Sebastien De La Cruz Performs Again For San Antonio Spurs In Las Vegas Summer League (VIDEO)

Sebastien De La Cruz became an online sensation - both positively and negatively - during the 2013 NBA Finals in June when he sang the U.S. national anthem at the home games of the San Antonio Spurs at the AT&T Center.

While he turned heads with his overwhelming performance, the 11-year-old Mexican-American also received negative remarks, and was the subject of thousands of hateful tweets after his performance before Game 3 of the 2013 NBA Finals between the Spurs and eventual champions Miami Heat.

Despite the critcism after his Game 3 performance, the Spurs brought him back in their next home games, and on Monday, De La Cruz performed "The Star Spangled Banner" before the Spurs went up against the Atlanta Hawks in a Summer League game at the Cox Pavilion in Las Vegas.

De La Cruz, who was discovered on the hit talent show "America's Got Talent," blew the crowd away with his impressive rendition of the national anthem, earning a standing ovation from a stunned crowd at the Cox Pavilion.

The response from fans on Monday could definitely make De La Cruz a staple at Spurs games next season, USA Today reported.

The Spurs organization, particularly head coach Greg Popovich, came to the defense of De La Cruz when he received a slew of hateful tweets last month. The veteran coach praised De La Cruz for being a class act, calling his detractors "idiots."

"What I was surprised by was how proud these idiots were of their ignorance, by printing their names next to their comments. Way more mature than most his age. And as much as those comments by the idiots saddens you about your country, he makes you feel that the future could be very bright," Popovich told The New York Times.

De La Cruz also responded to the racist comments levied at him. Despite tracing his roots from Mexico, he was born and raised in San Antonio and grew up as a big fan of the Spurs, said De La Cruz.

Juan De La Cruz, Sebastien's father, also served the U.S. navy for several years.
