Major

Five year old Goro practices baseball every day to be like his dad Shigeharu, a pro ballplayer,until he injures his elbow and decides to retire.

Goro invites a boy named Toshiya to play catch, reluctant at first, Toshiya comes to love it. Shigeharu vows to make a comeback as a hitter.

A little league coach is dazzled by Goro's raw talent and teaches him to throw breaking balls. But Shigeharu, fearing injury, won't let him play.

Shigeharu is back on the team as a hitter and, on his best friend and teammate's suggestion, looks to remarry, but he's absent on Goro's birthday.

Goro is captivated by Joe Gibson, a major league player now playing in Japan. When Shigeharu homers off of him, Goro is beside himself with delight.

Shigeharu gets beaned by Gibson, but the Blue Oceans go on to win. Goro falls asleep enraptured, but the next day brings anything but joy.

Three years after his father's death, Goro joins the Mifune little league team. The coach welcomes him warmly, but the team has no love for the game.

Kaoru Shimizu joins the Mifune team, but they're still two players short. Goro then runs into his classmate Komori, who's being forced to shoplift.

Komori and Sawamura join the Mifune Dolphins, who now have a full team, but they have to play a game to save the team despite having hardly practiced.

Having learned the importance of teamwork, Goro steps up his game and puts down the adult batters, but his own team can't hit the opposing pitcher.

The Mifune Dolphins have been reborn. Urged by Coach Ando, Goro goes to observe the top little league team in Japan and runs into his old pal Toshiya.

Gibson, now back in MLB, invites Goro to see him play in San Francisco. Though put off at first, Goro wants to see top-level baseball, so he accepts.
