No Hitter Alert Service

With about a month left until I head back to work (and a month and a week until the kids come back), I'm looking at finally getting around to writing a script to automatically send out an alert when the no hitter watch is on.  Here's how my back of the envelope plan looks:  Script reads in a webpage that has all the game linescores for that day.  Script scans the linescores looking to see if a game has any hits.  Once a certain inning is reached (possibly user definable?) an alert gets sent out via rss/twitter/email.  The email contains teams, inning, score, and pitcher with the no-no going. 

I wrote a little program to scan minor league teams for statistics off thebaseballcube so I'm not completely out of my element on this one.  The only technical hurdle will be learning how to post to twitter/rss.  That's doable.

So here's what I'm asking you for:  Sites that you use to get in game line scores.  Preferably it lists teams, score, hits (obviously), and current pitchers.   The better the site is about updating the better the service will work.  I usually use yahoo sports when I want to know a line score, but I don't think they're always as updated as some other sites.  If you've got a better one I'm more than happy to look at it.

I've done some searching around and haven't found anything like this, but if somebody has a link to a place that already does this I'd be more than happy to go back to watching NCIS and House reruns on USA for the next month.  I'll leave it to somebody else to write the script to monitor Closed Captions from CNN/Fox/MSNBC to look for car chases.
