Problem: The purpose of the study was to determine if these was my difference between the number of strikes thrown by high school boys with pitching experience in baseball, when pitching from the right, left or center section of the pitching rubber. Procedure: The subjects were thirty right handed boys of Sycamore High School. The subjects were randomly assigned to three groups for the purpose of starting position. These groups were assigned a beginning position of left, center or right on the pitching rubber. The subjects were placed into two squads for their throwing days. Each squad consisted of fifteen boys, with five subjects from each position group. Each squad underwent a three-day instructional and practice period. After the training period, each subject was tested for the number of strikes thrown. Squad I threw on Monday and Wednesday while Squad II threw Tuesday and Thursday. Each subject threw ten pitches from each of three positions on both days of throwing. The strike zone was used in this study had a top dimension of fifty-two inches off the ground while the bottom dimensions was seventeen inches off the ground. The strike zone was constructed by the use of two volleyball standards and strings for the vertical and horizontal measurements. A recorder kept score of the number of strikes thrown on a score sheet. The data accumulated from the testing were statistically analyzed to determine the difference between the means of the three groups. Findings and Conclusions: The findings of the study were as follows: 1. The number of strikes thrown by the subjects on the second day of the test was not significantly different from the number thrown on the first day. 2. The number of strikes thrown on Monday and Wednesday did not differ significantly from the number thrown on Tuesday and Thursday. 3. The number of strikes thrown by the subjects was not significantly different when throwing from the starting, middle or finishing position on the pitching rubber. 4. The number of strikes thrown by the subjects was not significantly different when throwing from the right, center, or left section of the pitching rubber. The following conclusions were drawn as a result of this study of high school boys using a fastball delivery: 1. The day pitches were thrown was not a factor in the number of strikes thrown. 2. The order of positions on the pitching rubber was not a factor in the number of strikes thrown. 3. Throwing from the left, center or right of the pitching rubber did not affect the number of strikes thrown by the subjects.
