Again, the company I work for offers this kind of data but you have to pay for it. We have lots of clients who run fantasy baseball web sites and make use of our real-time stats feeds to update their games.
Do you ever have any issues with leagues about using their data? I figured something like this would be a good idea, to format stats etc, but thought I might get in trouble for using "their" stats inappropriately or whatever.
We offer stuff ranging from simple on-demand calls to our web service (you purchase credits, docs cost you X credits per access) to a Perl-based app that captures an XML feed and parses and inserts the data into a DB for you to use as you will at your end, usually MySQL but we support MS-SQL too.
We've got some pretty big clients: ESPN, USA Today are amongst them. We supplied Google with Olympic content during the Beijing Olympics.
