Last I checked, the whole first season of Big Windup (dubbed in English) is available on the Funimation website to stream for free.
It is a baseball anime, but the characters are very colorful and it's funny and intense all at the same time. It may just be baseball, but man they can still put you on the edge of your seat. The first episode is really good and gives you a good feel for who you'll be dealing with as far as characters, and the next few after that set up how the games will play out very well.
Personally I don't have much interest in sports at all, but Big Windup had me on the edge of my seat and craving for more even after episode 26. I know the second season is already out in Japan, but I'm not sure when they'll have it dubbed over.
And the dubbing is very good in my opinion, however I haven't watched enough episodes in Japanese to make an accurate comparison. The translations of the game terminology and figures of speech was very smooth, and it never seemed stilted or in need of explanation.
