Big Windup! Episode Rating Graph

Mihashi a freshman in high-school, and has just transferred to Nishiura High, a school not known for its baseball. But after he gets forced into playing by its new female coach, he befriends the the catcher Abe, who becomes his main supporter in the future.

The baseball team at Nishiura High heads out to a training camp. As everyone is preparing for their first practice match against Mihashi's old school, Abe realizes that the catcher's role is not just on the field but is also to encourage and to protected the pitcher and his well-being.

The practice game between Nishiura High and Mihoshi, Mihashi's old school, is about to start. However before the game starts Mihashi loses his confidence and runs behind the club building, Hatake, the catcher from Mihoshi, followed him and begins to harassing him to the point of threatening to break his arm for the lost games in middle-school. It becomes apparent that Mihashi's lack of confidence stems from the constant bullying and scorn of his former teammates. Mihashi is rescued by Abe who convinces him to play and thus the game begins.

(Nishiura-0 vs. Mihoshi-0: bottom of the 1st – bottom of the 2nd inning) Mihashi is pitching nicely, outing all of Mihoshi’s batters so far. At the top of the 2nd inning, Tajima easily hits Kanou’s forkball. Kanai tries to compete with Tajima and do the same, but strikes out instead. Momoe-san then stresses the importance of the team to work together, because Tajima needs the help of his teammates in order to score runs since he is too small to hit home runs on his own. During the bottom of the 2nd, Kanou explains to Oda the secret behind Mihashi’s fastball, saying that it is “faster than a slow fastball”, which is why it is hard to hit.

(Nishiura-2[Oki & Tajima] vs. Mihoshi-0: top of the 3rd – top of the 4th inning) With nice team work, Nishiura is able to score two consecutive runs easily. Meanwhile, tension is rising between Kanou and the rest of his team. They end up having an argument, but eventually cooled down and resolved to win the game against Nishiura to prove once and for all that Kanou is the better pitcher. Witnessing from the sidelines, Mihashi seems to be longing to join back with his old team, but Abe decides to do his best to get Mihashi to acknowledge him and Nishiura as the team in which Mihashi belongs to.

(Nishiura-2 vs. Mihoshi-3[Yoshi, Oda & Hatake]: bottom of the 4th – bottom of the 7th inning) Going into the bottom of the 7th inning, Kanou finally goes into detail about how great Mihashi’s control really is, and Mihoshi’s substitute coach comes up with a plan. Abe tried to aim for a perfect game (not letting any opposing players to get onto base), but because Mizutani missed the ball, the perfect game was lost. Abe then was determined to have a no hit and no run game, but since Oda followed the coach’s plan, Oda was able to assist his teammate to run home. To make matters worse, Hatake was able to rally by hitting a home run, placing Mihoshi in the lead. However, despite the devastation, Mihashi still has the will to keep on pitching.

(Nishiura-4[Sakaeguchi & Abe] vs. Mihoshi-3: top of the 8th – bottom of the 9th inning) Through good teamwork, Nishiura was able to rally and gain back the lead. After winning the game, Mihashi’s old teammates finally acknowledge their mistakes and ask for his forgiveness and to come back. Mihashi declines, but he says that he liked finally getting the chance to play a proper game of baseball with everyone. After returning back to their training camp, Mihashi finally is able to fall asleep.

(Urasou-2 vs. Musashino-1: top of the 1st – bottom of the 2nd inning) On the way to practice, Mihashi meets Sakaeguchi and learns about how in the Senior League, Abe was teamed up with an “amazing pitcher”. During practice, Shiga-sensei teaches all of the players how to meditate, saying that it will help them build a relaxing reflex that they can use when they are in a pinch. Thus the team starts to perform a 5 minute daily routine of meditating before practice. After a bit of practice, Momoe-san takes the team to go see a spring prefecture (Kantou) tournament game, Urawa Composite (Urawa Sougou, aka Urasou) vs. Musashino First. There it turns out that the “amazing pitcher”, Haruna, pitches for Musashino.

(Urasou-3 vs. Musashino-4: top of the 3rd – bottom of the 9th inning) Abe’s past relationship with Haruna is revealed, showing the circumstances that led Abe to consider Haruna to be the worst pitcher instead of one of the best. However, instead of easing his worries after Abe’s explanation, Mihashi is still extremely intimidated by Haruna because he sees how much of an impact Haruna has been in Abe’s life.

In order to be able to play two practice games, everyone on the team must be able to play at least two different positions. At first, Mihashi is against the idea, but after being reassured that he is the ace of the team and that Abe will always be his catcher, Mihashi accepts the circumstances. Thus Hanai and Oki have the role of substitute pitchers, while the substitute catcher is Tajima. At the end of practice, the team unanimously voted for Hanai to become captain, and Abe and Sakaeguchi become vice-captains. With finals coming up, the team decides to study altogether to make sure that everyone passes. Taking this opportunity in the guise of studying, Mihashi invites everyone to come to his house on his birthday. The team ends up celebrating not only Mihashi’s birthday, but also the birthdays of Hanai and Suyama, whose birthdays had already passed. After eating, Abe shows the rest of the team how truly amazing Mihashi’s control truly is by having Mihashi pitch at his target.

The Summer National Senior High School Baseball Championship Saitama Tournament is about to start. All in all, 170 schools in the area gathered together in order to draw lots to determine who they would be playing against. Unfortunately for Nishiura, Hanai’s bad luck with lottery picking landed them against Tousei for their first game. In order to prepare, Momoe-san makes the team start practice at 5 in the morning since Nishiura’s field doesn’t have any lighting for the team to practice late. After coming back from the tournament meeting, Hamada comes to great the team and officially reunites with his childhood friend Mihashi. In addition, Hamada asks for permission to start a cheer squad on behalf of the baseball team.

During practice, the team, with the addition of Hamada, continue to meditate, but this time start to actively train their relaxing reflex to trigger with the presence of a third base runner. Momoe-san and Shiga-sensei stress to Hamada the importance of the cheer squad, because the mood of the audience can make a break the team’s moral and ability to play.

The team has been working hard to prepare for the game against Tosei, to the point that even Shinooka-chan collapses from exhaustion because she had pulled an all-nighter writing a detailed report on Tosei’s battery and batters. Everyone is getting worked up about the game, including all of the boys’ mothers and also the other members of the cheer squad and audience (over 200 other students) that Hamada was able to recruit.

(Nishiura-0 vs. Tosei-0: top of the 1st inning) The first game of the summer tournament begins. Everyone is present, including the big crowd that Hamada got to come to the game. Mihashi and the team are starting off well; unfortunately, Tajima could not connect with any of the break balls thrown at him and gets struck out.

(Nishiura-1?[Hanai] vs. Tosei-0: bottom of the 1st – top of the 2nd inning) The Tosei batters are getting perplexed by Mihashi’s pitching since the balls appear to be easy, but are hard to connect. During Nishiura’s at bat, Tajima is able to steal (figure out) Takase’s pitching motion, so was able to guide Hanai into stealing second base. However, with two out, Tosei tried to pick Mihashi out, since he was too far away from first base. It’s a race to see whether Tosei can out Mihashi, or if Hanai can reach home first.

(Nishiura-1 vs. Tosei-0: bottom of the 2nd – bottom of the 3rd inning) Tosei still does not know what to make of Mihashi’s pitches, and Nishiura is still hanging on. Nishiura had a chance to get another run in, but the Tosei battery once again made Tajima strike out. During the bottom of the 3rd, Mihashi’s female cousin, Ruri, arrived at the stadium to cheer for Mihashi.

(Nishiura-1 vs. Tosei-0: top of the 3rd – bottom of the 4th inning) Tosei comes back with a counter attack plan, playing to the basics and hitting grounders. Though Nishiura is still hanging onto their lead, they are playing really hard defense. Also, the team is starting to use their relaxing reflex, since there is a “third-base runner”.

(Nishiura-2[Mihashi] vs. Tosei-0: top of the 5th inning) After getting on base because of a dead ball caused by the rain, Mihashi and the rest of his team work hard in order to get one more run before the inning ends.

(Nishiura-2 vs. Tosei-2[Motoyama & Shimazaki]: bottom of the 5th – bottom of the 6th inning) Tosei continue their attack plan, concentrating on hitting Mihashi’s curveball, and manage to get in one run. Nishiura gets into a little mishap, because Mihashi gets a nose bleed, making Abe worry about Mihashi’s condition and whether or not he can pitch. However, it was lucky that this didn’t happen until after the 5th inning, so Mihashi was able to rest for a bit while the field underwent maintenance. The 6th inning doesn’t progress much better for Nishiura, as Tosei ties the score.

(Nishiura-2 vs. Tosei-3[Yamanoi]: bottom of the 6th – bottom of the 7th inning) Though Nishiura is playing a good defense, the lucky breaks that Tosei keep on having make the members of Nishiura seem clumsy. The mound becomes slipper as the rain pours down harder, causing Mihashi to lose his footing and throw a wild pitch, giving Tosei the opportunity to steal another run. To make maters worse, Mihashi’s fever is rising, but after Ruri tells him that Kanou and Mihoshi won their game, “Ren-Ren” has renewed strength and will to pitch the rest of the game.

(Nishiura-3[Suyama] vs. Tosei-3: top of the 8th inning) Tajima once again strikes out, but is able to help his teammates successfully steal bases once he enters the coaching box again. With a nice hit from Mizutani, Suyama gains another point for Nishiura. Hanai also tries to steal another run on the same play, but is stopped by Kawai. Tajima feels down because he hasn’t been able to contribute any runs, but the other guys cheer him up by saying that they will get him another chance to bat once more.

(Nishiura-3 vs. Tosei-4[Kawai]: bottom of the 8th inning) Tosei takes several gamble plays and is able to get one more run in to take the lead once again. On the second attempt at a run, Mihashi paused briefly before throwing the ball back home, for he was afraid Abe would get injured. Abe got angry with Mihashi but assured him that he would keep his promise not to get injured.

(Nishiura-5[Abe & Izumi] vs. Tosei-4: top of the 9th inning) Nishiura is desperate now to get their batters onto the plates in order to have a chance at winning. The team hangs in the game long enough for Tajima to have one more at bat chance, with two runners on third and second base, and two outs. Tajima is finally able to hit Takase’s sinker, thus allowing Nishiura to take back the lead with two runs.

(Nishiura-5 vs. Tosei-4: bottom of the 9th inning) Now that they have the lead, Nishiura must make sure that they don’t allow any more runs. Abe wants Mihashi to keep pitching his fastball, but Mihashi feels insecure, and is practically out of gas. Even still, Mihashi does not want to get off the mount and sticks in there till the very end, only to fall to sleep immediately after the game.

After the game against Tosei ends, Mihashi is taken home to rest since he has a fever. Abe, Hanai, Tajima and Izumi come over to visit him the next day to eat lunch with him and fill him in on what he missed during the previous afternoon’s end of game meeting. They all reassured him that everyone is very happy with his performance, and no one blames him for the runs that Tosei got.
