What is Barrel Rate? Definition, Formula, and Example
A barrel is a batted ball hit at 98+ mph exit velocity with a launch angle in a specific run-productive window — a combination that has historically produced a .500+ batting average and 1.500+ slugging. Barrel rate is the share of a hitter's batted balls that qualify. It is the single best predictor of sustainable power.

What Is a Barrel?
A barrel is Statcast's flagship batted-ball classification. MLB defines it as any ball in play hit at ≥98 mph with a launch angle in a narrow window that widens as exit velocity increases. At exactly 98 mph, the window is 26°–30°. At 100 mph, it's 24°–33°. By 116 mph, virtually any launch angle between 8° and 50° qualifies.
See the 2026 MLB Barrel Rate Leaders for the current live ranking from real Statcast data.
Why this window? Because balls hit inside it — league-wide, over millions of batted balls — have produced a minimum .500 batting average and 1.500 slugging percentage. Those are the thresholds MLB chose: a barrel is the class of contact that, empirically, behaves like a lock to produce extra-base hits or home runs.
Barrel Rate Formula
Barrel% (per PA) = Barrels / Plate Appearances
Barrel% (per BBE) = Barrels / Batted Ball Events
The per-BBE version is more common because it isolates quality of contact from strikeout/walk rates. Front offices watch both.
Worked Example
A hitter with 600 plate appearances and 400 batted balls produces 52 barrels.
- Barrel% per PA = 52 / 600 = 8.7%
- Barrel% per BBE = 52 / 400 = 13.0%
For context, 2024 MLB percentiles:
| Barrel% per BBE | Percentile | Interpretation |
|---|---|---|
| 4.3% | 50th | League average |
| 8.4% | 75th | Above average |
| 12.7% | 90th | Elite |
| 18.5% | 99th | Generational (Judge, Stanton, Ohtani) |
A 13.0% barrel rate puts this hitter in the top 10% of MLB. That translates to roughly 35–45 home runs over a full season assuming normal playing time and a neutral park.
Why Barrel Rate Matters
Two reasons barrel rate has become the premier power metric:
Predictive stability. Home run totals fluctuate wildly year to year based on ballpark, weather, and luck. Barrel rate is far more stable because it measures the underlying *quality* of contact rather than the binary home-run-or-not outcome. A 12% barrel-rate hitter in a tough park will still be a 12% barrel-rate hitter the next year — but his homer total might swing 30% either direction.
Early signal. Barrel rate stabilizes in roughly 50 batted balls — about two weeks of regular playing time. Home run rate takes two months. Sharp front offices and sharp fantasy players use this gap constantly: a hitter with 3 homers in April but a top-15 barrel rate is a buy-high signal, not a fluke.
Barrel Rate in Legends Deck
The "Power" attribute on every Legends Deck card is directly driven by real Barrel% per BBE. A card with 95 Power in-game maps to the 95th percentile of real MLB barrel rates. This is why you'll occasionally see power ratings that surprise you — a hitter who only hit 22 real-world home runs in 2025 might rate 90+ power if his barrel rate was elite but he played in a cavernous park.
Common Misconceptions
A barrel is not the same as "hard hit." Hard-hit means ≥95 mph EV regardless of angle. A line drive at 110 mph that's caught at the wall is hard-hit but not a barrel unless the angle falls in the window.
High exit velocity alone is not enough. Giancarlo Stanton has the highest average exit velocity in MLB, but in a given season his barrel rate can trail hitters with lower EV because ground balls — even at 120 mph — are never barrels. Launch angle matters just as much as velocity.
Frequently Asked Questions
What is a good barrel rate in MLB?
A good barrel rate is anything above about 10% on a per-batted-ball-event basis; league average sits around 6–8%, above-average is roughly the 75th percentile near 8.4%, and elite power hitters clear 12%. The generational tier (Judge, Stanton, Ohtani) reaches 18%+.
How is barrel rate calculated?
Barrel rate is the number of barrels divided by either plate appearances or batted-ball events, then multiplied by 100. The per-batted-ball-event version is most common because it isolates contact quality from strikeout and walk rates. A barrel itself requires at least 98 mph exit velocity paired with a launch angle in the window that widens as velocity rises.

Is barrel rate better than home run total for evaluating power?
Yes, barrel rate is generally a better forward-looking power indicator than raw home run totals because it measures the underlying quality of contact rather than the binary home-run outcome. It also stabilizes far faster — in roughly 50 batted balls versus about two months for home run rate — so it surfaces real power earlier and is less distorted by ballpark and weather.
