Tony Parker was nursing a sprained left ankle and playing a critical playoff game on no sleep only hours after the birth of his first child.

It was the perfect formula for a resurgent performance from the San Antonio Spurs point guard.

Parker had 23 points and five assists and San Antonio never trailed in a 109-103 victory over the Dallas Mavericks on Wednesday night, taking a 3-2 lead in the first-round series.

“Coming into the game I told him this is perfect for you,” Spurs forward Tim Duncan said. “This is what he does in situations like this where he doesn’t get a lot of sleep or is in a stressful situation. He always seems to play better. I somewhat expected it from him.

“He was really excited before the game. Obviously, he was really excited to have his son here and wanted to get this game really badly not only for his son but for the situation and the timing of it. He was really focused and it was good for us.”

Parker’s rebirth put San Antonio on the verge of closing out a tense series against its intrastate rival with Game 6 set for Friday in Dallas.

Vince Carter scored 28 points on 10-for-16 shooting for the Mavericks.
