Patty Mills' hilarious reaction to Ginobili's standing ovation

San Antonio Spurs veteran Manu Ginobili may have just played his final NBA game, but teammate Patty Mills was still playing the prankster.

Ginobili, 39, is out of contract after the Spurs were swept by the Golden State Warriors in the Western Conference finals.

He was given his first start of the season by coach Gregg Popovich out of respect following Ginobili's 15-year NBA career that yielded four championships.

But while Ginobili conceded after the game that he is not yet sure on retirement, the San Antonio's AT&T Center home crowd cheered 'Manu! Manu!' as he went to the bench for the final time.

Aussie teammate Mills, though, couldn't help but produce a lighter moment.

"What are they standing up for?" Mills appeared to ask Ginobili of the crowd.

The Argentine, for his part, shrugged off his red eyes to joke that he had no idea why the fans were cheering.

Ginobili later left the court with one finger raised up to the fans and would go on to tell reporters that he will decide on his future in the next month.

"I do feel like I can still play but that's not what is going to make me retire or not," he said.

"It's about how I feel, if I want to go through all that again.

"It felt like (the fans) wanted me to retire, like they were giving me a celebration night.

"And of course I'm getting closer and closer. That's no secret. It's getting harder and harder but I always say that I wanted to let it sink in for three weeks, four weeks. And then I'll see with my wife and how it feels."

Ginobili went scoreless in the first four games of the playoffs late in April but had produced some of his best basketball against the Warriors.

He scored 17 points in game one, a season-high 21 in game three and 15 - along with seven assists - in the final game of the series, and potentially his career.
