For the Portland Trail Blazers to avoid missing the playoffs for a fifth straight year, they must continue stringing together wins.

The Trail Blazers will try for their longest winning streak in more than two months on Monday when they close out their season series with the stumbling Seattle SuperSonics, who have dropped 11 straight.

Portland (37-33) seeks to return to the postseason for the first time since 2003, but is currently 10th in the competitive Western Conference, 6 1/2 games behind eighth-place Golden State for the final playoff spot and five behind ninth-place Denver.

However, the Blazers completed a home-and-home sweep of the Los Angeles Clippers with an 83-72 road win on Saturday. Brandon Roy scored 23 points, while LaMarcus Aldridge added 21 and 10 rebounds for the Blazers, who have not won three straight games since winning four in a row from Jan. 2-9.

The Blazers shot just 46.0 percent (74-for-161) in the two victories, but outrebounded the Clippers 87-69. Portland's 53 rebounds Saturday matched a season high set in an 89-79 win over Northwest Division rival Seattle (16-54) on Dec. 25.

Portland center Joel Przybilla grabbed a career-high 25 rebounds Saturday, two shy of the team record set Feb. 26, 1975.

"One of the assistant coaches told me before the game they were probably going to go small, so just try to get every rebound. And that's what I focused on," said Przybilla, who is averaging a team-leading 8.0 boards. "(Friday night) we played at home and I only got three rebounds, so I was upset with myself because that's not me. I take a lot of pride in my rebounding. That's what my job is."

The Blazers have outrebounded Seattle - the league's leader with 44.6 per game - only once in three games.

They are 2-1 against the Sonics, and Przybilla is averaging 12.3 boards. He grabbed 10 in a 99-87 loss at Seattle on Feb. 22 in the teams' most recent matchup.

The Blazers have won five of their last eight on the road, but dropped their last two in Seattle, where they are 2-7 since the start of 2003-04.

Seattle, which begins a seven-game homestand, has lost five straight at KeyArena and is a conference-worst 10-23 at home. The Sonics - 1-15 since their February victory over Portland - extended their losing streak with a 115-101 defeat at Utah on Saturday.

Jeff Green scored a season-high 23 points, while fellow rookie Kevin Durant also had 23 for the Sonics, who are mired in their longest skid since dropping a franchise-record 14 straight from Dec. 31-Jan. 27.

"We played really hard and it was a hard-fought game but they made the big-time shots (Saturday)," said Durant, who is averaging 20.5 points during the slide and 20.0 in three games versus Portland.

The Sonics, owners of the worst record in the West, are trying to avoid losing the season series to Portland for the first time since being swept in four games in 2002-03.

Seattle's Chris Wilcox could miss Monday's game because of a sprained right pinkie finger that has forced him out of the last two contests.
