A good WHIP in baseball is anything below 1.20, and a WHIP under 1.00 is elite. In the 2026 MLB season, the league-average WHIP sat around 1.30, so any pitcher who beats that number is keeping more runners off base than a typical big leaguer.
If you follow fantasy baseball, scout pitchers, or just like to understand the numbers on a broadcast, WHIP is one of the most useful stats to know. It is simple to calculate and tells you a lot about how much traffic a pitcher allows.
What Does WHIP Mean in Baseball?
WHIP stands for Walks plus Hits per Inning Pitched. It measures how many baserunners a pitcher allows, on average, in each inning they throw.
The logic is simple: runners on base lead to runs. A pitcher who rarely lets batters reach base gives the opponent fewer chances to score. That is why WHIP has become a standard pitching stat on scoreboards, in fantasy leagues, and in front-office reports.
The stat was created in 1979 by writer Daniel Okrent, who also helped invent rotisserie (fantasy) baseball. He originally called it “innings pitched ratio.” The idea caught on, and today WHIP is one of the five standard pitching categories in most roto fantasy leagues, alongside wins, strikeouts, saves, and ERA.
Note what WHIP does not include. Batters who reach on errors, hit by pitches, or fielder’s choices are left out. Only walks and hits count.
How to Calculate WHIP
The WHIP formula adds walks and hits, then divides by innings pitched.
WHIP = (Walks + Hits) ÷ Innings Pitched
Example: A starting pitcher throws 180 innings in a season. He allows 150 hits and 45 walks.
- Add walks and hits: 150 + 45 = 195
- Divide by innings: 195 ÷ 180 = 1.083
- Round to two decimals: 1.08 WHIP
That pitcher allowed just over one baserunner per inning, which is an excellent season.
One detail trips people up: partial innings. In box scores, “6.1” innings means 6⅓ innings, and “6.2” means 6⅔. Convert those to thirds (6.333 or 6.667) before you divide, or your WHIP will be slightly off.
What Is a Good WHIP? The Benchmarks
In MLB, a WHIP of 1.20 or lower is good, 1.10 or lower is great, and 1.00 or lower is elite. Lower is always better, because it means fewer baserunners. Here is a general scale used by analysts and fantasy players:
WHIP | Rating | What it means |
|---|---|---|
1.00 or lower | Elite | Ace or lockdown closer; about one runner per inning |
1.01 – 1.10 | Great | Top-of-rotation starter |
1.11 – 1.20 | Above average | Solid, reliable pitcher |
1.21 – 1.30 | Average | Typical MLB pitcher |
1.31 – 1.40 | Below average | Allows too much traffic |
1.41 – 1.50 | Poor | Struggles to stay in games |
1.51+ | Very poor | At risk of losing a roster spot |
To put that in perspective, a 1.30 WHIP means about 12 baserunners over a nine-inning game. A 1.00 WHIP cuts that to nine. Three fewer runners a game adds up to many runs saved over a full season.
These ranges shift slightly from year to year with the run environment. When offense rises league-wide, the average WHIP climbs, and the bar for “good” moves with it.
League-Average WHIP and the Record Books
The MLB league-average WHIP in 2026 was about 1.30. According to StatMuse’s 2026 league splits, National League pitchers posted a 1.31 WHIP and American League pitchers a 1.30 during the regular season. That lines up with recent years, when the average has hovered between roughly 1.25 and 1.32.
The all-time marks show how rare a sub-1.00 WHIP really is:
- Single season (modern era): Pedro Martinez posted a 0.737 WHIP for the Boston Red Sox in 2000, widely considered one of the greatest pitching seasons ever.
- Career: Addie Joss, who pitched in the early 1900s, holds the career record at about 0.968.
- Modern aces: Pitchers such as Clayton Kershaw, Jacob deGrom, and Justin Verlander have strung together seasons under 1.00 at their peaks.
If a pitcher finishes a full season below 1.00, they are usually in the Cy Young conversation.
Good WHIP for Starters, Relievers, and Other Levels
Relievers are held to a slightly stricter WHIP standard than starters. A reliever pitches one inning at a time, often at maximum effort, and does not face the same lineup three times. Elite closers regularly post WHIPs under 1.00, while a reliever above 1.30 may lose high-leverage work.
Starters face more batters and tire late in games, so a WHIP between 1.10 and 1.20 over 170+ innings is very strong.
WHIP expectations also change by level:
- Minor leagues: Similar to MLB, though WHIPs run a little higher at lower levels where control is still developing.
- College baseball: Offense is higher, especially with metal bats, so a WHIP around 1.30 can be solid and under 1.20 is very good.
- High school: Walks are more common, and defenses make more errors. A WHIP under 1.20 is strong, and anything near 1.00 marks a standout arm.
- Youth baseball: WHIP is less meaningful here. Focus on throwing strikes rather than the number.
The Limitations of WHIP
WHIP is useful, but it treats every baserunner the same. A walk and a home run each add one to the total, even though the home run is far more damaging. Keep these blind spots in mind:
- No power context. A pitcher with a low WHIP can still give up lots of home runs.
- Defense and luck matter. Hits depend partly on the fielders behind the pitcher and on where balls happen to land (measured by BABIP).
- Hit batters are ignored. A pitcher who hits many batters looks better by WHIP than they really are.
- Small samples mislead. A reliever’s WHIP over 20 innings can swing wildly with one bad outing.
For a fuller picture, pair WHIP with related stats:
- ERA: Earned runs allowed per nine innings.
- FIP: Fielding Independent Pitching, which focuses on strikeouts, walks, and home runs.
- K/BB ratio: Strikeouts per walk, a strong sign of command.
- Opponent batting average (OBA): How often batters get hits.
How Pitchers Can Lower Their WHIP
The fastest way to lower WHIP is to cut walks. Walks are the part of the stat a pitcher controls most directly. Practical ways to improve:
- Win the first pitch. Getting ahead 0–1 sharply lowers the odds of a walk and puts hitters on the defensive.
- Command the fastball. Locating the fastball in the zone sets up every other pitch.
- Develop a put-away pitch. A reliable slider, curveball, or changeup earns strikeouts, which remove hitters without contact.
- Induce weak contact. Pitching to the edges and changing speeds leads to soft grounders and pop-ups instead of line drives.
- Stay efficient. Lower pitch counts keep pitchers fresher late in games, when WHIP often climbs.
For coaches, tracking walk rate and first-pitch strike percentage alongside WHIP shows exactly where a pitcher needs work.
Conclusion: What Is a Good WHIP in Baseball?
A good WHIP is 1.20 or lower, a great one is 1.10 or lower, and an elite one is 1.00 or lower. With the 2026 MLB average near 1.30, any pitcher below that mark is limiting traffic better than most of the league.
WHIP is quick to calculate and easy to compare, which makes it a go-to stat for fans, coaches, and fantasy managers. Just remember that it treats every baserunner equally. Pair it with ERA, FIP, and strikeout-to-walk ratio, and you will have a clear read on how good a pitcher really is.
