Now the Lakers Do the Blazing : Pro basketball: They shoot 72% in first half, 64% for the game and roll over tired-looking Trail Blazers, 124-111.

Kareem is gone, Magic pays for his seat and James Worthy started the night shooting 41%, but as long as the Lakers have a pulse, the Portland Trail Blazers have a problem.

Looking as if they had chartered their way here--by bus--the Trail Blazers were overwhelmed Wednesday night by a Laker team that shot 70% until midway through the third quarter, ran up a 26-point lead and won, 124-111.

The Trail Blazers played Tuesday night in Portland, but if fatigue was a factor, Coach Rick Adelman didn’t want to hear about it.

“Sometimes statistics don’t tell the story,” he said, “but when they shoot 72% in the first half and you shoot 44%. . . .

“They just took it to us in every phase of the game. There’s no excuse. We got flat-out beat.”

Sedale Threatt led the Lakers with 26 points. Seven Lakers were in double figures with three minutes left in the third quarter, eight of them by game’s end.

Said Laker Coach Randy Pfund: “When you’re an aggressive basketball team in an attacking mode, which is what we were for three quarters, you can make a lot of things happen, I don’t care who’s on the floor.”

The Lakers, shooting 64% for the game, rolled up an 80-54 lead midway through the third quarter, then saw the Trail Blazers stage a furious rally that cut the lead to 107-99 with about 2 1/2 minutes to play.

But for the visitors, that was as good as it got.

For one Trail Blazer, former UCLA star Tracy Murray, coming home for the first time as an NBA player and starting against the Lakers, it was magic.

“Did I tell you?” Adelman said to Murray, circled by hometown writers before the game.

“You’re not starting tonight.”

For Murray, the No. 4 small forward in training camp, it amounted to a major rally. But Jerome Kersey was hurt and Adelman decided he would rather bring Cliff Robinson off the bench and play Mario Elie at guard, so Murray was in there.

“I never thought it was possible,” Murray said before the game. “I figured I’d get a minute here and there.

“I’m fired up. I just want to keep it at a minimum level. . . . I don’t want to come in there and stink up the joint.”

It turned out, he was the least of the Portland worries.

By halftime, Murray had hit three of his four shots.

His teammates shot 39%.

Meanwhile, the Lakers were firing at an unbelievable 72% clip (26 of 36) and took a 63-46 lead at the half.

If the Trail Blazers didn’t already know they were in trouble, they might have gotten a clue when Elden Campbell came off the bench to score six points in five minutes of the first quarter. Then Campbell hit his fourth, fifth and sixth shots in a row during the second quarter.

The second half was more of the same, until the Lakers had their 26-point lead and the Trail Blazers finally got interested.

“We stunk up this place something fierce,” Terry Porter said.

Now they’re 12-3 against the rest of the NBA, 0-2 against the Lakers.

Laker Notes

Tracy Murray finished with a career-high 20 points. . . . Rick Adelman on Murray: “He’s a great shooter, just a great shooter. As long as I’ve been with this team, and that’s 10 years, there’s been nobody like him. he has range. He hit a three against Cleveland from four-five feet behind the line.” . . . The Lakers have won their last three regular-season meetings against the Trail Blazers. . . . In a scheduling oddity, this was the fifth time in the last six home games that the Laker opponent had played the night before. . . . With Byron Scott and Tony Smith out, Randy Pfund used only two guards, Sedale Threatt and Anthony Peeler. Peeler was hit in the face and went to the floor in the second quarter but got back up. Said Pfund: “We could have been the first basketball team ever to play without any shooting guards at all.” . . . Sign on the scoreboard: “Thanks Jack Haley, I named my puppy after you.”
