PORTLAND, Ore. (AP) _ Rasheed Wallace scored 21 points as the Portland Trail Blazers defeated the Los Angeles Clippers 92-84 Thursday night in a preseason game.

Shawn Kemp, acquired in a three-team trade from the Cleveland Cavaliers this summer, scored eight of his 17 points in the final 8 1/2 minutes to help the Blazers pull away.

Kemp, derided in Cleveland for his excessive weight and poor work habits, looked heavier than his listed 280 pounds. And he got into immediate foul trouble after coming into the game with 4:11 left in the first quarter, picking up four personals by halftime.

But he worked hard in the final period, huffing and puffing toward the basket and getting to the line.

His 22-foot jumper broke an 82-all tie with 1:39 left, and two free throws extended the lead to 86-82. Los Angeles scored just two points in the final 2:58.

The Clippers led 56-53 at halftime and took their biggest lead at 71-63 late in the third quarter before the Blazers came back. Bonzi Wells got an easy breakaway layup, Stacey Augmon made a 3-pointer and Dale Davis dunked off a pass from rookie Erick Barkley with 1.3 seconds left in the period to pull the Blazers to 71-70.

Davis, acquired from the Indiana Pacers for Jermaine O'Neal, had 13 rebounds.

Nineteen-year-old rookie Darius Miles was impressive in his second preseason game, scoring 19 points to lead the Clippers. Miles, drafted No. 3 out of East St. Louis High, made 7 of 14 shots and had several leaping dunks. In the second quarter he had two steals and scored four points on consecutive possessions.

Portland's Scottie Pippen, who has taken it easy in camp while preparing for his 14th NBA season, did not dress. The Blazers also were without center Arvydas Sabonis, who is recovering from surgery on his right foot and won't be back until late in the eight-game preseason schedule.
