I'm not really too into "sports" anime, but there are a few that I liked despite that fact.
One that really surprised me was "
Princess Nine". I didn't think girls playing baseball could be that interesting, but the first time she threw that pitch and the music swelled, well, I was hooked.
Right now I'm watching "
Eyeshield 21", which is currently up to 114 fansubbed episodes out of over(?) 128 episodes. It's about one high school kid in Japan who is really fast, but kind of a wimp. He gets sucked into an American football team at his school and learns to overcome his weaknesses. Some of the football parts are rather inaccurate (you hardly ever see a referee or a foul called) but the story is a lot more about character growth, so you can usually look past those flaws.
Those are the only two I can think of that I've seen and really liked, but if I recall any later I'll post 'em.
