Walks and Hits Per Inning Pitched (WHIP) is a pitching statistic that details the average number of hits and walks a pitcher allows on a per inning basis, which gives an indication of how often a pitcher lets batters to reach the bases.
More about Walks and Hits Per Inning Pitched Leaders
Pitching walks and hits per inning pitched (WHIP) leaders are those who allow the fewest number of combined walks and hits allowed for every inning they pitch. Though this has a reputation as something of an “advanced” statistic the computation is actually very simple as it just the sum of walks and hits allowed divided by all innings pitched. As pitchers have become more dominant in recent years it is becoming more common for the league leaders in WHIP to have a ratio below one. It is not a perfect statistic, as it does not differentiate between, for example, a walk allowed with nobody on and a home run allowed with the bases loaded, but is still useful in looking at the frequency in which batters safely reach base (though it does not include hits batsmen or catcher’s interference in the calculations).
