In this study, the correlation between the sabermetrics index and the WAR of Korean professional baseball pitchers was analyzed. The purpose of this study is to suggest what meaningful records are needed for professional baseball players to recruit or use athletes. For this purpose, the pitcher's WAR, innings, wins, ERA, FIP, AVE, OBP, SUG, OPS, home run, WHIP, walks, strikeout, quality start, BABIP index. A correlation analysis using SPSS 21.0 was performed. The results showed that FIP was the most relevant indicator. Also, there was a high correlation between strikeouts, OBP, WHIP, OPS, and quality start. On the other hand, the inning, wins, walks, AVE, SUG, BABIP, and home runs were relatively low or fluctuated by season. This study confirms that the detailed indicators such as FIP, quality start, and WHIP a re c losely r elated to the WAR rather than the current awards such as ERA, inning s, and wins. The team should consider FIP, strikeouts, OBS, WHIP, OPS, and quality start capabilities when recruiting, nurturing and using pitchers.
