You know, I still can't help but feel a bit lukewarm on this show. It's far from bad, but it's not resonating with me very well. A big part of it might just be the subject matter; I just don't care about baseball. Plenty of other shows that I like deal with mundane subjects, but I at least am interested in them, whether it be fashion or university life. If I have no interest in the subject at all, there's usually still something that keeps me watching. Dezaki's melodrama in Aim for the Ace kept me engaged despite my lack of interest in tennis, for example.
Then there's the matter of visuals; when it comes to animation, I always have a preference for more surreal or abstract visuals. They can elevate even a story dealing with something entirely mundane to fantastic heights (look at Ping-Pong, for example). It really helps me get engaged with a show. It also helps me connect with the characters better, to understand their obsessions a little more. Obviously not all shows have or need that, but it often makes it more appealing to me.
It might be one or both of these things, but for one reason or another it's just not clicking with me. I feel that it's definitely good, but I certainly couldn't bring myself to call it the anime of the season.
