Walks plus hits per inning pitched
Baseball statistic measuring the baserunners a pitcher has allowed
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 is calculated by adding the number of walks and hits allowed and dividing this sum by the number of innings pitched.[1]
WHIP reflects a pitcher's propensity for allowing batters to reach base, therefore a lower WHIP indicates better performance.
While earned run average (ERA) measures the runs a pitcher gives up, WHIP more directly measures a pitcher's effectiveness against batters.[1] Like ERA, WHIP accounts for pitcher performance regardless of errors and unearned runs.[note 1]
