I watched this anime just on a whim. To be honest, I didn't really give a lot of attention to this anime with its old-style art. A lot more anime looked more interesting, like Shangri-la and Valkyria Chronicles. However, after episode 1, I was hooked.
I laughed, I cried. I can't recommend this anime enough to everyone, even those who don't like baseball.
GO WATCH IT!
