The sizzling Portland Trail Blazers extended their winning streak to 11 games with an 89-79 victory over the Seattle SuperSonics Tuesday night at the Rose Garden Arena.

With Brandon Roy and Jarrett Jack scoring 17 points each, the Blazers moved just a half game behind Northwest Division leader Denver and gave their fans a perfect Christmas present.

This is the Blazers’ best run since winning 12 straight during the 2001-2002 season. Steve Blake and Channing Frye contributed to Tuesday’s victory with 12 points each while center Joel Przybilla had 16 rebounds.

“We're figuring out ways to win every night… We know we have to play well at home. The fans deserve it, and we deserve it for working hard,” Frye said.

Seattle’s rookie Kevin Durant netted 23 points, Wally Szczerbiak added 19 but it wasn’t enough for the SuperSonics and they had to face defeat for the third time in four games.

At halftime Portland led 46-44 but Roy wasn’t shining as usual. The 23-year-old guard broke loose after the break and poured in 13 points, helping the Blazers to reach a comfy advantage.

“In the first half, I was looking for contact,” Roy said. “In the second half, I was just trying to be aggressive and get to the basket.”

The final minutes kept the home crowd on the edge of their seats, with Seattle raging to a 74-68 three minutes into the final frame. But the Blazers kept their cool, Jarrett Jack sealing the win with a triple.

In other games, the Los Angeles Lakers beat the Phoenix Suns 122-115 at Staples Center. Kobe Bryant scored 38 points, while 20-year-old center Andrew Bynum added 28 points for the Lakers ninth win in 11 games.

“I think we are a solid team. When you play against Phoenix, you have to be solid,” Bryant said.

Meanwhile the Cleveland Cavaliers trampled Miami Heat 96-82, LeBron James scoring 25 points. Drew Gooden netted 18 points, Daniel Gibson 16 and Brazil's Anderson Varejao 15 for the Cavaliers.

“When we play defense, we're a pretty good team. When we don't, we don't look so well - simple as that. Today was a good step,” James said.

Even if Dwyane Wade tossed in 22 points, the Heat had to face defeat once again and occupies the last place in Eastern Conference.

“It was an absolute, complete turnaround,” Miami’s coach Pat Riley said. “The turnovers led to fast breaks that got them close. Then they go the 15-0 run.”
