Abstract
The Tokyo Big 6 Baseball League (BIG6) and the Tohto University Baseball League (TOHTO) are the top two collegiate baseball leagues in Japan. Both leagues consists of six teams and are highly competitive ; however, there is no opportunity for the teams in the two leagues to compete directly against each other except for the national championships. In this report, we calculate the strengths of six teams across both leagues and compare the superiority of them. Using the Bradley-Terry model and Markov model, we estimate the strengths of each team in both leagues. The Kendall tau rank correlation coefficient of both methods was as high as 0.945. The results indicate that the first team in TOHTO had the highest strength calculated by Bradly-Terry model on the other hand the first team in BIG6 had the highest by Markov model. On comparing the strengths of the same rankings in both leagues, the strengths of every team in TOHTO are higher than those of the corresponding teams in BIG6 in both methods. This is because BIG6 consists of only the same six teams, while TOHTO consists of 21 teams, with the sixth-ranked team playing a replacement game against the first team of the second division every season.
