As the scrimmage starts, Daimon tells Shido he is using Senda as starting pitcher to test his team's fielding. In the top of the first inning, the portable team is quickly retired. In the bottom of the inning, Ko quickly pitches out the first three batters, which Daimon attributes to luck but Azuma recognizes is based on Aoba's batting data and Ko's ability. After Senda gives up three runs in the top of the second inning, including home runs by Ko and Akaishi, Daimon kicks him off the varsity team and Maeno substitutes him in as shortstop for the portable team. Ko pitches fastballs down the middle to Azuma, which Aoba calls foolish and Azuma hits for a home run. The portable team quickly retires the rest of the side but has trouble hitting against the best varsity pitcher. After Daimon chews out his players for failing to hit against "small fry," they manage only one run in the third inning. At the end of three innings with the portable team ahead 3 to 2, Ko complains of being tired.
