This paper analyzes the literature surrounding the relationship between MLB pitcher velocity, pitcher injury time, and hit batsmen which indicates that pitcher velocity is likely the cause for higher injury rates and an increase in batters hit. Two linear regression models were used to examine both of these relationships. The data set included average pitcher fastball velocity, number of pitches, time injured, and the number of hit batters for pitchers who threw more than one hundred fastballs in any year between 2015-2022. The first regression found no significance between velocity and time injured however the relationship was positive. The second regression displayed a high negative significance which did not support the hypothesis. Given these results, this paper puts forth possible improvements to the data which could improve the results to align with the hypothesis.
