The 4th is the last day of the first season of the professional baseball Chunichi spring camp held in Chatan Town, Okinawa Prefecture. Pitcher Ko Neo, a sixth-year pitcher, served as the pitcher during batting practice.
He struggled to control the ball at first due to his strained efforts, and his balls were conspicuously high and wide. However, he gradually recovered, and in order to check the balance of his form, he threw a total of 39 pitches, including breaking balls, and hit five of them.
