As a rough guide, an ERA under 3.00 is good and under 2.00 is excellent for a high school pitcher, while big leaguers as a group usually land around 4.00. At youth levels ERA swings wildly because of fielding errors, short games, and small samples, so it’s a weak measure of how well a young pitcher is actually throwing. Strike percentage, walks, and first-pitch strikes usually tell you more.
ERA is the first number most people look at when they talk about a pitcher. It’s simple, it’s on every stat sheet, and a low one sounds great. But for young pitchers, ERA can be one of the most misleading numbers in baseball, and judging a kid by it can steer his development the wrong way.
Here is what ERA measures, what a good ERA looks like at different levels, and what to pay more attention to.
What ERA measures
ERA (earned run average) is how many earned runs a pitcher gives up per full game. Earned runs are runs that scored without the help of errors. Because high school games are usually seven innings and many youth games are six, ERA at those levels is often calculated on that shorter game length. Our free ERA calculator does the math for any game length, along with WHIP and strike percentage.
Rough benchmarks by level
| Level | A rough sense of good |
|---|---|
| Youth | Too noisy to judge on ERA alone |
| High school | Under 3.00 good, under 2.00 excellent |
| College | Varies a lot by level and conference |
| MLB | Around 4.00 is roughly average |
These are rules of thumb, not official standards. A pitcher in a strong conference with tough hitters can be excellent with a higher ERA than a pitcher in a weaker league.
“ERA tells you what happened. Strike percentage tells you how well he pitched.”
Judge the process, not just the scoreboard.Why ERA misleads at young ages
Defense decides a lot
Youth fielding is unpredictable. Scorekeepers don’t always charge errors consistently, so plenty of “earned” runs aren’t really on the pitcher.
Tiny samples
A young pitcher might throw 20 innings in a season. One bad inning can double his ERA.
It hides good habits
A kid who attacks the zone may give up some hits and runs while building exactly the habits that pay off later.
What to watch instead
- Strike percentage. The best single number for a young pitcher. Our guide on a good strike percentage has the benchmarks.
- Walks. Free bases are the clearest sign of command trouble. Our guide on why he walks so many batters covers the fixes.
- First-pitch strikes. Getting ahead changes everything, as our guide on first-pitch strikes explains.
And compare him to himself, not to the kid on Instagram or the ace on the other team. A pitcher whose strike percentage rises and walks drop over a season is improving, whatever his ERA says.
Those numbers all come back to a delivery that repeats. A free evaluation breaks his mechanics down frame by frame and shows what’s helping or hurting his command. Start his free evaluation.
The bottom line
For a high school pitcher, an ERA under 3.00 is generally good and under 2.00 is excellent, while big leaguers average around 4.00. At youth levels, ERA swings so much with defense and small samples that it says little about how well a kid is pitching. Track strike percentage, walks, and first-pitch strikes instead, and judge his progress over a season.
Common questions
What is a good ERA for a high school pitcher?
As a rough guide, under 3.00 is good and under 2.00 is excellent, though it depends on the level of competition. High school ERA is usually based on seven-inning games.
What is a good ERA for a youth pitcher?
There isn’t a meaningful benchmark at most youth levels, because fielding errors, short games, and small numbers of innings make ERA swing wildly. Strike percentage, walks, and first-pitch strikes are better measures.
What is the average ERA in MLB?
Big league pitchers as a group usually land somewhere around 4.00, give or take depending on the season.
Is ERA a good stat for young pitchers?
Not on its own. It depends heavily on defense and luck, and young pitchers throw too few innings for it to settle. It’s better to track whether he’s throwing strikes, limiting walks, and getting ahead of hitters.
