DALLAS, May 11 (Ticker) -- With the starting frontcourt of the Sacramento Kings on the bench, Bobby Jackson and Mike Bibby kept their guard up.

Jackson fueled a fourth-quarter comeback and Bibby made the go-ahead basket with 12 seconds left in overtime, giving the Kings a stirring 115-113 victory over the Dallas Mavericks and control of their Western Conference semifinal series.

Jackson, one of the top reserves in the NBA this season, started for the injured Peja Stojakovic and had perhaps the best game of his five-year career. After a slow start, he took charge at both ends of the floor, scoring a playoff career-high 26 points and slowing down Dallas by stalling Steve Nash.

Chris Webber scored 30 points while trying to put the series out of the Mavs' reach.

"You're going to make shots and miss shots, but you've just got to continue to shoot when you have shots and just continue to play hard," Jackson said. "My shot started to fall. I was feeling good and my teammates were getting me the ball. That's what it's all about. They recognized that I was hot and they kept getting me the ball."

Bibby, playing in his first postseason, has been spectacular. After collecting 29 points and nine assists in Thursday's Game 3 win, he scored 24 points in this one, including the biggest basket of the game.

"I've got all the faith in the world in him," All-Star teammate Chris Webber said. "I hope that people do start talking about him more, but if they don't, that's OK."

From the left side, Bibby drove past Michael Finley along the baseline and floated into the lane before lofting a short shot over 7-footer Dirk Nowitzki to give the Kings the lead. It marked the only points of the last three-plus minutes for the offensive-minded teams.

"I knew if we ran a pick-and-roll, they would switch, so I tried to go away from the screen," Bibby said. "If I didn't shoot, I was going to pass. Somebody would have an open shot, but nobody came at me."

Dallas had a chance to tie and went to Nowitzki, who had 31 points and 12 rebounds but again struggled with his shooting. The All-Star forward dribbled into the lane and put up a lefthanded layup that bounced out. He could not get a couple of tip attempts up on the rim and the ball was knocked outside as time expired.

"I was right there at the rim and unfortunately it didn't go in," Nowitzki said.

The Kings erased a 12-point fourth-quarter deficit and improved to 4-0 on the road in the postseason. They opened a commanding 3-1 lead and can reach the conference finals for the first time since 1981 with a win at home Monday.

"I expect them to be mad," Jackson said. "We came in and stole two games."

Jackson and Bibby more than picked up the slack for Stojakovic, who is out for the rest of the series with a sprained right ankle; Webber, who fouled out with 4:45 left in the fourth quarter; and center Vlade Divac, who fouled out with 3:56 to go in overtime.

"We tried to switch on them the whole night," Nowitzki said. "Bibby has been pretty much on fire the whole series. Jackson wasn't shooting the ball well in the first half and all of a sudden he explodes in the second half. But that just shows you how good of a team they are."

Webber had 30 points and 10 rebounds and Divac added eight and 14 for the Kings, who dominated the backboards, 54-42, and forced the Mavericks into an uncharacteristic 16 turnovers, including nine by Nash.

"Make (Nash) make plays and try to dictate whatever we're doing," Jackson said of his defense. "That's the biggest thing, really, just contain him and make him make plays."

Michael Finley scored 28 points and Nash added 24 for Dallas, which again shot poorly, making just 43 percent (40-of-93) from the field. The Mavs now are facing history as well, as only six teams have come back from a 3-1 deficit to win a series.

"Well, my worst fear came true," Dallas coach Don Nelson said. "When you lose that first game at home, the concern is that if you drop the next one, you really get yourself between a rock and a hard place. That is really where we are at the moment. We are in big trouble."

Nowitzki made just 9-of-28 shots and is shooting just 35 percent (30-of-86) in the series.

"I tried to force it a little bit," Nowitzki said. "The second half, I just tried to stay aggressive and take it to the rim a little more. It just wasn't a great night."

Two baskets by Finley and a drive by Greg Buckner opened the fourth quarter and gave Dallas a 95-83 lead before Jackson heated up. He scored 11 points in a 17-2 burst that stunned the cowbell-ringing sellout crowd at the American Airlines Center and gave the Kings a 100-97 lead.

"Bobby Jackson was a guy that we couldn't stop, we couldn't handle," Nelson said.

Webber fouled out and huddled his teammates before leaving. Jackson hit two free throws for a 102-99 edge and Bibby drilled a 3-pointer for a 105-101 advantage with 3:44 left.

"(Webber) had played so well," Kings coach Rick Adelman said. "But this team is so resilient. They really believe they can win. They believe they can win no matter what happens."

Nash and Nowitzki had baskets to tie it, but Hedo Turkoglu put home a miss by Jackson for a 107-105 lead with 1:34 remaining. Finley hit a 3-pointer to give Dallas the lead with 1:14 to play, but Nowitzki left the door open for Sacramento by splitting two free throws with 39 seconds to go.

Bibby dribbled right through it, putting in a layup that tied it eight seconds later. Finley and Bibby missed badly on outside shots and the teams went to overtime.

Bibby opened the extra session with a jumper, but Divac fouled out as he hit Nowitzki, whose two free throws tied it. Finley pulled up for a transition jumper before two free throws by Scot Pollard tied it with 3:12 left.

Pollard again was a factor off Sacramento's shortened bench with nine points and eight boards. Doug Christie scored 12 points for the Kings, who shot 48 percent (40-of-84). Raef LaFrentz had 12 points and seven rebounds for the Mavs.

"We basically got good production out of everybody and they beat us," Nelson said. "I think that says something about how good they are."

Both teams changed their starting lineups. The Kings moved Christie to Stojakovic's small forward slot and started Jackson. The Mavs benched forward Johnny Newman, moved Finley into his slot and the slumping Nick Van Exel into the backcourt.

After getting off to quick starts in the first three games, the Kings missed their initial four shots. Meanwhile, LaFrentz made his first four and helped the Mavs open a 12-1 lead.

But Nowitzki missed his first seven shots, and Sacramento got back in it. Webber blew past Nowitzki for a dunk that capped a 10-0 burst and gave the Kings a 25-23 lead.

Finley scored 11 points in the second quarter, including five in a 10-0 run that gave Dallas a 42-30 lead. The teams traded baskets before Sacramento scored with nine straight points. A basket by Webber, who scored 22 points in the first half, closed the deficit to 54-51 at halftime.

Webber picked up four fouls and a technical in the first five minutes of the third quarter and took a seat for the rest of the period. Nowitzki finally found his stroke and scored 15 points in the quarter, helping Dallas open an 89-82 lead.
