Seido has little time to rest after the spring invitational before the Tokyo spring tournament. Their first round opponent is Eigen High School. Kawakami is the lead-off pitcher, but the crowd is expecting Furuya who shone at Koshien Stadium. Will Furuya make an appearance? And what about Sawamura, who was disappointed and Koshien Stadium and is all too aware of Furuya's prowess?

A third-round game at the Tokyo spring tournament is attracting a lot of interest. Inashiro Industrial, the runner-up team from last year's summer tournament with this generation's best southpaw, Mei Narumiya, is facing Yakushi, a quarterfinal finisher from the spring invitational. How have they grown after their winter training and experience in the invitational? Has Narumiya recovered after his disappointing run in the fall? This heavily watched game is about to get under way!

It's the spring tournament semifinal game against Ichidai. After saving his team with his perfect relief pitching, Sawamura is now the lead-off batter in the top of the sixth. Can Sawamura get on base and lead his team in a counterattack? Ichidai Third High's Amahisa's impeccable pitching hasn't allowed Seido a run since the second inning. Will the Seido batters support Sawamura and mount a comeback? Which team will advance to the final?

The game against Hakuryu, a quarterfinalist in the Invitational, is entering the final stretch. What has Sawamura felt and learned facing a nationally ranked powerhouse school? What did Furuya feel and learn watching Sawamura pitch the game on his own? Both pitchers have mixed emotions. Meanwhile, Mima, who also wants to play professionally, has taken an interest in Miyuki.

The Seido baseball team is hard at work preparing for the summer tournament. Meanwhile, the team managers are reviewing notebooks and clippings of newspaper and magazine articles about the team since their appearance at the Invitational. They remember the passionate emotions of Sawamura and Furuya during the games. Seeking consecutive spring and summer appearances at Koshien Stadium, they are striving to improve.

Returning from his injury, Furuya joins a game with the second string. Seeing Sawamura shine in the first string's game, Furuya mulls over the words Kataoka wrote in his journal. Meanwhile, in Yamanashi prefecture, Seido's rivals Yakushi, Ichidai Third High and Inashiro Industrial compete in intense games for the spring Kanto Tournament. Sawamura and his teammates watch intensely as their rivals become stronger.

Sawamura has demonstrated his remarkable growth during the practice games, and people have taken notice, especially his outstanding performance in the Hakuryu game. His pitching has inspired Furuya, too. In the second-string game, Furuya's pitching showed meaningful progress. His emotions transfer into the ball.

Miyuki's team in the Tokyo Invitational is having trouble batting against Wynd Youth's left-handed pitcher Conrad. The American team has the lead going into the seventh inning, when Narumiya finally takes the mound. Meanwhile, Furuya and Ono have formed a battery to take on Yamamori. Ono is quietly eager to help Furuya pitch the way he's used to, even without Miyuki.

On the train home after the Tokyo Invitational game, Miyuki meets Narumiya and gives him some honest advice. They promise an intense battle in the summer tournament. Meanwhile, the fierce game against Seiho on Seido's practice field has come to an end. The Seido nine reflect on their challenges to address, including those from their loss to Yamamori Academy. It's now time to decide the twenty players who will make the roster for the summer tournament.

The summer tournament is in full swing and Seido is playing their second game against Hachiya Oji and their skilled second baseman Kawabata. Furuya is the starting pitcher and has recovered nicely, throwing howling fastballs in the first inning. But Hachiya Oji has been expecting them, and third batter Kawabata hits one which nearly sails into near center field, but Haruchi and Kuramochi are there to stop it!
