Video: 11-year-old Lexi Walker sings the National Anthem

11-year-old Lexi Walker absolutely nailed the National Anthem ahead of RSL's 2-0 win over Vancouver Whitecaps FC on Saturday, hitting all the right notes before getting a huge ovation from the Rio Tinto Stadium crowd.

Players from both sides were clearly feeling the performance, with RSL goalkeeper Nick Rimando going as far as to tweet about it after the match. 

A fifth-grader, Lexi beat out 38 other acts in Canyons School District Idol to win the chance to sing the anthem on Saturday. Check out video of her performance above.
