Parker and Duncan help Spurs rout Grizzlies

"On the offensive glass, Tiago did an unbelievable job of fighting back all night," Duncan said. "We had our guards in there battling as well."

A rebound by Duncan led to a 3 by Leonard, extending San Antonio's lead to 80-68 with 2 minutes left in third. The open 3 led Gasol to stare puzzlingly at his teammates on the missed defensive assignment.

"Our defense seemed to be all over the place," Memphis coach Lionel Hollins said. "Guys rotating when they shouldn't be rotating. We had guys out of position playing different spots."

The Spurs' dominance in the final two quarters came after a closely contested first half.

The Grizzlies closed the first quarter on a 19-8 run following a timeout by Hollins. The run included a two-handed dunk by Gay, who soared through the lane to rebound and throw down a missed 3-pointer by Randolph in one motion.

Trailing by as many as six points early in the second quarter, the Spurs rallied behind 13 assists and four 3s.

Jackson and Neal hit consecutive 3s to pull and keep the Spurs within two and Diaw gave them a 40-38 lead with a layup and short jumper.

"I've played with Boris on several teams so I know his game and he knows mine," Jackson said. "Both of us don't mind passing the ball. We were just on the same page tonight and we made great plays for each other."

With Manu Ginobili missing the game with a strained left hamstring, Jackson filled his role as the team's offensive spark off the bench. Jackson had eight points, five assists and a steal.
