This study investigated the relationship between composite bat technology and 13 offensive statistics. In addition to bat technology it analyzed the relationship between ball Coefficient of Restitution and offensive statistics. The study included 28 NCAA Division I Louisville Slugger Sponsored programs from the 2002, 2003, 2004 and 2005 seasons. All teams were using the same Louisville Composite bat in the 2005 season; the 'Catalyst' and all had the same choices of Louisville bats to choose from in 2002, 2003, and 2004. The ball has been changed from a COR of .50 to a .47. The results indicated that there was no effect for the change in COR, but that there was an effect for change in bat technology. Of the seven statistical categories utilized in the one-way ANOVA, five of them returned a significant result and two did not. The results further indicated that the change in bat is significant in producing more home runs, higher slugging percentages, and better batting averages. The descriptive statistics indicated a dramatic increase in mean home runs and mean hits, with a 45% increase in mean homeruns in 2005
