Some of Ide and Okada's conversations are present only in the anime.
When Nabae comments about Eiichiro having difficulties on volleying shots near the dominant hand, the manga mentions that Eiichiro is using a Continental Grip. The anime did not mention anything about the grip Eiichiro uses.
In the manga, when Eiichiro sees Natsu, Natsu is with Yukichi and others, and they are located behind Nabae. In the anime, Natsu is alone behind Nabae and Yukichi and others are behind Eiichiro.
