Youngsters Zach Randolph and Qyntel Woods had big fourth quarters as the Blazers held on for an 87-86 exhibition victory over the Houston Rockets.

Portland again is one of the most talented teams in the NBA. Veterans Scottie Pippen, Ruben Patterson and Arvydas Sabonis sat out, and none of the starters played more than 24 minutes.

Randolph, a second-year power forward buried behind Rasheed Wallace and Dale Davis, scored 10 of his 14 points in the fourth quarter. Woods, a rookie small forward who is stuck behind Pippen, Patterson and Bonzi Wells, scored all six of his in the final period.

Four straight baskets by Randolph gave Portland an 81-71 lead with 4:56 left. Houston fought back within two points before Randolph's layup made it 83-79 with 1:58 to go.

Woods' third long-range jumper of the quarter and a runner by Charles Smith gave the Blazers an 87-82 lead with 1:01 remaining. A layup by Rockets rookie Tito Maddox made it 87-86, but he missed a drive in the final seconds.

Damon Stoudamire scored 12 points, Derek Anderson added 11 and Randolph grabbed nine rebounds for Portland.

Eddie Griffin scored 17 points, Kenny Thomas added 14 and Tierre Brown handed out 10 assists for Houston, which played without Cuttino Mobley (ankle) and Moochie Norris (pinky).

Rockets first-round pick Bostjan Nachbar scored five points. Center Yao Ming, the top overall pick in the draft, is expected to join the team this weekend.
