SAN ANTONIO - Must-win situations are not a familiar place for the San Antonio Spurs.

They survived one Thursday night, earning the chance to play in another.

The defending champions beat the New Orleans Hornets, 99-80 in Game 6, staying alive and forcing a winner-take-all Game 7 on Monday in New Orleans.

“That’s what you want to have, an opportunity,” said Spurs point guard Tony Parker. “That’s why Game 6 was huge. We won the game and now we have an opportunity to win a game on the road.”

Manu Ginobili scored 25 points, Tim Duncan had 20 points and 15 rebounds, and Parker added 15 points to tie the Western Conference semifinals.

The Spurs cruised through last year’s playoffs and to their fourth title in nine seasons without ever facing the threat of elimination.

Before Thursday, the last time San Antonio faced a must-win game was 2006, when they were down 1-3 to the Dallas Mavericks, then came back to force a Game 7 and lost in overtime.

“We know what we’re facing. We’re facing elimination,” Duncan said. “And we know we have to put a good game together there. ... We’re going to take it in there and it’s do-or-die.”

Chris Paul led the Hornets with 21 points and eight assists, and Tyson Chandler scored 14 points. David West had 10 points on 4-of-14 shooting before leaving the game early in the fourth quarter after aggravating a back injury.

“It’s sore right now. Good thing we have two or three days here to get rest and treatment. It’s the way it happens sometimes,” West said.

The aging defending champions and the injured Hornets now get three days off before the deciding game in New Orleans, where the Hornets have won three blowouts.

“Thank God we get to go back to New Orleans for Game 7,” Paul said.

Home teams are 20-1 in the second round of the playoffs.

The Hornets are the No. 2 seed and the Spurs the third. The teams had the same regular-season record, were tied in their head-to-head matchup and had the same division record. The Hornets won the Southwest Division and got the higher seed because they had the better conference record.

“I have confidence,” Parker said. “We’ve won a lot of big games on the road.”

Despite the closeness of the series, Game 6, like the five before it, was won by double digits. It was also won, like those before it, in the third quarter, when the Spurs outscored the Hornets 20-12.

“It’s something about them third quarters,” Paul said. “It’s the same way in New Orleans. In Game 5 they felt like they couldn’t get a break. The same thing for us tonight.”

The Spurs took the lead for good after Parker’s jumper with 4:27 left in the first quarter broke a 17-all tie. They led by as many as 24.

The Spurs hit 11 of 21 3-pointers, led by six from Ginobili. The Hornets had just two 3s. But the Hornets had 48 points in the paint to just 28 from the Spurs.

The Spurs shot 49 percent from the field (38-of-77) to the Hornets’ 41 percent (33-of-80) and outrebounded them 45-40. The Spurs had 28 assists and the Hornets had 13.

The Spurs came out with desperate energy, shooting 71 percent in the first quarter. They led by as many as 13 in the opening period after Bruce Bowen’s 3-pointer made it 36-23. The Spurs took a 36-24 lead into the second quarter.

“I think we lost our focus at the beginning of the game,” Hornets coach Byron Scott said. “They got three quick baskets in the paint, all on the things we talked about not doing. I don’t think our guys were totally focused on what we needed to do. And maybe in the back of their minds they had that false sense of ’Hey, we got Game 7 at home, so just in case we do lose, at least we’re going home for the last one.”’
