Looking at the index “tRA” that shows the goal rate independent of defense …
Sabermetrics has become established as a method for objectively analyzing baseball. One of the indicators is “tRA”. In addition to the three items of walks, strikeouts, and home runs that are not involved in defense, the pitcher’s responsibility is to determine what kind of ball was hit, and to estimate and evaluate the pitcher’s goal rate independent of defense. It’s an indicator. This reveals the power of the pitcher, who is separated from the fielder’s defense. (Numbers are at the end of 27th)
Let’s analyze with this “tRA” and see the team with truly excellent pitching power in the Pacific League. We referred to the data of DELTA Co., Ltd. (https://1point02.jp/), which analyzes using Sabermetrics indicators. The Pacific League team ERA this season will be in the order of Softbank (3.25), Orix (3.31), Nippon-Ham (3.35), Rakuten (3.40), Lotte (3.66), Seibu (3.94). However, the defensive power of each team also has an effect here. So how does this change when separated from defense?
Rakuten, which has the third highest ERA, is 3.48 in the Pacific League first place in “tRA”. Among the pitchers Takahisa Hayakawa and Takahiro Norimoto pitched over 70 innings, they are in the top 10 of “tRA”, and Takayuki Kishi and Masahiro Tanaka are also in the 15th place. Rakuten’s team “UZR” is also No. 1 in the league and has good defensive power, but it seems that they also have excellent pitching power independent of defensive power. It seems that it was the batting line that could not be easily supported that finished in 3rd place.
Following Rakuten is Orix, who won the league title for the first time in 25 years, at 3.51. Absolute ace pitcher Yoshinobu Yamamoto reigned, and pitcher Hiroya Miyagi, who won 13 wins, and Daiki Tajima, who won 8 wins, were also stable. The starting lineup “tRA” was the top of the 12 teams. Third place is Nippon-Ham, the lowest in the league, with 3.55. As for Nippon-Ham, the team’s “UZR” is the league worst -13.8, which suggests that the defensive side had a great influence.
Softbank, which has the highest ERA, is in 4th place at 3.66. It is probable that the team “UZR” was saved by the defense, which was 17.8 in 3rd place in the league, and gave 577 four dead balls in 2nd place in the league, which made the index worse. The pitchers who were excellent in terms of ERA are not outstanding when viewed in “tRA”.
Lotte is in 5th place and “tRA” is 4.18. There is no pitcher who is in the top 10 of the index of pitchers who threw more than 70 innings, and it seems that he struggled with pitching power due to the absence of ace. The bottom is Seibu, and 4.38 is the worst in 12 teams. The ERA is also the worst in the league, but Seibu has an excellent defensive index, and if you limit it to the power of the pitcher, you can see that the current situation is even more difficult.
