Walks and Hits per Inning Pitched (WHIP) is a statistic used in baseball to measure a pitcher's effectiveness. It calculates the number of walks and hits a pitcher allows per inning pitched. A lower WHIP indicates that a pitcher is more effective at preventing runners from reaching base. To calculate WHIP, you add the total number of walks and hits allowed and then divide that sum by the total innings pitched. This metric helps teams and fans evaluate a pitcher's ability to control the game and limit scoring opportunities for the opposing team.
