Bonzi Wells scored 10 of his 18 points in a huge second quarter as the Trail Blazers coasted to a 125-103 rout of the Dallas Mavericks, forcing a seventh game in their Western Conference first-round series.

Portland dropped the first three games of the series to extend its playoff losing streak to 10 games, one shy of the NBA record. But the Trail Blazers have resurrected themselves in a week, becoming only the third NBA team to tie a series after losing the first three games.

No NBA team has ever won a series after trailing, 3-0. Game Seven is Sunday at Dallas.

"I think they're a little scared now, they've got their backs against the wall," Portland forward Ruben Patterson said. "We were down 3-0, we came back. Now they know we're going to be tough. ... I can't wait for Sunday."

Zach Randolph collected 21 points and 10 rebounds and Patterson added a playoff career-high 20 points for the Trail Blazers, who matched a franchise playoff record with 59.8 percent shooting (49-of-82).

"My whole message is the series isn't over until one team wins a fourth game," Trail Blazers coach Maurice Cheeks said. "Now we're down to that. Once the ball goes up Sunday, everything is equal."

Portland held a 27-24 advantage after one quarter before simply burying Dallas in the second period. Rasheed Wallace drained a 3-pointer that triggered a 19-3 tear as the Trail Blazers built a 46-27 cushion with 6:18 left before halftime.

Wallace scored nine of his 13 points in a period that saw Portland outscore Dallas, 37-14. Damon Stoudamire's jumper with three seconds left before the half made it 64-38, sending the Rose Garden crowd into a frenzy.

"We believed from the beginning and the fans here, they believed in us," Wallace said. "There were a couple of people here that counted us out, but everyone was out here today and they saw it. We were just not ready for it to end."

Dallas superstar Dirk Nowitzki was held to four points on 2-of-11 shooting. Nowitzki averaged a playoff-leading 34.8 points in the first five games of the series.

"We played well on our home court and did not win on Wednesday and I thought tonight's game would be close, so, no, I didn't see this coming," Dallas coach Don Nelson said. "It didn't matter what we did, when they made that run in the second quarter, we couldn't stop it."

Steve Nash finished with 21 points and six assists and Michael Finley scored 20 points for Dallas, which rested its "Big Three" the entire fourth quarter. The dispirited Mavericks have not lost four straight since a six-game skid from February 29-March 9, 2000.

"I thought they were really active defensively," Nowitzki said. " They played with a lot of emotion. I thought we were really good in the first quarter. But the bottom fell out after that and it wasn't much of a game. He just dismiss it as that and move on." Six Trail Blazers scored in double figures as the team displayed a level teamwork and cohesiveness that was absent in their losses. Portland finished with 32 assists as Wallace and reserve Jeff McInnis each had six.

Arvydas Sabonis scored 16 points on 7-of-8 shooting and Stoudamire finished with 14. Wells made 9-of-14 shots and Patterson was 8-of-10 from the floor.

"We just wanted to get one victory, and once you get one victory, anything can happen," Stoudamire said. "I've been in a seven-games series where we've been down 3-1, a couple of my teammates have. I don't think we've ever had panic."

Portland shot 59 percent (16-of-27) in the second quarter while Dallas clicked at just 26 percent (5-of-19) over the decisive 12-minute span.

"Everybody who stepped on the floor for us, played good defense," Cheeks said. "Our defense was the big thing."

The Trail Blazers held a commanding 45-32 edge on the glass. Sabonis grabbed eight and Wallace, Stoudamire and Wells all finished with six.

"Today obviously we couldn't rebound," said Nowitzki, who failed to grab a rebound. "This has been a key for us the whole year. If we don't rebound the ball, we're in trouble. Today was just an awful rebounding game again."

The big first half for Portland came without forward Scottie Pippen, who is still feeling the effects of a sore left knee. Pippen played seven minutes in the second half and finished with four points.

Pippen's jumper with 1:24 left in the third quarter gave Portland its largest lead, 95-63.

The Mavericks actually got off to a decent start as a jumper by Finley gave them their largest lead at 18-11. Sabonis and Stoudamire each scored four points in a 16-4 tear that gave the Blazers the lead for good.
