What resources can I use to find sports games in my area?

I went to a World Volleyball Federation game (USA vs. Brazil) that a friend told me about and I loved it! But I never heard about it apart from that friend; Yahoo didn't have it and I don't know what local newspapers had it before the game happened - only after the game. What websites or newspapers (or other resource) can I use to find any and all sports games in my area?
