What is WHIP in Baseball?
WHIP stands for Walks plus Hits per Innings Pitched. It is one of the most important statistics for evaluating a pitcher's effectiveness at preventing batters from reaching base.
WHIP Formula
WHIP = (Walks + Hits) / Innings Pitched
Components
- Walks (BB): Total bases on balls allowed by the pitcher
- Hits (H): All types of hits allowed (singles, doubles, triples, home runs)
- Innings Pitched (IP): Total innings pitched, including partial innings
Understanding Innings Pitched
Partial innings are recorded as fractions:
| Display | Meaning | Decimal |
|---|---|---|
| 6.0 | 6 complete innings | 6.000 |
| 6.1 | 6 innings + 1 out | 6.333 |
| 6.2 | 6 innings + 2 outs | 6.667 |
WHIP Rating Scale
| WHIP | Rating | Description |
|---|---|---|
| ≤ 1.00 | Excellent | Elite pitcher, Cy Young caliber |
| 1.01 - 1.10 | Great | Top-tier starter |
| 1.11 - 1.20 | Above Average | Quality pitcher |
| 1.21 - 1.30 | Average | League average |
| 1.31 - 1.40 | Below Average | Room for improvement |
| > 1.40 | Poor | Struggling to prevent baserunners |
Example Calculations
Example 1: Starter with good control
- Walks: 25
- Hits: 150
- Innings Pitched: 180
- WHIP = (25 + 150) / 180 = 0.972 (Excellent)
Example 2: Mid-rotation starter
- Walks: 45
- Hits: 175
- Innings Pitched: 160
- WHIP = (45 + 175) / 160 = 1.375 (Below Average)
Historical Context
WHIP was invented in 1979 by Daniel Okrent, who originally called it "innings pitched ratio." It has since become one of the standard metrics for evaluating pitchers.
Notable Career WHIPs (All-Time)
| Pitcher | Career WHIP |
|---|---|
| Addie Joss | 0.968 |
| Ed Walsh | 1.000 |
| Mariano Rivera | 1.000 |
| Clayton Kershaw | ~1.00 |
| Pedro Martinez | 1.054 |
Why WHIP Matters
- Predictive: Correlates well with future performance
- Simple: Easy to calculate and understand
- Comprehensive: Captures both walks and hits in one metric
- Baserunner Focus: Directly measures traffic on the bases
Limitations
- Doesn't account for extra-base hits vs. singles
- Hit batters are not included
- Doesn't consider defensive support
- Errors allowing runners don't count against WHIP
Note: WHIP should be used alongside other metrics like ERA, FIP, and K/9 for a complete picture of pitcher performance.
📐 The Formula
WHIP = (Walks + Hits) ÷ Innings Pitched
Fun Fact: WHIP was invented by Daniel Okrent in 1979. He originally called it "innings pitched ratio" before it became known as WHIP.
