The moments leading to Game 2 produced a mixture of emotions for Shawn Marion.

He was about to cover Spurs point guard Tony Parker yet again.

He also was about to become a father.

Marion managed, or perhaps parlayed, basketball familiarity and pre-fatherhood excitement into a 20-point, five-rebound performance in a blowout Dallas win that was just part of an unforgettable Wednesday night and early Thursday morning.

“Everything worked out very, very well,” Marion said with a smile Friday, after the Mavericks’ practice at American Airlines Center.

Marion and the Mavericks carry a 1-1 series tie into Saturday’s potentially pivotal Game 3 at American Airlines Center. And Marion, who turns 36 on May 7, carries new perspective into the rest of his life.

It was shortly before gametime when Marion learned that his son’s birth was near. Marion decided to play, but beforehand he and Mavericks owner Mark Cuban hatched plans for a quick postgame getaway.

After playing a significant role in holding Parker to 12 points and three assists, Marion hurriedly left AT&T Center, flew to Dallas with Cuban in the owner’s private plane, then went on to Chicago.

Marion arrived at the hospital 30 minutes after the birth of his first child, Shawn, but that didn’t lessen the thrill.

“It was great, an incredible feeling,” Marion said. "I have a beautiful, healthy son."

Though this first-round series only two games old, babies have become a common denominator.

The morning after San Antonio’s Game 1 victory, Spurs guard Manu Ginobili and his wife welcomed their third child, a son. Also, Parker and his fiancée expect their first child in about two weeks.

At least one father or soon-to-be father will soon have plenty of time to help with diaper-changing.

Mavericks coach Rick Carlisle’s decision to start games with 6-7 forward Marion guarding 6-3 point guard Parker wasn’t a primary story line in Game 1, when Parker scored 21 points.

Only four of those points came in the second half, though. And after Parker’s scant production in Game 2, everyone wanted to know what Marion was doing to limit Parker.

“I’m used to Shawn,” Parker said with a shrug. “Dallas, they put him on me a lot.”

Parker said Marion also often guarded him as a member of the Phoenix Suns. Parker entered the NBA in 2001. Marion played for the Suns from 1999 to 2008.
