Hard 90 Baseball has been tracking throwing velocity of players for the last 4 years in order to aid in training. The following is a chart offering a rough guideline of the measurements we have collected over the years.
Hard 90 leverages the information in the above chart to help players achieve their goals on the field by developing training programs to achieve desired levels.
Over the years, we have found that most youth players can achieve the average velocity range by simply getting better functional mechanics in their throwing motion. To get into the higher end of the range for youth players, size plays a role; however, some of our smaller players have also tested out at the elite level by perfecting their mechanics.
For our high school players, we find that the most important factors in velocity are 1) sound mechanics, 2) strength and 3) explosion.
