ERA Rating Guide: Interpreting Earned Run Average Values

Understanding Your ERA Result

Your ERA (Earned Run Average) is one of the most telling numbers in baseball. It shows how many earned runs a pitcher allows per nine innings, giving you a clear measure of effectiveness. But what does a specific ERA number actually mean? This guide breaks down different ERA ranges, from elite to struggling, and explains what each implies for pitcher performance and what steps you can take to improve. For a refresher on the basics, check out our What Is ERA in Baseball? page.

The ERA Rating Scale

ERA values are typically grouped into ranges, each with a descriptive rating. The table below shows the commonly accepted scale for starting pitchers. Relief pitchers often have slightly different benchmarks due to shorter outings; see our ERA for Relief Pitchers guide for more details.

These ranges assume a starting pitcher with a reasonable number of innings. For relief pitchers, the same numbers may be interpreted differently; a reliever with a 4.50 ERA might be considered average, while a starter would be below average.

What Each Range Implies

Elite (Under 2.00)

An ERA under 2.00 is extremely rare and indicates a historic season. Pitchers at this level dominate hitters, missing bats and inducing weak contact consistently. If you see an ERA in this range, you’re looking at a potential Cy Young winner. What to do: Keep doing what you’re doing—your pitching mechanics, game plan, and execution are top-notch.

Excellent (2.00–3.00)

This range is still elite and often represents an All-Star. The pitcher allows very few runs and usually keeps the team in the game every start. What to do: Focus on maintaining consistency and avoiding any significant mechanical breakdowns.

Good (3.00–4.00)

A solid starting pitcher with good command and the ability to work out of jams. This is the sweet spot for a reliable rotation arm. What to do: Work on pitch sequencing and improving your secondary pitches to push into the excellent range.

Average (4.00–5.00)

This is around the league average. A pitcher at this level can still be effective but may have trouble in high-leverage situations. What to do: Analyze what’s causing runs—whether it’s walks, home runs, or weak contact. Adjust your approach accordingly. If you need help calculating your ERA, see our How to Calculate ERA guide.

Below Average (5.00–6.00)

Pitchers in this range often struggle with command or get hit hard. They may not last long as starters unless they show improvement. What to do: Focus on reducing walks and lowering the number of hard-hit balls. Consider mechanical adjustments or a role change (e.g., moving to the bullpen).

Poor (6.00–7.00)

This ERA indicates severe struggles. The pitcher is likely allowing multiple runs per inning and may be a liability. What to do: Consider a complete overhaul of approach, mechanics, or even a change in the type of pitches thrown. Seeking coaching or video analysis is recommended.

Terrible (Over 7.00)

An ERA above 7.00 is unsustainable. The pitcher is getting hit extremely hard and/or walking many batters. What to do: A fundamental revisit of pitching fundamentals is necessary. The pitcher may need to work on all aspects of their game, from mechanics to mental approach.

Factors That Affect ERA Interpretation

ERA doesn’t tell the whole story. Ballpark factors, defense quality, and league average can all influence interpretation. For example, a 4.00 ERA in Coors Field (high altitude) is much better than a 4.00 ERA in Petco Park (pitcher-friendly). Also, the era of baseball matters—historical averages have changed over time.

Using This Guide

After calculating a pitcher’s ERA with our ERA Calculator, compare the result to the table above. Keep in mind that ERA is a cumulative statistic and can fluctuate over a season. A small sample size (e.g., less than 30 innings) can produce misleading extremes. Always consider innings pitched when judging reliability.
