Watch This Blind Teen with Autism Sing Spine-Tingling National Anthem

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 shared by MLB 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.

Before singing a note, the crowd members were on their feet cheering on and supporting the teenager. He paused and thanked the crowd before jumping into his pitch-perfect performance.

He first performed when he was in just first grade and since then he's been singing all over the country at various events on behalf of Autism Speaks.
