Red Sox pitcher Garrett Whitlock learned sign language as his “first language,” according to a video the Red Sox posted earlier this month when they hosted a Deaf and Hard of Hearing night at Fenway Park.
Whitlock’s mother is a sign-language interpreter and taught him sign language when he was a child, according to MassLive.
“I mostly use it in communication with my mom,” Whitlock told MassLive. “She obviously has a lot of deaf friends so I got to communicate with them and really form relationships with them when I was younger.
