What's a Good Whiff Rate in MLB? 2026
The MLB league-average whiff rate in 2026 is roughly 25%, an elite pitcher clears 30%, and the best swing-and-miss arms in baseball top 40%. Here's what counts as a good whiff rate, the league baseline, how whiff rate differs from swinging-strike rate, and who leads MLB right now.

What is a good whiff rate in MLB?
The MLB league-average whiff rate in 2026 is roughly 25% — meaning hitters miss about a quarter of the swings they take against a typical pitcher. A good whiff rate clears 30%, an elite one clears 35%, and the small group of best swing-and-miss arms in baseball tops 40%. The current leaders on the 2026 MLB whiff rate leaderboard are in that 40%+ tier, well above the league baseline. See all MLB Statcast leaderboards →
So the quick mental model: 25% is average, 30% is good, 35% is excellent, and 40%+ is the rarefied air where the league's nastiest relievers and a handful of starters live.
What counts as a good whiff rate, tier by tier?
Whiff rate maps cleanly onto pitcher tiers because it isolates pure stuff — how often a pitch misses a bat once a hitter commits to swinging:
- Elite (35%+): the top of the leaderboard. Overpowering stuff that hitters can't catch up to even when they're geared up to swing. Mostly high-velocity relievers and the rare front-line starter.
- Above average (30-34%): clear swing-and-miss weapon. A pitcher here misses bats well above the league rate and almost always carries a strong strikeout rate.
- League average (~25%): the baseline. A pitcher here gets a typical number of whiffs and likely relies on command, contact management, or pitch sequencing for value rather than pure miss-bats stuff.
- Below average (under 22%): contact-oriented profile. These pitchers survive on weak contact, ground balls, and limiting walks rather than racking up swings-and-misses.
The tiers shift slightly by pitch type — sliders and splitters naturally run higher whiff rates than fastballs and sinkers — but the overall-arsenal numbers above are the ones quoted on a pitcher's Statcast page and on the leaderboard.
Whiff rate vs. swinging-strike rate vs. strikeout rate
These three get used interchangeably, but they measure different things, and the denominators are what separate them:
- Whiff rate = swings-and-misses divided by total swings. It answers: when a hitter swings, how often do they miss? This is the cleanest read on pure stuff because it controls for whether hitters chase.
- Swinging-strike rate (SwStr%) = whiffs divided by total pitches. A pitcher who can't get hitters to swing at all will post a low SwStr% even with elite stuff, because the denominator includes every take.
- Strikeout rate (K%) = the percentage of plate appearances ending in a strikeout. It's downstream of whiff rate plus called strikes plus the ability to finish two-strike counts — so a high whiff rate doesn't automatically produce a high K%.
Because whiff rate divides only by swings, it's the metric most analysts now treat as the truest measure of pitch quality. A "good whiff rate" of 30%+ is a far stronger signal of dominant stuff than a strikeout total, which inflates with innings load.

Why a good whiff rate matters more than strikeout totals
Strikeout totals are a counting stat — they grow with innings, role, and opponent quality. Whiff rate is a rate stat that isolates how often the stuff actually misses, and it stabilizes fast: roughly 100 pitches, about 4-5 outings for a reliever. That's quicker than nearly any other pitching metric.
That speed is why front offices watch whiff rate as the leading signal on bullpen acquisitions. A pitcher with a 35% whiff rate but a modest strikeout total is usually a breakout waiting to happen — the swing-and-miss is real, and the strikeouts follow once command or sequencing catches up. A pitcher with a good strikeout total but a below-average whiff rate is the warning sign: the results are outrunning the stuff. Pair whiff rate with fastball velocity to separate the pure-power arms from the pitchers who miss bats on movement and deception.

How does whiff rate translate to Legends Deck card ratings?
The pitcher card ratings on Legends Deck pull from a combination of fastball velocity, whiff rate, command, and pitch-mix breadth, refreshed nightly from real Statcast data. A whiff rate well above the ~25% league baseline maps to elite stuff scores; combined with command, it produces a top-tier overall pitcher card. A below-average whiff rate maps to a contact-management profile instead.
In PvP and Franchise Mode the simulation engine uses pitcher whiff rate as a direct input to per-pitch outcomes — a higher whiff rate yields a higher swing-and-miss probability on any given swing.
