In the first seven innings, the two sides were evenly matched, tying at 4-4;
Then, at the bottom of the eighth inning, with the bases loaded and one out, the second baseman of Hachinohe Institute of Technology, Nakamura Kouda, hit a triple to right field against Eimei's pitcher's low-breaking ball, successfully clearing the bases. He then returned to home plate with the help of a teammate's sacrifice fly, changing the score to 8-4 and helping Hachinohe Institute of Technology achieve a historic breakthrough, advancing to the next round.
