TL;DR: A good ERA in baseball ranges from 2.50 to 4.00. In modern MLB, the league average sits between 4.00 and 4.50, so anything below 4.00 is above average. Elite pitchers post ERAs below 2.50, while youth and amateur players should compare numbers against their own level, not professional standards.
What Is a Good ERA in Modern Baseball?
A good ERA in baseball is anything below 4.00, since the modern MLB average falls between 4.00 and 4.50. Earned Run Average measures how many earned runs a pitcher allows per nine innings pitched, making it baseball’s primary pitching statistic. Anything well below the 4.00 to 4.50 range signals above-average performance. Numbers above that range suggest a pitcher needs improvement. Context always matters when reading ERA, but this benchmark gives you a reliable starting point.
What Are the ERA Benchmarks for Professional Pitchers?
In MLB, ERA performance falls into four clear tiers: elite (below 2.50), very good (2.50 to 3.25), solid (3.25 to 4.00), and below average (above 4.50). Pitchers with ERAs above 4.50 typically struggle to hold rotation spots on competitive teams. Elite pitchers who consistently post ERAs below 2.50 enter Cy Young Award and All-Star conversations. For full detail on how these numbers get calculated, see the How to Calculate ERA in Baseball: Complete Guide.
| ERA Range | Performance Tier | What It Means |
|---|---|---|
| Below 2.50 | Elite | Cy Young contender, All-Star level |
| 2.50 to 3.25 | Very Good | Clear rotation anchor, high trade value |
| 3.25 to 4.00 | Solid | Reliable starter or setup reliever |
| 4.00 to 4.50 | League Average | MLB baseline in recent seasons |
| Above 4.50 | Below Average | Rotation spot at risk on competitive teams |
What Is a Good ERA for Starters vs. Relievers?
Relief pitchers generally carry lower ERAs than starters because they pitch fewer innings, face fewer batters per outing, and enter games in favorable matchup situations. Starting pitchers face batters multiple times through the order and pitch deeper into games, so a 3.50 to 4.00 ERA is more acceptable for a starter than for a closer. Quality starters who consistently post ERAs below 3.75 provide strong value to their teams. Elite starters who stay under 3.00 become franchise cornerstones. Closers and setup men who approach 4.00 face more scrutiny because of the shorter, higher-stakes nature of their appearances. Middle relievers and long relievers often post the highest ERAs among bullpen arms since they enter in less favorable situations.
What Factors Affect Whether an ERA Is Good?
Ballpark dimensions, defensive quality, and league offensive environment all shape what a good ERA looks like in any given season. Pitcher-friendly stadiums with larger foul territory and deeper outfield walls suppress run scoring, while hitter-friendly parks inflate it. Denver’s Coors Field can inflate ERAs by 15 to 20 percent compared to pitcher-friendly venues. Defensive support matters too, since skilled fielders and smart positioning, including strong baseball shortstop positioning, directly reduce earned run totals. Weather, altitude, and humidity also affect ball flight and pitcher grip. Modern baseball hitting technology has helped hitters identify and attack pitching patterns more effectively, which pushes average ERAs upward across the league.
How Does a Good ERA Change Across Leagues and Levels?
ERA expectations shift significantly depending on the competitive level, so you should always compare a pitcher’s ERA to others at the same level. College ERAs typically run 0.50 to 1.00 higher than professional levels due to aluminum bat usage and developing pitching skills. High school baseball sees even higher averages, with good performance often landing in the 3.00 to 5.00 range depending on regional competition. For young players, pairing ERA awareness with smart high school baseball equipment choices helps development at every stage. Japan’s NPB maintains ERAs closer to MLB standards, while independent leagues can show inflated numbers. Youth baseball ERAs can swing wildly due to small sample sizes, varying skill levels, and shorter game formats.
How Has a Good ERA Changed Throughout Baseball History?
ERA standards have shifted with each offensive era, so historical comparisons require context. During the dead ball era from 1900 to 1919, league-wide ERAs often stayed below 3.00. The steroid era in the 1990s and 2000s pushed average ERAs above 4.50 as offense spiked. By 2014, the league-wide ERA dropped to its lowest point since the 1980s. Modern rule changes around mound visits, pitcher usage, and defensive shifts continue reshaping what excellent pitching looks like in 2026. A 3.20 ERA might have been merely good in one decade and exceptional in another, which is why era context matters when evaluating any pitcher’s numbers.
Is a 1.47 ERA Good?
Yes, a 1.47 ERA is exceptional by any standard in baseball. At the MLB level, an ERA that low places a pitcher among the very best in the league for that season and puts them in strong Cy Young Award contention. ERAs below 2.00 are rare even for elite starters. A 1.47 ERA signals dominant run prevention, outstanding command, or both. At lower levels such as high school or college, a 1.47 ERA is still outstanding, though small sample sizes can make such numbers less stable over a short stretch of games. Whether you see this number in professional or amateur baseball, it represents pitching performance that is far above average.
Is a 15 ERA Good?
No, a 15 ERA is not good at any level of baseball. An ERA of 15 means a pitcher is allowing 15 earned runs per nine innings, which is well above even the highest league averages in amateur play. In MLB, even struggling pitchers rarely sustain ERAs above 6.00 before roster changes are made. A 15 ERA most often appears in very small sample sizes, such as one or two outings early in a season, where a single bad game can create a misleading number. If a pitcher has thrown only three innings and allowed five earned runs, their ERA may sit at 15 but tells you almost nothing reliable about true ability. As the sample size grows, the ERA will stabilize and become a more accurate reflection of performance. Coaches applying modern youth baseball coaching techniques should focus on mechanical improvement and sample size context rather than reacting to a single high ERA early in the year.
What Is a Good ERA for Youth Baseball Players?
Youth baseball players should focus on improvement trends rather than matching professional ERA benchmarks, since smaller sample sizes and varying skill levels make direct comparisons unreliable. Good ERA ranges in youth leagues are naturally higher than in professional play due to developing mechanics, shorter games, and inconsistent competition. Coaches and parents should treat ERA as one data point among many. Working on fundamental mechanics through proven tee drills for proper head position often delivers more long-term value than chasing a specific ERA target. Teams on tight budgets can also support pitcher and hitter development with tools like portable batting cages for high school programs, which build the overall environment that helps pitchers improve.
What Stats Should You Use Alongside ERA?
WHIP, strikeout rates, walk rates, and FIP give you a fuller picture of pitching performance when used alongside ERA. ERA can be artificially low if a pitcher benefits from strong defensive support, a favorable ballpark, or a small sample size. It can also look worse than deserved if fielders struggle behind a pitcher. WHIP tracks baserunners allowed per inning and reveals command issues that ERA might hide. Strikeout and walk rates show how a pitcher controls at-bats independent of what happens after contact. FIP, or Fielding Independent Pitching, estimates ERA based only on outcomes the pitcher controls directly. Using these metrics together gives coaches, scouts, and fans a much more complete and honest view of pitching effectiveness.

Frequently Asked Questions
What ERA makes a pitcher above average in MLB?
Any ERA below 4.00 is above average in modern MLB, where the league average typically falls between 4.00 and 4.50. Pitchers in the 3.25 to 3.75 range are considered solid contributors to competitive rosters.
What is considered an elite ERA in professional baseball?
Elite pitchers consistently post ERAs below 2.50, placing them among league leaders and Cy Young Award candidates. ERAs under 2.00 are exceptionally rare and indicate a dominant season-long performance.
How does ERA differ between starters and relievers?
Relief pitchers generally maintain lower ERAs than starters because they pitch fewer innings, face fewer batters per appearance, and often enter games in situations that favor their success. A 3.50 ERA is more acceptable for a starting pitcher than for a closer.
Do ERA standards change based on the offensive environment?
Yes. High-offense eras make a 4.50 ERA more acceptable, while pitcher-friendly periods make sub-3.00 ERAs more achievable for top performers. Ballpark factors and rule changes in 2026 continue to shape what counts as a good ERA each season.
Is a 1.47 ERA good in baseball?
Yes, a 1.47 ERA is exceptional at any level. In MLB it places a pitcher among the season’s best and puts them in Cy Young contention. Even in youth or college baseball, a 1.47 ERA represents outstanding run prevention.
Is a 15 ERA good in baseball?
No, a 15 ERA is not good. It most often appears after only one or two rough outings when the sample size is too small to be meaningful. As a pitcher throws more innings, the ERA will stabilize into a more accurate reflection of true performance.
What stats should I use alongside ERA to evaluate a pitcher?
WHIP, strikeout rate, walk rate, and FIP all add important context to ERA. These metrics help you identify whether a low ERA reflects true skill or just strong defensive support and favorable circumstances.
