Original Article
<div style="text-align: justify;"><strong>Background. </strong>There is a weakness that the win-loss ranking model in the MLB now is calculated based on the result of a win-loss game, so we assume that a ranking system considering the opponent’s team performance is necessary.<br>
<strong>Objectives. </strong>This study aims to suggest the PageRank algorithm to complement the problem with ranking calculated with winning ratio in calculating team ranking of US MLB.<br>
<strong>Methods. </strong>PageRank figure is calculated by using the result of 4,861 matches in the 2017 season (2,430 matches) and 2018 season (2,431 matches) in the MLB.<br>
<strong>Results. </strong>There is a difference between ranking calculated in PageRank and ranking calculated with winning ratio both in the 2017 season and 2018 season, and there is a difference in performance per each district due to comparing performance per each league and district. In addition, as a result of calculating the predictive validity of PageRank and winning ratio ranking, it turns out that the ranking calculated with the PageRank algorithm has relatively high predictive validity.<br>
<strong>Conclusion. </strong>This study confirmed the possibility of predictive in the US MLB by applying the PageRank algorithm.</div>
