LOS ANGELES - Despite his limited playing time and a sub-par shooting percentage, Sasha Vujacic says he's never lacking in confidence. And that's a good thing, since a shooter must have that kind of mentality.

Vujacic had his best game in three NBA seasons Sunday night, scoring a career-high 16 points, including a go-ahead 3-pointer with 28.5 seconds left, and the Los Angeles Lakers beat Dallas 101-98 to snap the Mavericks' 13-game winning streak.

Vujacic missed all five shots he attempted Friday night against Denver, dropping his shooting percentage to 37.4 percent, including 31 percent from 3-point range. He shot 6-of-7 against the Mavericks, including 4-of-5 from beyond the arc.

"Always, always," the 22-year-old Slovenian guard said regarding his confidence level. "My teammates found me for open shots. I just wanted to take the responsibility.

"It feels great. The beginning of the season, I didn't start well. I just want to be more consistent, show the coach he can trust me."

Vujacic entered averaging 3.7 points in 11.4 minutes while playing in 27 of the Lakers' 32 games. He played the entire fourth quarter and a total of 19 minutes against the Mavericks.

"I'm really happy for Sasha, how well he played tonight," said Kobe Bryant, who scored 14 of his 26 points in the final period and also had eight rebounds and six assists.

"He comes in off the bench and always plays extremely well defensively, even when he's not shooting well," Bryant said. "I'm proud of him. He's taken his lumps here, the fans have been pretty hard on him. He's a tough kid, he doesn't back down, he's not lacking in confidence."

Luke Walton had 21 points and six assists for the Lakers, who presented coach Phil Jackson with his 900th victory.

"It's a compliment to all the players I've had ¡ª the great players, the great teams and the great runs that we've had," Jackson said. "It's become a game in which us elderly guys are now coaching, which was an age that coaches didn't extend themselves into when I was a player. It says something about the longevity of coaches now."

The 61-year-old Jackson ranks ninth on the NBA's all-time wins list, and became the fastest to reach 900, doing so in 1,264 games. Former Lakers coach Pat Riley accomplished the feat in 1,278 games.

"Nine hundred wins is remarkable," Bryant said. "I can't even fathom 900 games. It was special."

Dirk Nowitzki's jumper with 42 seconds remaining gave the Mavericks a 98-97 lead, but Vujacic's long jumper put the Lakers ahead for good. A free throw by Walton with 10.6 seconds to play completed the scoring.

Devean George, a former Laker, missed a potential game-tying 3-pointer with 4 seconds left, and Bryant got the rebound. Time expired before the Mavericks were able to commit a foul.

The win was the fourth straight for the Lakers (23-11), who played without injured starters Lamar Odom and Kwame Brown. The loss was just the fourth in the last 31 games for the Mavericks, whose 27-8 record is the best in the NBA.

Nowitzki had 29 points and 13 rebounds, Josh Howard had 20 points and nine rebounds, and Jerry Stackhouse scored 14 for the Mavericks.

"Kobe basically took over the game, had some great shots," Nowitzki said. "But really, I think it was the Vujacic guy. Those were points you don't expect. He was hot ¡ª he made big 3s for them."

The Lakers shot 39-of-71 (55 percent) to 38-of-90 (42 percent) for the Mavericks.

"We didn't have our normal fourth quarter," said Mavericks coach Avery Johnson, whose team was outscored 33-21 in the final period. "Everything we tried on them in the fourth quarter didn't work."

Two free throws by Jason Terry with 1:29 to play gave the Mavericks a 96-92 lead, but Bryant made a three-point play with 1:21 left and two free throws with 55.9 seconds to go, giving the Lakers their first lead since the second quarter.

Nowitzki put the Mavericks on top one final time before Vujacic came through, taking a pass from Walton.
