In baseball statistics, walks plus hits per inning pitched (WHIP) is a sabermetric measurement of the number of baserunners a pitcher has allowed per inning pitched. WHIP reflects a pitcher's propensity for allowing batters to reach base, therefore a lower WHIP indicates better performance. WHIP is calculated by adding the number of walks and hits allowed and dividing this sum by the number of innings pitched.
Addie Joss[1][2][3] is the all-time leader with a career WHIP of 0.9678. Jacob deGrom[4] (0.9947) and Ed Walsh[5] (0.9996) are the only other players with a career WHIP under 1.0000.
