In this paper, a relationship is obtained between the best hitting point of the baseball and the natural frequency and the modal shape of the baseball bat through a finite element model. Assume that the material of the baseball bat model is linear elastic, and both ends of the bat are traction free, as is consistent with the actual situation, then we may discuss the ＇corking＇ of the bat （digging a cylindrical cavity at the head of the bat, putting a cork or rubber into it, and then covering it with a wood cap） or the use of metal bats. Both methods can increase the effect of ＇the sweet point＇. The validity of the model is verified by experiments.
