A blind teenager with autism gave the crowd goosebumps as he sang the national anthem at a Boston Red Sox game on Monday night.

A video shows the incredible moment 14-year-old Christopher Duffley took to the field at Fenway Park for the performance.

Christopher was born prematurely, weighing only one pound and 12 ounces and became blind from retinopathy of prematurity.
