Jordin Sparks sang the national anthem at game four of the NBA finals on Friday (June 9), delivering what might be the last performance of the series.

The American Idol-winning singer kicked off possibly the final face-off between the Cleveland Cavaliers and the Golden State Warriors, who lead the series 3-0. The first team to win four games will be crowned the NBA champions.

To her credit, Sparks sang like the champion she is before the packed Quicken Loans Arena in Cleveland, Ohio, delivering a flawless performance and nailing the high notes.
