What is WHIP in Baseball?

If you want to know how effective a pitcher truly is, look at their WHIP. Standing for Walks and Hits Per Inning Pitched, WHIP is one of the most widely used sabermetric statistics in baseball and softball.

While Earned Run Average (ERA) tells you how many runs a pitcher gives up, WHIP tells you exactly how much "traffic" a pitcher allows on the basepaths. A lower WHIP means a pitcher is efficiently getting batters out without allowing them on base.

How to Calculate WHIP

Calculating WHIP is incredibly straightforward. You only need three numbers from a pitcher's box score: Walks (BB), Hits (H), and Innings Pitched (IP).

The WHIP Formula:

WHIP = {Walks + Hits}/{Innings Pitched}

The "Fractional Inning" Secret (How to Avoid Math Errors)

The number one mistake people make when calculating WHIP (and why standard calculators fail) revolves around Innings Pitched.

In baseball, there are 3 outs in an inning. Therefore:

• 0.1 Innings = 1 Out (Mathematically $1/3$, or $0.333$)
• 0.2 Innings = 2 Outs (Mathematically $2/3$, or $0.666$)

If a pitcher pitches 5 innings and gets 1 out in the 6th, their line reads 5.1 IP. If you type 5.1 into a standard calculator, your math will be wrong! Our WHIP calculator above features a "Smart Parser" that automatically converts .1 and .2 into the correct fractions for you.

Step-by-Step WHIP Calculation Example

Let’s calculate the WHIP for a starting pitcher who had the following game:

• Innings Pitched: 6.2 (6 innings, 2 outs = 6.666)
• Hits Allowed: 5
• Walks Allowed: 2

1. Add Walks and Hits: $5 + 2 = 7$ total baserunners.
2. Convert IP to decimal: $6.2$ becomes $6.666$.
3. Divide: $7 \div 6.666 = 1.05$

This pitcher has a WHIP of 1.05 for the game.

What is a Good WHIP in Baseball?

WHIP is heavily relied upon in fantasy baseball and MLB front offices. Here is the generally accepted scale for grading a pitcher's WHIP over a full season:

WHIP Range	Grade	Description
Below 1.00	Elite	Cy Young candidates; dominant aces.
1.00 – 1.15	Great	All-Star level pitchers.
1.16 – 1.30	Average	Reliable major league starters.
1.31 – 1.40	Below Average	Prone to giving up big innings.
Above 1.40	Poor	High risk of being demoted or pulled.

Common Mistakes When Calculating WHIP

1. Including Hit-By-Pitch (HBP): Despite the fact that hitting a batter puts them on base, HBPs are not included in the WHIP formula. (Though some advanced modern stats like OBP against do include them).
2. Including Errors (ROE): If a batter reaches base because the shortstop dropped the ball, it does not count against the pitcher's WHIP.

FAQ SECTION

1. How do you calculate the WHIP?

To calculate WHIP, add the pitcher's total Walks allowed and Hits allowed, and divide that sum by their total Innings Pitched.

2. Is a 1.50 WHIP good?

No, a 1.50 WHIP is considered poor for a Major League pitcher. It means the pitcher is allowing an average of one and a half baserunners every single inning, which frequently leads to giving up runs.

3. Is a .80 WHIP good?

Yes! A 0.80 WHIP is not just good; it is historic. Only the greatest pitchers in baseball history are capable of sustaining a WHIP under 1.00 for a full season.

4. Is a .500 WHIP good?

A 0.500 WHIP is statistically miraculous and essentially impossible to maintain over a full MLB season. However, a relief pitcher might maintain a 0.500 WHIP over a small sample size of a few games.

5. Who has the lowest WHIP in MLB history?

The record for the lowest career WHIP in MLB history belongs to Addie Joss (0.968). In modern baseball (the live-ball era), Pedro Martinez holds the single-season record with an astonishing 0.737 WHIP set in the year 2000.

6. What MLB pitcher has the best WHIP?

Among active pitchers with enough innings to qualify, Jacob deGrom consistently ranks at the top for the best career WHIP, hovering around the 0.99 territory.

7. What is the Ohtani rule?

The "Ohtani Rule" is a relatively new MLB rule stating that if a starting pitcher is also hitting in the lineup as the Designated Hitter (DH), they can remain in the game as the DH even after they are removed from the game as a pitcher. It was specifically designed for two-way superstar Shohei Ohtani.

8. What is the Maddux rule?

A "Maddux" is a baseball achievement, not a formal rule. It occurs when a pitcher throws a complete game shutout requiring fewer than 100 pitches. It is named after Hall of Famer Greg Maddux, who was famous for his incredible efficiency.

9. How much do MLB batboys get paid?

While unrelated to pitching stats, it's a common baseball question! MLB batboys typically make between $10 and $15 an hour, which usually translates to an estimated $20,000 to $30,000 per MLB season.

10. Do 7-inning games change the WHIP formula?

No. Whether you are using a WHIP calculator for a 7-inning softball game or a 9-inning MLB game, the formula remains exactly the same. You just input the actual innings pitched by the player.
