Abstract

Wins above replacement (WAR) is the most commonly used statistics of the sabermetrics that measure baseball players' abilities. The advantage of a WAR is that it enables to compare performances of players even though they have different roles such as pitcher and hitter. However, WAR is difficult to obtain with common records. Thus, a past studies (Lee and Kim, 2016) suggested the batting ability index to determine the ability of the batter focused on the sabermetrics statistics WAR. In this paper, we selected the best hitter with applying Korea baseball 2016 data based on a proposed model and then observed a total raking of others according to BAI. We are assured that BAI is very excellent statistics through comparing BAI and WAR which is in the spotlight in evaluating performances of players.

야구선수들의 능력을 측정하는 많은 세이버메트릭스 통계량들 중에서 대체선수대비승수 (WAR)은 가장 많이 사용되는 통계량이다. WAR의 장점은 투수와 타자처럼 서로 다른 포지션임에도 불구하고 선수들의 WAR을 비교할 수 있다는 점이다. 하지만 WAR은 복잡한 형태로 일반적으로 제공되는 기록만으로 구하기 어렵다. 따라서 지난 연구 (Lee와 Kim, 2016)에서는 2013-2015년 KBG 기록을 바탕으로 WAR에 가장 근접한 타자의 타격능력지수를 제안하였다. 본 논문에서는 제안된 모형을 바탕으로 2016년 KBO 데이터를 적용하여 2016년 최고타자를 선출하고, BAI에 따른 타자들의 전체 순위를 살펴보았다. 그리고 죄근 선수를 평가함에 있어 가장 각광받고 있는 WAR과 BAI의 비교를 통해 BAI가 매우 뛰어남을 확인하였다.
