David Ortiz is one proud dad when his daughter sings the national anthem

On Monday afternoon, the Boston Red Sox faced the Baltimore Orioles in their Fenway opener. Aside from the usual hype, Monday's game had a little more meaning, because it's expected to be David Ortiz's last season. But that's not all. His 15-year-old daughter Alex was set to sing the national anthem:
