Last year Sacco made YouTube fans stand up and cheer with his rendition of Herb Brooks's (played by Kurt Russell) speech from the 2004 movie Miracle. Sacco's YouTube rendition of the monologue became a viral sensation, netting the then four-year-old youngster TV appearances and instant web fame.
Sacco's 15 minutes got a major boost from baseball last night. The boy was invited to deliver the same speech -- adapted for the home team's purpose -- in front of a packed house at Fenway Park.
We've embedded video from last night's fiery speech, as well as Sacco's YouTube original and the Miracle speech that served as the inspiration, below.
