The show follows the trials and tribulations of country bumpkin Eijun Sawamura, who wins a sports scholarship to attend a prestigious high school in Tokyo to play on their baseball team.
He arrives late on his first day and gets pranked by his classmates. From here things spiral downwards for Eijun, as the coach tells him he won't be playing with the team any time soon. All he can do is run laps until the coach says otherwise.
Determined to improve, Eijun announces that he will be the team's ace pitcher, but is laughed at by his teammates. Later he finds out the shocking truth - there are more than 100 players on the team, and all of them are vying for one of the nine top positions. If you fail to perform well in a match you're replaced.
High school baseball is a cutthroat game. Will Eijun become the ace pitcher as hoped?
The show is based on the manga of the same name written and illustrated by Yuji Terajima. The serialisation in the anthology Weekly Shonen Magazine began in 2006 and is ongoing. Keep an eye out here for this show to be on a local channel soon.
