Play Ball (プレイボール, Purei Bōru) is a manga series by Akio Chiba which ran in Weekly Shōnen Jump from 1973 to 1978, which was adapted in 2005 and 2006 into an anime series by Magic Bus, aired across Japan on the anime satellite television network, Animax. The series was released concurrently with Chiba's other major work, Captain, the other series for which he won the 22nd Shogakukan Manga Award for shōnen in 1977.
Chiba originally wanted to make the series a rugby or American football [citation needed], but he began to be held up by collecting all the materials needed to make sure he understood the rules well enough to draw an accurate depiction. In order to catch up, he began creating a manga about the high school baseball career of his main character, Takao Taniguchi.
This eventually developed into the series Captain. Play Ball follows the story of the junior high school years of Taniguchi and his fellow teammates.
Nearly twenty-five years later, in 2005 and 2006, the series was adapted into two seasons of an UHF anime TV series in 2005, which was broadcast across Japan by the anime satellite television network, Animax.
