What Is WHIP?

WHIP stands for Walks plus Hits per Inning Pitched, a key pitching metric in baseball that quantifies how many baserunners a pitcher allows per inning. In simple terms, you add up the number of walks (BB) and hits (H) a pitcher concedes, then divide by the total innings pitched.

Mathematically:

WHIP = Walks + Hits​ / Innings Pitched

Why WHIP Is Valuable

• Indicator of Control and Command: A lower WHIP suggests a pitcher is doing a strong job of limiting free passes and base hits, thereby keeping runners off the basepaths.
• Defense-Neutral Insight: Unlike some statistics that reflect runs allowed (like ERA), WHIP is less influenced by fielding errors or unearned runs — it focuses purely on walks and hits.
• Versatile in Use: WHIP is widely used by coaches, analysts, fantasy-baseball managers, and scouts to assess pitcher performance.
• Historical and Sabermetric Relevance: Because it’s simple yet powerful, WHIP has become a staple in both traditional analysis and advanced sabermetrics.

Interpreting WHIP: What’s Good, Average, or Concerning?

Here’s a rough guideline (used by many statistical tools and calculators):

WHIP Range	Interpretation
Below ~1.00	Elite – indicates excellent control and very few baserunners.
1.00 – ~1.20	Very Good / Great – strong performance.
~1.21 – ~1.30	Average / Good – solid, but not dominant.
~1.31 – ~1.40	Below Average – allowing a fair number of baserunners.
Above ~1.40	Poor / Concerning – indicates trouble with control or too many hits.

WHIP in Context

• With Other Metrics: Pair WHIP with ERA, FIP (Fielding Independent Pitching), or strikeout-to-walk ratio to build a fuller picture of a pitcher’s skill set.
• Trend Analysis: Track WHIP over multiple outings or seasons rather than relying on a single game. Consistency matters.
• Fantasy Baseball: Use WHIP as a key stat to evaluate starting pitchers, especially in formats where minimizing baserunners is rewarded.
• Scouting & Coaching: Coaches can use WHIP to identify pitchers with control issues (high walk rates) or those who are too hittable.

Historical Significance

• WHIP was first conceptualized by Daniel Okrent, who coined it as “innings pitched ratio” back in 1979.
• Some of the all-time greats have posted exceptionally low WHIPs. For instance, Pedro Martínez had a WHIP of 0.7373 in his 2000 season one of the lowest ever recorded.
• On a career level, pitchers like Addie Joss and Ed Walsh are among the leaders in WHIP, highlighting how sustained excellence in limiting baserunners is a hallmark of elite pitching.
