Fifth Match (5 回戦, 5 Kaisen) is the eighth episode of season two.
Nishiura's game against Bijoudaisayama starts. Knowing that Abe carefully considers each player's pitch preferences, the opposing team quickly gains runs. Mihashi questions why the opposing team seems to only swing on pitches that seem to be the opposite of what they like, and Momoe and Abe realise that Bijou must have gathered a lot of data on Nishiura. Momoe notices that even the defense against them is skewed toward Nishiura's tendencies. Abe and Mihashi create a sign for a fake refusal of a sign to throw off Bijou. First-inning score is 3-0, and second-inning score is 1-0.
