QAB in Baseball — What It Is, How It's Scored & What's Good
QAB stands for Quality At Bat — an unofficial stat that measures whether a hitter helped the team during a plate appearance, regardless of whether they got a hit.Quick Answer
QAB = Quality At Bat. A good QAB percentage is 55–65%.
A QAB is any plate appearance where the hitter helped the team — through a hit, walk, hard-hit ball, moving a runner, driving in a run, or working the count. It's calculated as QABs divided by total plate appearances. Elite is 60%+, average is 50–59%, below 50% needs work.
When I was playing baseball as a kid the stats were simple — batting average, RBIs, and how many strikeouts you had. QAB wasn't part of the conversation. Now it's one of the most common metrics I hear coaches use at the travel ball level, and for good reason. It tells a story about a player's at-bats that batting average completely misses.
A kid who goes 1-for-4 with three 10-pitch at-bats that ran the opposing pitcher's count up might have a better game than the kid who went 2-for-4 on the first pitch both times. Batting average says the second kid had a better day. QAB tells the real story.
What Does QAB Mean in Baseball?
QAB stands for Quality At Bat. It's an unofficial baseball stat — meaning it doesn't appear in official box scores or MLB stat sheets — that measures whether a batter's plate appearance contributed positively to the team, regardless of whether it resulted in a hit.
Unlike ERA or batting average, QAB is somewhat subjective. Different coaches and scorekeepers use slightly different criteria for what qualifies. But the most widely used framework includes 12 specific outcomes — and we've laid all of them out in the chart below.

How Is QAB Calculated?
The formula is straightforward:
QAB% Formula
QAB% = (Number of Quality At Bats) ÷ (Total Plate Appearances)
Example: A player has 4 plate appearances in a game. Two of them result in a walk and a hard-hit single — 2 QABs out of 4 plate appearances = 50% QAB for that game.
One plate appearance can count as multiple QAB criteria — but it's still only counted as one QAB. A walk on a 9-pitch at-bat after going down 0-2 hits three different criteria (walk, 8+ pitches, 4 after 0-2) but the plate appearance counts as one quality at bat in the denominator.
What Is a Good QAB Percentage?
60%+
Elite
Consistently impacting the game every plate appearance. Coaches love these hitters.
50–59%
Above Average
Good approach at the plate. Most competitive players at the high school level land here.
Below 50%
Needs Work
Plate approach needs development. Focus on working counts and situational hitting.
QAB Benchmarks by Level
| Level | Average QAB% | Elite QAB% | Notes |
|---|---|---|---|
| Youth Rec (8U–10U) | 35–45% | 50%+ | Pitch recognition still developing — any contact or walk is a win |
| Travel Ball (10U–12U) | 40–50% | 55%+ | Count awareness starts to matter here |
| Travel Ball (13U–14U) | 45–55% | 60%+ | Hard-hit ball criteria becomes more meaningful at this velocity |
| High School JV | 48–55% | 62%+ | Situational hitting and count management expected |
| High School Varsity | 52–60% | 65%+ | Elite varsity hitters consistently above 60% |
| College / Adult | 55–62% | 68%+ | Plate discipline and situational awareness at highest level |
The target your coach is probably using
Most travel ball and high school coaches set the team QAB target at 60% of plate appearances, with a goal of 30–40% of those coming from hard-hit balls specifically. In practice most players hover around 50% QAB with 25–30% hard-hit. Getting a player from 45% to 55% in a season is meaningful progress and will show up in run production before it shows up in batting average.
Why QAB Matters More Than Batting Average for Young Players
Batting average is the stat most kids (and parents) fixate on — and it's the worst possible metric to use for player development at the youth level. Here's why:
The best hitters in MLB history got a hit roughly 3 times out of every 10 at-bats. A .300 batting average is elite at the professional level. Youth players who measure their entire self-worth by whether they got a hit in 4 plate appearances are going to feel like failures 70% of the time — because even elite hitters fail 70% of the time.
QAB changes that math. A player who went 0-for-4 but had three 8-pitch at-bats, drew a walk, and moved a runner into scoring position twice had an excellent day by QAB metrics. Their batting average says zero. Their contribution to the game was real and measurable.
How to use QAB in a post-game conversation with a young player
Instead of "you went 1-for-4 tonight" — try "you had 3 quality at bats out of 4 plate appearances, which is really strong. You worked the count, moved runners, and the pitcher had to throw a lot of pitches because of you." The pitcher's pitch count is directly affected by how well hitters execute quality at bats — a lineup full of QAB hitters gets to the opposing bullpen faster, which is a real competitive advantage.
QAB in Softball
The same QAB framework applies to softball with minor adjustments for the differences in pitching distance and game pace. The criteria are identical — hits, walks, hard-hit balls, moving runners, working the count. Benchmark percentages are similar at equivalent competitive levels. For softball coaches tracking QAB, the pitch-count criteria (8+ pitches, 4 after 0-2) are less commonly used at youth levels since pitching distances are shorter and at-bats tend to be shorter. The outcome-based criteria — hits, walks, RBIs, sacrifices — are the most universally applied in softball QAB tracking.

Frequently Asked Questions
What does QAB mean in baseball?
QAB stands for Quality At Bat — an unofficial stat that measures whether a plate appearance contributed positively to the team. It counts outcomes like hits, walks, hard-hit balls, sacrifice flies, moving runners into scoring position, and working long counts. Unlike batting average, a QAB can be earned even when the batter makes an out.
What is a good QAB percentage in baseball?
A QAB percentage of 60% or higher is considered elite. Between 50% and 59% is above average and represents solid plate discipline. Below 50% indicates the player's approach at the plate needs development. Most competitive high school players land between 50% and 60% over a full season.
What is a good QAB percentage for high school?
For high school baseball, a QAB% between 52% and 60% is solid. Elite high school hitters with excellent plate discipline can consistently hit 65% or above. JV players averaging 48–55% are on track. Most coaches set team targets at 60% and track individual progress toward that benchmark over the season.
How is QAB calculated?
QAB% = Number of Quality At Bats ÷ Total Plate Appearances. Count how many of a player's plate appearances meet at least one of the 12 QAB criteria, then divide by their total plate appearances. One plate appearance counts as one QAB regardless of how many criteria it meets.
How many pitches is a quality at bat?
An at-bat with 8 or more pitches automatically qualifies as a QAB regardless of outcome. Additionally, seeing 4 or more pitches after going down 0-2 in the count qualifies — this specifically rewards the ability to battle back from a tough count. Simply seeing 6 or 7 pitches without a strikeout doesn't automatically qualify under most frameworks.
Does a strikeout count as a QAB?
Generally no — a strikeout doesn't qualify as a QAB under any standard criteria. However, a 9-pitch strikeout where the batter went 0-2 and battled back to see 4 more pitches would qualify under the "4 after 0-2" criterion in some scoring systems. Most coaches don't give QAB credit for strikeouts regardless of pitch count.
Is QAB used in MLB?
QAB is not an official MLB statistic and doesn't appear in standard box scores. It's primarily used at the youth, high school, and college levels as a developmental coaching tool. Some MLB analytics departments track plate discipline metrics that overlap with QAB concepts — pitch counts per plate appearance, hard-hit rate, walk rate — but not QAB itself as a formal stat.
The bottom line
QAB is the most useful hitting metric for developing players — more useful than batting average at every level below the professional game. A 60% QAB target is achievable and meaningful. The chart above gives you every criterion, every abbreviation, and every benchmark you need to start tracking it tonight.
For young players especially: the goal at the plate isn't a hit. The goal is a quality at bat. Hits come when you stop chasing hits and start executing quality plate appearances. That mental shift — away from batting average and toward process — is one of the most impactful things a coach or parent can give a player.
