Players used metal bats at Koshien with new standards for suppressing repulsive force. Tests conducted by the Japan High School Baseball Federation found that the average speed and initial velocity of batted balls were more than 3% slower.
The number of extra-base hits (double hits or higher) decreased significantly compared to the year before (2022), but it was almost unchanged from last year. NHK's high school baseball commentator says the change in bats may also have an impact on batters' psychological aspects.
