In this paper, we propose batting index prediction models of 2017. Due to the insufficiency of KBO pitchers data, batting index prediction models of 2016 has been developed based on elected eight batting index collecting the past three years data of MLB and KBO. It has been found that this prediction model fits well to both MLB and KBO, and the KBO model fits better than MLB in some cases. Using these prediction models, we analyzed and compared 2016’s estimated values for the batting index of MLB and KBO. With the relation results between batting index prediction and batter’s age for MLB and KBO, it can be determined that there is no relationship between the significant batting index and ages.
