This was discovered by Evan Coleman who found out that Siri was starting to recognize sports teams as a token (i.e. “New York Yankees” would be read as one token/word rather than three separate words). This coupled with the fact that ESPN had recently released a developers API for accessing sports scores seems to suggest that the ability to pull sports scores via Siri in the future is a very distinct possibility.
However since nothing can be confirmed at this point in time, we’ll try not to get our hopes up just yet, but check back with us in the future as we will keep you updated on the situation.
