Teen who is blind and has autism beautifully sings National Anthem at Red Sox game

A 14-year-old boy who is blind and has autism made a harmonious home run with his moving performance of the Star Spangled Banner at Fenway Park this week.

Christopher Duffley was invited to perform the National Anthem in front of a crowd of thousands at Monday's matchup between the Boston Red Sox and the Cleveland Indians. The Manchester, N.H. teen's passionate performance evoked a roar of cheers from the audience.

Christopher was born prematurely and rendered blind due to retinopathy of prematurity, according to his website. At a young age, Christopher was discovered to have perfect pitch, beginning his passion for singing. The teen now sings at events across the country, including two previous appearances at Fenway Park in 2011 and 2013.
