Dirk Nowitzki's new pick-and-roll partner put on quite a show for the old one.

Monta Ellis had 30 points and nine assists, Nowitzki was another of seven Dallas players in double figures with 11 points and the Mavericks beat the Los Angeles Lakers 123-104 Tuesday night.

Steve Nash, Nowitzki's buddy and old running mate, had an up-close view as Ellis did a little bit of everything, scoring on drives and pull-up jumpers while finding open teammates with nifty passing that has come as a pleasant surprise to the Mavericks.

Ellis was 11 of 14 from the field, made all eight of his free throws and had just one of 12 Dallas turnovers against 34 assists.

"The lane was wide open, so I just attacked, and when they came over, I passed the ball and that's what we wanted," said Ellis, who had at least 30 points and eight assists for the second time in his four games withDallas. "Me being aggressive opened everything else up."

Nash was scoreless until the second half and finished with five points. Nick Young led the Lakers with 21.

"We obviously had a hard time containing Ellis," said Nash, who was Nowitzki's teammate in Dallas for the big German's first six seasons. "He got into the guts of our defense all night, getting easy buckets, resting buckets for his teammates and just really spacing us out with his penetration."

The Mavericks never trailed, led by 20 late in the first half and pushed the lead to 26 early in the second half after Ellis got them off to a quick start with a jumper and two assists, including one when Nowitzki took the pass and ducked under a defender's arm for the layup.

"Monta Ellis was fantastic tonight, all aspects of the game," Dallas coach Rick Carlisle said. "He defended, he made plays at the rim, he was under control, he hit midrange shots, he hit guys cutting to the basket."

Jose Calderon had 12 points on 4-of-6 shooting from 3-point range, including one that put Dallas ahead 90-60 with 4:33 left in the third quarter. The Mavericks were 13 of 27 from long range.

The Lakers tried to make it interesting with a 19-4 run, but DeJuan Blair stopped it by blocking a layup attempt by Chris Kaman, leading to a 3-pointer by rookie Gal Mekel after Nowitzki passed out of a double team.

Mekel scored again on layup off a steal from Blair, who had 10 points — all in the first half — and eight rebounds.

Jae Crowder kept the Lakers from getting any closer by going 4 of 4 from 3-point range in the fourth quarter, and getting a breakaway dunk on assist from Ellis. He finished with a career-high 18 points.

The top three scorers came off the bench for the Lakers, who were blown out for the second time in two road games without Kobe Bryant. After Young, Jordan Farmar and Jodie Meeks had 11 apiece.

"You can't get blown out and then think now we need to learn to win," Lakers coach Mike D'Antoni said. "No, we need to learn how to play. We're not playing right now. We don't come out with the same grit and determination."
