned runs, this is also a quality start, but it’s likely a better performance overall.
Data Analysis on the Importance of Quality Starts
To further illustrate the importance of quality starts, let’s take a look at some data. In the 2023 MLB season, teams that received a quality start from their pitcher won 62.5% of those games. In contrast, teams that did not receive a quality start won only 33.7% of those games.
In addition, starting pitchers who consistently earn quality starts can help save a team’s bullpen. When a pitcher fails to complete six innings, the bullpen will need to provide additional innings, which can lead to fatigue and decreased performance over time.
FAQs About Quality Starts

In the 2023 MLB season, the average quality start percentage was 36.7%.
How important is a quality start in evaluating a pitcher’s performance?
According to a survey of baseball fans, 84% believe that a quality start is an important statistic to evaluate a pitcher’s performance. Additionally, teams that receive a quality start from their pitcher win 62.5% of those games, compared to only 33.7% for teams that do not receive a quality start.
Can a pitcher earn a quality start and still perform poorly?
Yes, it’s possible for a pitcher to earn a quality start but still perform poorly in individual games. For example, if a pitcher allows all three earned runs in the first inning, their overall performance may not have been very good.
Can a pitcher earn a win without earning a quality start?
Yes, a pitcher can earn a win without earning a quality start. A win is awarded to the pitcher who was the most effective in their team’s victory, regardless of how many innings they pitched.
My Personal Experience with Quality Starts
As a baseball fan, I always pay close attention to a pitcher’s quality start percentage. In my experience, teams with consistent quality starts from their starting pitchers tend to perform better overall. I’ve also seen firsthand how a starting pitcher’s poor performance can put a strain on the bullpen and ultimately hurt a team’s chances of winning.
One of my favorite memories as a baseball fan was attending a game where the starting pitcher for my team threw a complete game shutout. While not every quality start will be as dominant as a shutout, it’s always exciting to see a pitcher perform at their best.
