From Wikipedia, the free encyclopedia.
The WHIP (Walks plus Hits per Inning Pitched, “bases on balls and hits per inning pitched”) is the statistic, in the game of baseball, which describes the number of runners a pitcher sets on base in each inning of play.
It is obtained by adding the number of bases balls and valid beats granted by a pitcher to the opposing team, and dividing the sum by the number of innings thrown. The intentional bases granted by the pitcher are included in the count, but not the automatic bases due to a hit from the pitch. A whip of less than 1.00 is considered the standard for a very good pitcher. Conceived in 1979 by writer Daniel Okrent, one of the creators of fantasy baseball[1], measures the pitcher’s performance more adequately than the average PGL, not taking into account errors and unearned points and is one of the most cited statistics in the field of sabermetry.
The record for the season that ended with the lowest WHIP ever belongs to Pedro Martinez, who closed the year 2000 with a WHIP of 0.7373. In MLB history only two pitchers have finished their careers with a WHIP below 1.00, Addie Joss, who closed at 0.9678, and Ed Walsh, with 0.996. New York Yankees great pitcher Mariano Rivera ended his career with a WHIP of 1,0003: in 1,2832⁄3 innings launched, conceded a total of 1,284 between ball and valid bases.
